Mixed Results

Since the last blog post on January 6th, there have been new state-level polls in New Mexico, Iowa, Arizona, Michigan (x2), Georgia, Nevada, Wisconsin (x2), Connecticut, Florida, and West Virginia.

These polls have, in general, shown mixed results. Some move toward Trump, some step toward the Democrats. For some, it depends which Democrat you are watching.

Add everything in from all the states, and you end up with a pretty neutral update on the probabilistic view, with no massive moves, and the changes we do have going in different directions.

Let's look first at the median margins in the Monte Carlo simulations:

Dem 6 Jan 19 Jan šš«
Biden +132 +126 -6
Sanders +46 +48 +2
Warren +2 +4 +2
Buttigieg -48 -50 -2

Two Democrats improve against Trump, two diminish. But none of these move very much from where they were.

It is worth noting that between the last update and this one, Warren vs. Trump did briefly flip to the median being a six electoral vote Trump win. But then that reversed and ended up with Warren being slightly better off than she was.

When you look at the four curves, it seems POSSIBLE that we have hit an inflection point. After several months of the curves moving towards Trump, have we now changed direction?

I would urge caution on that interpretation. It is premature. Notice that there was a similar "bump" back toward the Democrats in November. But it was short-lived, and the longer-term trend continued.

So, on the whole, no big moves this update.

Now in terms of win odds:

Dem 6 Jan 19 Jan šš«
Biden 99.5% 99.2% -0.3%
Sanders 78.0% 79.9% +1.9%
Warren 50.8% 52.4% +1.6%
Buttigieg 14.4% 14.2% -0.2%

Between these updates, Biden had briefly dropped below 99%. But he rebounded up to 99.2%. Not quite the 99.9%+ he had back in September, but still very strong.

Sanders and Warren both improve a little bit here, with Sanders continuing to be weaker than Biden, but much stronger than Warren, who is barely better than a coin toss.

And Buttigieg, well, at the moment he continues to look like cannon fodder for Trump if that was the matchup.

Looking at the older categorization view, in terms of straight-up changes to the categories I put states in, four changes were good for the Democrats, and three changes were good for Trump.

Moves toward the Democrats:

  • Sanders: New Mexico moved from Strong Sanders to Solid Sanders
  • Warren: Iowa moved from Strong Trump to Weak Trump
  • Warren: Michigan moved from Weak Trump to Weak Warren
  • Buttigieg: Arizona moved from Strong Trump to Weak Trump

Moves toward Trump:

  • Sanders: Georgia moved from Weak Sanders to Weak Trump
  • Biden: Michigan moved from Strong Biden to Weak Biden
  • Buttigieg: Iowa moved from Weak Buttigieg to Weak Trump

With the categorization view, we're simplifying and only say how the electoral college would look if every candidate won every state where they lead the average, rather than noting how often close states could flip to the underdog. But with that view, things look like this:

Dem 6 Jan 19 Jan šš«
Biden +178 +178 Flat
Sanders +58 +26 -32
Warren -44 -12 +30
Buttigieg -60 -84 -24

The changes here are more significant than in the probabilistic view because when a state goes from just barely one side, to just slightly on the other, it makes a huge and immediate difference.

Here only Warren actually improves from where we were at the last update, but she still loses to Trump.

Then the tipping points:

Dem 6 Jan 19 Jan šš«
Biden +4.3% +3.0% -1.3%
Sanders +1.0% +0.1% -0.9%
Warren -0.5% -0.5% Flat
Buttigieg -1.8% -1.6% +0.2%

On this view, only Buttigieg improves, and just barely. Because while another state flipped to Trump, the margin in the state needed to flip the balance back to him is less than it was before.

Each of these views shows a different way of looking at the race. If I had to pick one at the moment, I'd choose the probabilistic win odds, because it best incorporates all of the various factors at play. But all of them still show something worth tracking.

Now, a quick review of trends in each of the swing states with updates this time around. (I'll skip the states that are not really in contention.)

There is no real clear direction to the movement in Florida. The last updates have been good for the Dems, but all four of these candidates are neck and neck with Trump in Florida. Florida can't get enough of being a state living right on the knife's edge.

Georgia has been very sparsely polled.

The first few polls showed it moving much further in the Democratic direction than the historical average. The latest results inch back toward the red. But Georgia is a state to keep a careful eye on. At the moment, it is clearly in contention.

The historical average in Michigan has been pretty blue, but the most recent polls have shown that 2016 (a narrow 0.2% Republican win) may not have been an aberration. All four of these candidates are showing close races at the moment, with Buttigieg losing to Trump, and the other Democrats holding on to narrow leads.

The trends since the summer have been toward the Republicans, but the most recent polls have gone the other way, so the next releases will be critical to watch, as we will see if the state starts moving back to the blue, or stays in swing-state territory.

Arizona is almost the opposite of Michigan. A historically red state, where the early polls pulled things into the disputed zone, but some of the more recent results have started to move the averages back, at least for Sanders and Biden. This is another state to watch very carefully.

Wisconsin started out with a historical average of Weak Democrat. 2020 polls have shifted this to Weak Trump for all four of these Democrats. The most recent polls make it look like this movement may have plateaued, but it is too early to tell.

Iowa's historical average was Weak Democrat, now it looks like Weak Trump, but it is still close enough to be in contention.

And Nevada. Warren and Buttigieg are just barely losing to Trump. Sanders and Biden are winning by a bit larger margin, but still close.

That's it for the state by state updates this time.

Finally, I have one more thing to highlight before closing.

As I write this, there are just over two weeks until the Iowa caucuses, which are traditionally the start of the delegate race for both parties. I was planning on opening up the 2020 Delegate Race part of Election Graphs with the Iowa caucuses. But surprise surprise, as I was cleaning things up there and getting it ready for launch, I discovered that some delegates are already in motion.

No, it isn't superdelegates on the Democratic side. Due to rule changes this time around, they can't vote on the first ballot unless they mathematically can't make any difference to the outcome, so we aren't tracking them this time.

It is on the Republican side.

It turns out that on December 11th, the Hawaii Republican Party voted on delegate selection rules that just went ahead and bound their 19 delegates to Trump, bypassing any possible primaries or caucuses.

Other states have said they will do this, but Hawaii is the first state to make it official.

So Trump already has 19 of the 1277 delegates he needs to win the Republican convention.

Now, nobody expects any of the Republicans who are running against Trump to get much of anywhere. It currently seems unlikely they will even get any delegates at all.

So the graphs on the Republican side are likely to be very dull, and I probably usually won't even bother to show or mention them in these blog updates. But since this is the very first delegate update, here you go:

So out of 2552 Republican delegates, 19 have already been allocated. That is 0.74% of the delegates. Given that all 19 went to Trump, that means Trump needs 49.66% of the remaining delegates to clinch the nomination.

The next expected delegate allocation is actually also before Iowa. The Kansas Republicans will decide how to allocate their delegates at their convention which runs from January 31st to February 1st. I'm sure their choice will be a huge surprise to everyone.

And with that, the 2020 Delegate Race pageĀ is open for business!

288.8 days until polls start to close.

Is Impeachment Hurting the Dems?

Once again, too long between updates. Since the last one on November 20thĀ there have been new polls in Wisconsin (x3), New Hampshire, California (x2), Texas (x2), Arizona, Michigan, Pennsylvania, and Iowa.

If I'd been posting weekly as I had intended, there would have been a post looking at how Election Graphs win odds correlated to the popular vote polling averages at RCP and using that to measure the Democrats' Electoral College disadvantage. (Spoiler: As of right now it looks like Democrats need an approximately 6% popular vote win margin to have a 50/50 chance of winning the Electoral College.)

I also would have done a post talking about how while for us political junkies, it seems inconceivable that people don't know who at least the top five Democratic candidates are, this article in the Washington Post by Robert Griffin lays out a pretty convincing case that a large part of the differences in polling between Democratic candidates vs. Trump is STILL simply that lots of people don't know who some of these people are, something that clearly would change before Election Day if they were to win the nomination. That is obviously very important when interpreting what we see here on Election Graphs, which is 100% driven by state level general election matchup polls.

But I kind of missed talking about both those points when they were fresh. So I'll let the above suffice for now.

The main thing I want to look at today is this:

This shows the median electoral college result from the Election Graphs Monte Carlo simulations for each candidate pair.

For both Biden and Sanders there is a very clear "V" shaped pattern. (OK, if you look closely, you can see a "W", but the large scale pattern is a "V".) In the first half of this V, as new polls came in and the state averages moved from the baseline based on the 2000-2016 elections, to averages based on 2020 polls, almost every poll made Sanders and Biden look better.

Although he dropped out already, you can see a smaller scale version of this "V" pattern with O'Rourke as well.

Buttigieg doesn't show the initial portion of this V. As the initial polls came in, his results basically just stayed at about the same level as the 2000-2016 baseline. Frankly though, there was very little Buttigieg vs. Trump state level polling in this time frame though, which would explain that.

But all four of these candidates share the second half of the "V". Starting at a specific point in time, as new polling results came in, more often than not, the state averages would move away from the Democrat, and so the median electoral college results would also move the same direction.

When you look at the charts, the inflection point seems to be… well… very close to the date Nancy Pelosi announced that she was officially backing the impeachment investigation over the Ukraine issue.

There are some ups and downs, and you could argue that the best numbers for the Democrats were perhaps a little bit earlier or a little bit later, but roughly speaking, leading up to that announcement on September 24th, every week Sanders, Biden, and O'Rourke looked better in the polls than the week before, while Buttigieg held steady. After September 24th though, Sanders, Biden, Buttigieg, and O'Rourke all looked weaker in each subsequent week.

This may be a coincidence. It may just relate to which pollsters put out polls in which states during this time period. It may just be a "reversion to the mean" after a series of earlier polls were more favorable to the Democrats than was really reflected by the ground truth…

But the location of the inflection point compared to the date when impeachment moved from something a few people were talking about, to a real thing that was happening is hard to ignore. It certainly LOOKS like the impeachment efforts are hurting the Democratic candidates in state level head to head polling against Trump. State after state where the polling averages had moved from red to blue, have now slipped back into the red again.

But wait. There has been one clear omission in the discussion above.

Warren's trend line just does not match the patterns followed by the four candidates discussed above. (Neither did Harris's for that matter, but she dropped out, so we won't spend more time there.) There is no clear "V" shape like Sanders, Biden, and O'Rourke. Nor does Warren follow Buttigieg's pattern.

In fact, Warren does not show any change that looks like it coincides with impeachment events. Initially as early polls came in, she looked like she would do worse than the median based on the 2000-2016 averages. Then she started doing a little better than that. And now she's a little worse again.

The fact that the reversal in fortunes that lines up with the impeachment announcement does not seem to apply to Warren (or Harris) seems notable.Ā After all, Warren was one of the first Democratic candidates to come out strongly in favor of impeachment, and she did so strongly. If there was an impact from impeachment, why wouldn't it touch her? Perhaps even more than other candidates? This may in fact be an argument toward this movement NOT being tied directly to impeachment, but rather to something unrelated.

Without information that specifically digs into motivations rather than just candidate preferences, it is hard to say anything definitive. But the alignment certainly is suggestive. We shall see if those trends continue as the impeachment saga continues to play out.

In the mean time, we'll close out by looking at the changes in our main metrics since the last update post, followed by some of the state level charts.

Dem 20 Nov 16 Dec šš«
Biden +158 +126 -32
Sanders +88 +56 -32
Warren +50 +24 -26
Buttigieg -6 -44 -38

All four still active Democrats weakened significantly in their "median case" from the Election Graphs Monte Carlo simulations.

This Ā has not been a good month for the Democrats.

Dem 20 Nov 16 Dec šš«
Biden 99.9% 99.4% -0.5%
Sanders 95.0% 83.5% -11.5%
Warren 81.8% 67.2% -14.6%
Buttigieg 44.3% 16.5% -27.8%

Given how far ahead Biden was, his win odds are still 99%+. But the other three took pretty big hits these last few weeks.

Especially Buttigieg. Last time he was already the only candidate with a less than 50% chance of beating Trump. But now that has dropped to a paltry 16.5%.

Dem 20 Nov 16 Dec šš«
Biden +210 +178 -32
Sanders +118 +58 -60
Warren +48 +14 -34
Buttigieg +6 -86 -92

Using the older and simpler "expected case" where every candidate simply wins every state where they lead the polls, you see similar across the board drops to what you see in the "median case" from the simulation, but the drops are even more dramatic.

Dem 20 Nov 16 Dec šš«
Biden +4.4% +4.3% -0.1%
Sanders +1.8% +1.0% -0.8%
Warren +0.6% +0.6% Flat
Buttigieg +0.2% -1.3% -1.5%

For the tipping point, which measures how much of a gain would be needed to flip the electoral college winner if that gain occurred uniformly across all states, Warren manages to stay flat, but the other three Democrats get weaker.

Finally, presented without additional commentary, the updated state charts in each of the states with new polling. You'll notice the recent swing toward Trump occurs in almost every state.

The news is coming hot and heavy these days. Iowa is now less than 50 days away. Things will develop quickly. Stay tuned.

323.6 days until polls start to close.

Goodbye Blue Texas

It has once again been longer than I like, but it is time for another post.

Since the last update, there have been new polls in Michigan (x3), Nevada (x2), Texas (x2), Arizona (x2), Pennsylvania (x3), Florida (x2), North Carolina (x3), Wisconsin (x2), Iowa, Georgia (x4), and New Hampshire.

That is a lot. Sorry about that. Oops.

The most striking individual state result is that after peaking in September with three of the top six Democrats leading Trump in the Texas averages, and two more getting close, Texas has been moving back toward Trump.

As of now, none of the six most polled Democrats lead in Texas, and only three of those keep Trump's lead to less than 5%. And one of those (O'Rourke) has already dropped out of the race, leaving only Sanders and Biden still making it close.

Converting this to win odds, Biden has a 30.1% chance of winning the state (if the election was today), and Sanders has a 25.0% chance of winning.

None of the rest (except O'Rourke, who is out) is above 5%.

So Texas is reverting to form. It may be closer than it has been in previous years, but at least for the moment, the Democratic hopes for a blue Texas seem to be fading.

I'll go over other states with new polling at the end of the post, but first, a look at four ways of looking at the changes in the national summary since the last post.

O'Rourke vs. Trump is now in the top six best-polled candidate combinations (replacing Sanders vs. Pence). But since O'Rourke dropped out, we will leave him out and only look at the top five for now.

I haven't done posts showing the update-to-update comparisons for the older "categorization method" before, but since that used to be the bread and butter of Election Graphs, let's start there.

Dem 1 Nov 20 Nov šš«
Biden +254 +210 -44
Sanders +190 +118 -72
Warren +38 +48 +10
Harris +20 +20 Flat
Buttigieg +6 +6 Flat

In thisĀ "expected case" view, where every candidate wins every state where they lead in the poll average, both Sanders and BidenĀ have lost ground.

Warren improves her position a little.

Harris and Buttigieg are flat.

Dem 1 Nov 20 Nov šš«
Biden +5.3% +4.4% -0.9%
Sanders +4.7% +1.8% -2.9%
Harris +1.4% +1.4% Flat
Warren +0.3% +0.6% +0.3%
Buttigieg +0.6% +0.2% -0.4%

Looking at the tipping points, which is analogous to the popular vote, but adjusted for the structure of the electoral college, once again, Warren is the only Democrat who is improving.

Harris is flat.

Biden, Sanders, and Buttigieg all lose ground to different degrees.

Note that while for a short time, Biden had a tipping point greater than 5%, meaning he could win using only states where he led by more than 5% and didn't even need any swing states. That is no longer true.

Now all five of these Democrats have tipping points indicating that they need to win at least some tight states to win.

Now, moving on to the more elaborate probabilistic model I look at a bit more these days…

Dem 1 Nov 20 Nov šš«
Biden +184 +158 -26
Sanders +124 +88 -36
Warren +36 +50 +14
Harris +8 +12 +4
Buttigieg -4 -6 -2

This view shows the "Median Case." The median case is the electoral vote margin in the exact middle of the 1,000,001 simulation runs done for each candidate combination when sorted by the margin. About half the time, the Democrat does better than this. About half the time, they do worse.

Warren and Harris both improve a bit. Biden, Sanders, and Buttigieg all lose ground.

Note that while in the classification view, all five Democrats lead Trump, in the probabilistic view, Buttigieg's median case is actually to lose.

But we need to look at probabilities, not the single "median case" estimate. You should not think that since a candidate is ahead or behind on the median case, that maps to winning and losing.

For instance, Buttigieg's median case is a six electoral vote loss to Trump. But if you look at the 2Ļƒ range,Ā that is the range of outcomes that you would expect to occur 95.45% of the time; you get a range from Buttigieg winning by 92 electoral votes to Trump winning by 90 electoral votes.

There is a huge range of possibilities. It isn't just "Trump is ahead in the median case, so he wins."

So time to look at the win odds…

Dem 1 Nov 20 Nov šš«
Biden 100.0% 99.9% -0.1%
Sanders 98.3% 95.0% -3.3%
Warren 73.1% 81.8% +8.7%
Harris 54.6% 58.2% +3.6%
Buttigieg 46.0% 44.3% -1.7%

The trends above, which cover just under three weeks, show Warren and Harris improving, while Biden, Sanders, and Buttigieg slip back.

But looking back a bit farther, we can see some overall trends going back to September.

Biden continues to be pegged at a 99%+ chance of winning. His lead in some states has slipped, but his overall margins are high enough that this hasn't yet started to impact his chances of winning.

Sanders never had as big a margin lead as Biden, so as some of those states slipped back toward Trump, you see a more significant impact on his odds of winning.

Harris and Buttigieg have never done all that much better than a coin flip against Trump, peaking at around a 70% chance of winning. But since September, they have both dropped significantly, with Buttigieg now only at a 44.3% chance of winning, and Harris only at 58.2%.

The only candidate consistently improving over the last few months has been Warren. She bottomed out at only a 41.7% shot of winning in June, and while there have been ups and downs, the trend is clearly in Warren's direction.

We will, of course, see if that lasts. As can be seen by the spike toward Trump in June, trends can reverse quite quickly.

Now, besides Texas, here are a few additional states where there are trends worth noting. (Since so many places had new polls, I'll skip a few where there is less to comment on.)

No clear trends in Florida except to note that it is an exceptionally close race no matter which Democrat you match up against Trump. As has been usual for the last few presidential races, Florida is right on the line. And it is big. So it makes a huge difference.

The general trend in Pennsylvania, Michigan, and Wisconsin over the past few months has been for Democratic leads to decrease.

In Pennsylvania, there is no Democrat with more than a 5% lead, and Warren (and O'Rourke) are both slightly behind.

At this point, only Biden has a lead higher than 5% in Michigan.

In Wisconsin, all the Democrats still lead, but none by more than 5%.

These are, of course, the three states that gave Trump his victory in 2016. At the moment, they are all looking to be close battlegrounds once again.

The people who say that the Democratic nominee needs to pay close attention to these states are certainly not wrong.

And at the moment, the Democrats seem to be slipping in all three.

Pollsters have not paid as much attention to Georgia as I would like. But there have been a bunch of polls in the last few weeks and they show aĀ competitive state, which is a significant change from the historical average.

The poll average now shows Biden and Sanders ahead, with Warren, Harris, and Buttigieg all bringing Trump's lead under 5%.

(O'Rourke has never been polled in Georgia, and now that he has dropped out, probably will never be. Sniff.)

Although Biden has reversed a bit recently, overall Sanders, Warren, and Biden are making North Carolina a narrowly fought battleground.

Harris and Buttigieg, while they are still keeping Trump's lead under 5%, do not seem to be gaining any additional ground lately.

Arizona has also been moving toward the Democrats. At least for Sanders, Warren, and Biden. Warren and Biden actually are slightly leading. Sanders brings Trump's lead under 5%.

Harris and Buttigieg, on the other hand, are not making things much closer than the historical 7.6% average Republican margin in the state. Just as in North Carolina, they lag behind the stronger Democrats.

So Trump is gaining in Texas, Pennsylvania, Michigan, and Wisconsin.

But the Democrats are gaining in Georgia, North Carolina, and Arizona.

As we get closer, things will heat up; there will be lots more polls and more movement.

Are we having fun yet?

349.7 days until polls start to close on election night.

Enter Pence?

Since last week's update,Ā there have been new polls in Michigan, Ohio, and Wisconsin.

First of all, I should mention that while the 2020Ā Electoral CollegeĀ page on Election Graphs lets you pick any Democrat and any Republican that has been polled in the 2020Ā cycle, here on the blog, we restrict ourselves to talking about the six "best polled" candidate combinations. I use a metric for this thatĀ is a weighted average of how far back in time the "five poll averages" go in each state. The weighting gives low margin states more influence in the metric than places where one candidate is far ahead.

Up until now, this had been six different Democrats vs Trump. In mid-SeptemberĀ though, SurveyUSA did a poll of California that included Pence and Haley as potential Republicans in the general election too. And this last week, Emerson included Pence in a poll of Ohio.

This is pretty sparse polling, but it happened to make the new Sanders vs. Pence polling average in Ohio very close to a tie, which because of the way my metric for "best polled" works, increases the Sanders vs. Pence poll quality up higher than it probably deserves, and Sanders vs. Pence bumps O'Rourke vs. Tump off of my top six.

I suspect this will not last, but for now, I'm looking at Biden, Sanders, Warren, Buttigieg, and Harris vs. Trump… and Sanders vs. Pence.

Within these candidate combinations, the only change in the categorization model was Ohio flipping from just barely Trump, to just barely Sanders:

The current average here includes three actual 2020 polls, plus the 2008 and 2016 elections, ending up with a 0.2% Sanders lead. Now, this is one of those zones that is a bit different. Based on the historical performance of Election Graphs averages, a 0.2% Democratic lead only translates into a 47.8% chance of the Democrat winning.

The categorization model doesn't care about that, though. Ohio is now on the blue side of the centerline for Sanders, so the "Expected Case" includes him winning Ohio. Sanders now leads in this "everybody gets all the states where they lead in the average" case by 202 electoral votes.

I've been spending a lot of time on these blog posts lately on the probabilisticĀ model, and I'll get to that in a second, but first a quick look at the expected cases for all six of the best-polled candidate matchups in terms of the categorization model:

Biden leads Trump by 242 electoral votes. Sanders now leads Trump by 202 electoral votes. Every one of the other combinations is a close race. The only Democrat losing is Warren, who falls short by 20 electoral votes.

Flipping back to the probabilistic view, which takes into account all the changes in all three states that got polls this week, not just the one category change, we see this:

Dem 29 Sep 6 Oct šš«
Biden 99.9% 99.9% Flat
Sanders 97.2% 97.3% +0.1%
Warren 66.7% 68.9% +2.2%
Buttigieg 66.5% 66.5% Flat
Harris 64.0% 64.0% Flat

Of these five, only Biden, Sanders, and Warren received new results this week. Nothing new for Buttigieg or Harris.

But let's not forget Sanders vs. Pence. Based only on the results of the last five presidential elections, this stood at a 68.1% chance of a Sanders victory. The earlier California poll had not changed this at all. Ā But adding the new Ohio poll to the average brings Sanders up to a 72.8% chance of beating Pence.

Let's also look at how the median electoral college result for these candidate matchups have changed in the last week:

Dem 29 Sep 6 Oct šš«
Biden +166 +170 +4
Sanders +112 +114 +2
Warren +30 +28 -2
Buttigieg +22 +22 Flat
Harris +18 +18 Flat

And of course, Sanders vs. Pence. Ā The result based only on the last five election results was Sanders +22. The new polling moves that to Sanders +28.

And that's it for this week.

393.7 days until polls start to close.

Some Dems Up, Some Dems Down

Since last week's update,Ā there have been two new polls in Texas, and one each in New Hampshire, Wisconsin, Michigan, and Pennsylvania.

For the six most polled Democrats against Trump (Biden, Sanders, Warren, Buttigieg, Harris, and O'Rourke) this week saw the following category changes:

  • Biden vs. Trump state category change: WI has moved from Strong Biden to Weak Biden
  • Sanders vs. Trump state category change: MI has moved from Strong Sanders to Weak Sanders
  • Warren vs. Trump state category change: PA has moved from Weak Warren to Weak Trump

Looking at how this impacted the national numbers:

In the "Expected Case" where every candidate wins every state they are ahead in, Pennsylvania moving from slightly Warren to slightly Trump means that Warren now only has a 12 electoral vote margin in this scenario.

Biden's lead dropping below 5% in Wisconsin, and Sander's lead dropping below 5% in Michigan meanwhile, improves Trump's "Best Case" (where he wins not only all of the states where he is ahead but also all the ones where he is behind by less than 5%) against both candidates.

As these five states moved around, several tipping points moved as well.

  • Sanders vs. Trump tipping point change: Sanders by 1.3% in FL -> Sanders by 1.9% in TX
  • O'Rourke vs. Trump tipping point change: O'Rourke by 2.1% in TX -> O'Rourke by 1.8% in TX
  • Biden vs. Trump tipping point change: Biden by 4.9% in VA -> Biden by 4.6% in WI

The tipping point changes already make it clear that this was a mixed week. Some Democrats improved their positions against Trump; some moved in the opposite direction. ThisĀ mix in the situation exists despite all of the actual category changes being in Trump's direction.

The movement within categoriesĀ that starts to be shown by the tipping point is something we can see even better if we switch to the probabilistic simulation view:

Dem 8 Sep 15 Sep šš«
Biden 99.9% 99.8% -0.1%
Sanders 95.8% 96.9% +1.1%
O'Rourke 80.0% 80.8% +0.8%
Warren 71.1% 69.0% -2.1%
Buttigieg 67.1% 67.0% -0.1%
Harris 64.3% 65.7% +1.4%

There were a lot of mixed results in a lot of states this week. But when you balance it all out in terms of the odds of winning in the Electoral College:

  • Harris, Sanders, and O'Rourke strengthened against Trump
  • Warren, Biden, and Buttigieg weakened against Trump

Another way of looking at this is the median margins in the Monte Carlo simulations for each of the candidate combinations:

Unlike the categorization "Expected Case" view, where Harris narrowly loses to Trump, all six Democrats lead Trump in the probabilistic "Median Case."

Warren, Buttigieg, and Harris all lead by 30 or less electoral votes, though. In electoral vote terms, that is a very tight race. Any state with more than 15 electoral votes slipping to the other side of the centerline would switch the outcome.

O'Rourke, Sanders, and Biden, each, in turn, have more of a margin than the candidate before, so additional buffer. They can afford for more to go wrong before they lose.

Now, let's look at each of the five states that got polled this week.

Of the two polls in Texas, one matched other recent surveys and was mostly favorable to the Democrats. The other showed clear Republican leads.

The net impact of the two polls on the averages was that Biden, Sanders, Warren, and Harris continued improving in Texas, while Buttigieg and O'Rourke got a little weaker.

You do get one piece of oddness, though. I use the methodology I described in my Polling Error vs. Final Margin postĀ to translate margins into odds of winning. When I use the straight-up unsmoothed numbers from the 2008 to 2016 elections, there are a few places where the relationship between the polling average and the win odds are not monotonic.

ThisĀ behavior means that even though O'Rourke's polling average dropped from a 2.1% lead to a 1.8% lead, my computed "odds of winning Texas" for O'Rourke INCREASED from 66.4% to 68.2%.

Now, I could have smoothed the handful of places where this non-monotonic behavior occurs out of existence. But I chose when I first set up the odds based view to use the numbers that came straight out of my analysis of the previous election results without any further manipulation.

Given the historical data and the methodology I used, a 1.8% Democratic lead is indeed slightly more likely to win than a 2.1% Democratic lead. Of course, this does seem a little crazy and is quite possibly just an example of overfitting.

But it isn't a huge difference and occurs at only a few specific margin zones, so I'll leave it be.

We still end up with a situation where three of the six Democrats are leading in Texas though, and another two make it close.

Texas continues to be one of the most important states to watch.

Sanders improved slightly in Pennsylvania.

Biden's lead deteriorated significantly.

Warren lost her lead to Trump.

The poll did not include the others.

Biden, Sanders, and Warren all weaken against Trump in Michigan with this week's update.

The poll did not include the others.

Warren got stronger in Wisconsin.

Biden and Sanders got weaker.

The poll did not include the others.

Biden, Sanders, Warren, and Harris all got weaker in New Hampshire with the latest polling.

The poll did not include Buttigieg or O'Rourke.

And that's it for this week's update.

415.6 days until polls start to close.

Missouri, Michigan, and Utah

Since last week's update,Ā there has been new polling in Missouri, Michigan, and Utah.

The only category change coming out of this was that in a Harris vs. Trump race Missouri moves from Strong Trump (a 5% to 10% Trump lead) to Solid Trump (a greater than 10% Trump lead).

Looking more generally, the Democrats improve their leads in Michigan, Missouri looks redder than it did before, and Utah is still bright red but a little less so.

Looking at a national level, Harris, Warren, and Sanders improve their win probabilities against Trump in the probabilistic view. Everyone else is flat.

Dem 25 Aug 1 Sep šš«
Biden 99.9% 99.9% Flat
Sanders 95.5% 95.7% +0.2%
O'Rourke 80.0% 80.0% Flat
Warren 71.0% 72.6% +1.6%
Harris 65.8% 67.9% +2.1%
Buttigieg 67.1% 67.1% Flat

Now, let's look at the three states with new polls:

Biden and Sanders improve their polling averages noticeably with this new polling from EPIC-MRA. Warren and Harris also improve slightly. EPIC-MRA did not poll Buttigieg and O'Rourke.

Bottom line, Biden and Sanders continue to be in a position to easily win Michigan. The others are all leading, but narrowly, and the state would very much be in play.

This is the first 2020 polling for Missouri.Ā RRGĀ polled Biden, Sanders, O'Rourke, and Harris. It is actually an old poll from April, but it was new to Election Graphs this week.

In all four cases the averages moved in the Republican direction.

This first set of Missouri polling ranged from an 8% Trump win (against Biden) to a 16% Trump win (against Harris). Ā Only one poll so far, but it isn't looking like Missouri is one of those red states that is getting less red.

Utah, on the other hand, does look like a red state that might be getting a little less red. Maybe.

The first 2020 polling for Utah is from Y2 Analytics, and the sample sizes on their head-to-head matches are extraordinarily small (from 140 to 153), so you should take them with a massive pile of salt.

The average of the margins in Utah from 2000 to 2016 is a 36.1% Republican victory. Utah has not gone Democratic since Lyndon Johnson's 1964 landslide over Barry Goldwater. Utah is a VERY red state.

This new poll shows a range of results in our top six candidates from Sanders winning by 6%, to Buttigieg losing by 20%. Biden and Warren were within the margin of error of winning too.

Even that Buttigieg loss does better than the historical average. But Sanders WINNING? That is a very surprising result for Utah.

And, while he is not in the six most polled candidates against Trump, so we wouldn't usually mention it, Y2 also polled Booker against Trump, and had Booker beating Trump by 12%!

Frankly, these Utah results are tough to believe. It would take a lot more than one poll to make it reasonable to think that Utah was competitive for ANY of the Democratic candidates, let alone that one of them was leading by double digits.

Which is of course why you look at averages, not at individual polls. This Y2 poll when averaged in with the 2004 to 2016 elections, is enough for Election Graphs to put the poll average for the best of our six Democrats (Sanders) at a 26.8% Trump lead, which still translates into a 100% chance of Trump winning Utah.

(And for the record, Trump would lead Booker by 25.6%, also a 100% chance of Trump winning.)

If we get more Utah polls showing a close race, maybe this will change. But for the moment the weight of the historical averages means we treat this Y2 poll with extreme skepticism, and Utah remains a very very Red state.

And that's where things stand at the beginning of September.

429.2 days until polls start to close.

Whoa, Look at Texas

Since the last updateĀ (not counting the update about new graphs) there have been new polls in Maine (All), South Carolina, Ohio, Michigan, Texas, and North Dakota.

Of those, only Texas and Michigan resulted in category changes for any of the six best-polled candidate pairs.

In Michigan, Buttigieg moved from a 6.4% lead to a weak 2.8% lead in the Election Graphs average.

In Texas, Sanders, Warren, and O'Rourke pulled Trump's lead down under 5% into the "weak" category in the Election Graphs average. Biden had already gotten there back in June.

Texas is the headline.

Trump's lead in Texas in the Election Graphs average is now down to under 5% for four of the six most polled Democrats against him. Only Buttigieg and Harris lag. But even they are trending stronger as more polls come in.

None of the averages show a Democratic lead in Texas. That would be seismic. However, at this point five of the six Democrats have at least one poll showing them ahead in Texas. (The exception is Buttigieg.)

Nobody would call Texas blue at this point. But it is trending purple. We have enough polls for enough candidates showing only narrow Republican leads (or even Democratic leads) to say that it looks competitive.

Now, what does competitive mean? Let's look at the "odds" view, where we use the historical performance of final Election Graphs averages to convert the poll margins into odds of victory:

Democrats making Texas "close" essentially means Trump has a noticeably less than 100% chance of winning.

Of these six Democrats, Buttigieg is weakest… Ā with Trump still having a 99.2% chance of winning the state.

Biden is strongest, but Trump still has a 64.6% chance of winning Texas against him.

Now, that means Biden has a 35.4% shot, which is remarkable given where Texas has been in other cycles. But Trump is still favored.

Now is the time to once again mention that Election Graphs does not model how the race evolves. These "odds" are static snapshots in time. "If the election was today." The election is not even remotely today. Polls can swing wildly in just a matter of weeks, let alone the 15 months we still have until the general election.

This "closeness" in Texas could evaporate long before we get to November 2020. Or it could turn into a Democratic lead.

But it is clear that Texas is a state to watch, and Republicans will need to play defense there, and not take it for granted, as has often been the case in recent cycles.

Now, the national picture, where all the caveats above also apply:

This batch of polls changed the "Best Case" scenarios for Sanders, Warren, and O'Rourke in the category based ranges (theirĀ best cases now include winning Texas). But the "Expected Case" and "Tipping Point" did not change.

However, the new probabilistic based simulations do show changes worth reviewing.

This first chart shows the "median case" of the simulations, the spot where half the time the Republican does better, and half the time the Democrat does better.

Biden doing better than the rest of the pack stands out clearly. His median case is a 126 electoral vote margin over Trump. To put this in historical context, this would exactly match Obama's 2012 margin over Romney but be quite a bit less than Obama's 2008 margin over McCain.

Sanders also breaks out from the pack, doing considerably better than the other Democrats.

Both Biden and Sanders have improved their median positions significantly over the last few weeks covered by this batch of new polls.

Meanwhile, Warren, Buttigieg, O'Rourke, and Harris stay within a zone maintaining only small electoral college margins in the median case.

So, switching from looking at margins to looking at chances of winning:

Biden is pegged near the top right now. 99.6% chance of victory over Trump. There isn't that much room to improve, although weaker polls could certainly knock him off this pedestal.

Sanders clocks in second at an 89.0% chance of beating Trump.

Looking at the others, while they do have the upper hand on Trump, if this were election day, it wouldn't be fair to say it was anything other than "too close to call" with odds ranging from Warren at 58.2% to O'Rourke at 64.7%.

Election Graphs didn't have a probabilistic view in 2016, but the median "chance of Trump winning" from the sites that did was 14% going into Election Day. Only Biden and Sanders push Trump below that line at the moment.

So how have things been changing?

Comparing the odds of the Democrat winning from theĀ update on June 23rdĀ to where things stand now, we see this:

Dem 23 Jun 3 Aug šš«
Biden 99.4% 99.6% +0.2%
Sanders 86.0% 89.0% +3.0%
Buttigieg 65.5% 62.9% -2.6%
Harris 62.3% 62.2% -0.1%
O'Rourke 50.5% 64.7% +14.2%
Warren 53.2% 58.2% +5.0%

The stand out is, of course, O'Rourke. His improvement is almost all due to his performance in the latest Texas poll, which was better than all other Democrats, and significantly better than his previous polling in the state as well. So he adds to his chances of winning Texas, which while still under 50%, is enough to boost his chances of taking the whole thing significantly.

Warren and Sanders also improved a bit. Buttigieg dropped a bit. And Biden and Harris are essentially flat.

Finally, a quick preview of a new chart type coming soon to Election Graphs:

It is the equivalent of the Electoral College trend chart based on the straight-up categorization of states based on who is ahead, but with the results of the probabilistic modeling.

The dark line represents the median electoral college result in the simulation. Then the bands represent result ranges at different levels of probability. The deeper the shade, the more likely the result.

This is a visual representation of the single candidate time series of the probabilistic summary now on the comparison page:

The text summary will also, of course, be added to the candidate national summary pages once I get a chance.

I also added little circles in a lot of the time series charts to highlight the current values better. I think it makes the charts clearer. Hope you like them.

In any case… 458.1 days until polls start to close. Stay tuned!

Most Dems improve against Trump while Buttigieg weakens

Since the last update,Ā there have been new polls in Kentucky, Wisconsin, Michigan, Pennsylvania, Florida (x2), and North Carolina.

With this update, Buttigieg vs. Trump has now replaced Harris vs. Trump in the "five best-polled candidate combinations" that I'll spend time on in these posts. The new list is Biden, Warren, Buttigieg, Sanders, and O'Rourke all paired against Trump.

With this latest batch of polls, we have the following changes:

National:

  • Trump best case vs. Warren has changed: Warren 214 to Trump 324 -> Warren 204 to Trump 334
  • Warren vs. Trump tipping point change: Trump by 0.1% in VA -> Warren by 0.5% in FL
  • Warren vs. Trump expected case change: Warren 266 to Trump 272 -> Warren 295 to Trump 243
  • Buttigieg vs. Trump tipping point change: Buttigieg by 1.1% in IA -> Buttigieg by 0.6% in PA
  • Sanders vs. Trump tipping point change: Sanders by 1% in IA -> Sanders by 1.3% in FL
  • Sanders vs. Trump expected case change: Sanders 272 to Trump 266 -> Sanders 301 to Trump 237
  • O'Rourke vs. Trump tipping point change: Trump by 0.5% in FL -> Trump by 0.3% in FL

Wisconsin:

  • Warren vs. Trump state category change: WI has moved from Strong Warren to Weak Warren

Florida:

  • Sanders vs. Trump state category change: FL has moved from Weak Trump to Weak Sanders
  • Warren vs. Trump state category change: FL has moved from Weak Trump to Weak Warren

OK, now on to the graphs… national first:

In the expected case, Warren and Sanders improve.

Notably, Warren moves from losing to winning with this update.

Biden continues to do the best of the five Democrats, while O'Rourke does worst.

In the tipping point Warren, Sanders, and O'Rourke improve, while Buttigieg weakens.

Once again, you can see Warren crossing the center line to the winning side of the field.

And once again Biden does best, while O'Rourke does worst.

Now let's look at all of the states that had new polls in this batch:

In Florida, O'Rourke and Buttigieg are losing to Trump. Biden, Warren, and Sanders are beating him. As usual, Biden is doing better than the other Democrats. But every single matchup here is close. As usual, Florida is a battleground state.

Biden has a healthy lead in Pennsylvania. O'Rourke is behind Trump. All the rest of these five Democrats are in the lead over Trump, but they have narrow edges.

In Michigan, Biden is doing best. Warren is doing worst. Strong leads for Biden, Sanders, and Buttigieg. Warren and O'Rourke ahead by narrower margins. But all five leading Trump.

Biden is the only Democrat leading Trump in North Carolina. But all five would make it a close race. North Carolina is definitely in play at the moment.

In Wisconsin, Biden is doing best, O'Rourke is doing worst. Biden and Sanders have strong leads. Buttigieg, Warren, and O'Rourke are only weakly ahead. But all five lead Trump.

Kentucky is very very solidly red. With the very first Kentucky poll of the cycle, it looks like it may be even redder this time around than the average of the last five elections.

OK, finally, the odds based view of the national race. I haven't managed to make this view live on the site with graphs and all yet, but I'll at least provide updates here.

Democrat Dem Odds Trump Odds Tie Odds
Biden 99.4% 0.4% 0.1%
Sanders 86.0% 13.2% 0.8%
Buttigieg 65.5% 33.2% 1.2%
Warren 53.2% 44.9% 1.9%
O'Rourke 50.5% 47.8% 1.7%

For those missing Harris, since she dropped off my top five, she's now at a 62.3% chance of winning.

It remains striking what a vast range there is between Biden on the one end of this spectrum and O'Rourke on the other.

As always, the caveat that things can and will change, but if the election was today, Biden looks about as close to a sure thing as you can get (much stronger than the median odds based view Clinton had, which was at about 86% on election day), while meanwhile, O'Rourke looks like a coin toss.

If this is primarily due to name recognition and the main deciding factor for voters is simply Trump vs. non-Trump, you should see the divergence between various Democrats reduce over the next few months as people get to know some of the lesser-known Democrats.

If on the other hand, these kinds of differences persist as we get closer to the Iowa caucuses, then there are lots of people out there where the choice of Democrat does indeed influence them on their final vote. In this case, "electability" becomes a valid criterion for Democrats to consider when making their choices in the primaries and caucuses.

3.1 days until the first Democratic debate.

499.1 days until polls start to close on Election Day 2020.

Trump Internal Polls All Good News For Biden

Since the last update,Ā there have been polls in North Carolina, New York, Michigan, Pennsylvania, Wisconsin, Florida, Texas, Virginia, Maine (All), Minnesota, Iowa, Ohio, and Georgia.

Now, most (but not all) of these are internal Trump campaign polls that were leaked and reported on by first ABCĀ and then NBC. The full internal polling reportedly included 17 states and matchups against multiple Democrats, but the leaks so far only includeĀ Biden versus Trump results in 12 of them. Because this is a leak of internal polls and not "regular polls," I tweeted a series of notes on these polls, that I will repeat here:

  • 1st: Some aggregators automatically exclude internal polling because of potential selective release bias, etc. I default to including as much as possible. So they are reflected on Election Graphs.
  • 2nd: I'm going with ABC on the field dates, not NBC. ABC reports March 15th to March 28th, which is precisely two weeks. NBC reports March 13th to March 28th, which includes two extra days. These almost certainly are the same batch of polls though.
  • 3rd: ABC and NBC differ slightly on their reports of the results in Pennsylvania, Wisconsin, and Florida. In these cases, I will include both, but weighted as half polls, just as I do when a pollster reports results in multiple ways (with & without 3rd parties, registered vs. likely voters, etc.)
  • 4th: For some states this leak only includes margins. Election Graphs only uses margin in calculations, but it displays & reports candidate results too. For the instances where we only have leaked margins, I will log the polls such that Trump-Biden=Margin and Trump+Biden=100%.
  • 5th: If a range of possible margins is reported rather than a specific margin, I will log these as the center of that range.
  • 6th: If more detailed leaks become available, I will adjust how these polls are recorded to reflect any new information.

With those caveats, here are the status changes that occurred as a result of this batch of polls. After that, we'll start looking at the graphs.

All of these changes are for the Biden versus Trump matchup.

State Level:

  • Florida (29 EV) has moved from Weak Trump to Weak Biden
  • Virginia (13 EV) has moved from Weak Trump to Weak Biden

National Level:

  • Expected case change: Biden 299 to Trump 239 -> Biden 341 to Trump 197
  • Tipping point moves from Biden by 1.9% in NC to Biden by 3.4% in ME-CD2.

We'll look nationally first, then the states that changed categories, then a brief look at the locations that did not. Finally, I'll report on what all this does to the Monte Carlo simulation of the national race.

Keep in mind that all of the leaked internal polls were in the field back in March, so they are older data, and will change not just the end of the lines in the charts, but the shape of those lines over March, April, May, and June.

Rather than going graph by graph, here is the whole summary block from the Biden versus Trump page. The two charts on the right show a clear trend toward Biden.

Now, we are still at the stage where most states don't have five polls yet, so we are filling in data based on previous general election results when constructing state averages. So it is crucial to note that this "movement" is mostly not representing changes in public opinion yet, but rather is reflecting the increasing knowledge over time of what Biden vs. Trump looks like specifically, rather than a generic Democrat vs. Republican based on the average historical results from 2000 to 2016.

So the trend may not represent people flocking to Biden over the last few months, but instead, it shows that the more polls we get in more states, the stronger Trump looks against Trump.

Also important to note that while the "expected case" now has Biden winning by 144 electoral votes, a month before the 2016 election, the "expected case" was a 154 electoral vote win for Clinton. By election day that had slipped to only an eight electoral vote lead. And of course, Trump won by 77 electoral votes. The "expected case" can move very quickly, and does not give the whole picture anyway.

Similarly, the tipping point is now a 3.4% Biden lead, while less than two weeks before the election, Clinton had a 5.4% tipping point lead. That evaporated to 1.6% in the last two weeks, and the actual tipping point in the election was an 0.8% Trump margin.

So Biden looks formidable, but Clinton looked even stronger at times.

Also, things can move very quickly even in two weeks, let alone 506 days.

We have a long way to go.

OK, now the two states that changed categories in this update:

Including the two slightly different versions of the Trump internals leak as one averaged result, there have only been three Biden vs. Trump polls in Florida so far. And they cover a vast range. The average (including 2016 and 2008 to round things out) is a 1.0% Biden lead.

ThisĀ lead translates into about a 55.6% chance of a Biden win, and a 44.4% chance of a Trump win.

As usual, Florida is a swing state.

The Trump internals leak is the very first 2020 polling for Virginia. From 2000-2016, there had been 3 Democratic wins, and 2 Republican wins. The average had been a very narrow 0.1% Republican lean for Virginia.

With this new poll, the 8.0% margin Republican win from 2000 slips off the average and a 17.0% lead for Biden enters. That's quite a swing! As a result, the current pollĀ average moves to a 4.9% Biden lead, which translates into a 90.9% chance of winning the state.

And now, quickly, the other states with Biden vs. Trump polls in this update that did not change category:

Trump leads in Texas by only 1.0%, which translates into a 66.4% chance of victory if the election was today. Trump is still a favorite in Texas, but that this is even a question is striking in and of itself.

Biden leads by 8.5% in Pennsylvania. That would be a 99.1% chance of winning. (If the election was held today, which of course it is not.)

Biden leads by 0.9% in Ohio. 55.3% chance of winning the state.

The Trump internal poll was the first Biden vs. Trump polling for Georgia. It shows Biden with a significant lead, but given the historical Republican wins in Georgia, it will take a few more polls showing a Biden lead before the average goes there. For now, the average sits at a 5.8% Trump lead, which is a 98.1% chance of a Trump victory.

Biden leads by 7.1% in Michigan. 98.8% chance of winning.

Biden leads by 1.9% in North Carolina. 67.0% chance of winning.

The internal Trump poll is the first Biden vs. Trump polling in Minnesota. Biden is now leading by 7.4%, which would be a 99.1% chance of winning.

Biden leads by 7.5% in Wisconsin. 98.3% chance of winning.

Iowa is currently the closest state in the Biden vs. Trump spectrum of Election Graphs averages, with Trump squeaking out an 0.1% lead, which translates into a 55.1% chance of a Trump win.

The Trump internal polling was the very first polling on Maine. Biden is looking stronger than the historical average for Maine general elections. Biden is leading by 11.9%, which translates into a 100.0% chance of winning the state.

There were also polling results in New York (from Spry, not Trump's internal polling), but only for Gillibrand and de Blasio, who aren't in our "top five matchups against Trump" list that I discuss here on the blog. It was also heavily blue New York, and the results were unsurprising.

So finally, an updated look at how where the Monte Carlo simulation puts the Trump vs. Biden race after this update. As usual:

  • ThisĀ simulation is "if the election was held today," which it is not.
  • The model uses the past accuracy of the final Election Graphs averages in the 2008-2016 elections to estimate poll-average reliability in 2020. It is always possible that polling accuracy in 2020 will differ in important ways from previous election cycles.
  • We still have very sparse polling, and many states have averages that are based in whole or in part on election results from 2000 to 2016 rather than actual 2020 polls.

OK. With that out of the way, a Monte Carlo simulation with 1,000,001 trial election runs:

  • Median result: Biden by 110
  • 1šœŽ (68.3%) range: Biden by 168 to Biden by 56
  • 2šœŽ (95.4%) range: Biden by 220 to Biden by 12
  • 3šœŽ (99.7%) range: Biden by 254 to Trump by 24

Expressing the results as win odds instead:

  • Biden win: 99.1%
  • Trump win: 0.7%
  • 269-269 tie: 0.2%

Ouch, this last set of polls, mostly the Trump internal points, really hurt for Trump. That 0.7% chance of a Trump win is down significantly from the 6.2% in the last update.

Should I repeat the caveats? The results above may look good for Biden, but it is still a long time until the election, and things will change.

Actually, they already have.

Because I had other things to do, it took me a couple of days to get this blog post done, and in the meantime, there have been new polls in five states. I'll be updating the site with the new data shortly, and will be back with another blog post if there are notable changes to mention.

503.9 days until polls start to close.

Biden makes NC blue, mixed changes in MI, and what about TX?

Not counting the post about new features, there have been new polls in Florida, North Carolina, Michigan, and TexasĀ since the last update.

For the five best-polled candidate pairs (Biden, Sanders, O'Rourke, Warren, and Harris versus Trump), there were only Election Graph status changes in North Carolina and Michigan. We'll summarize them up top, then start looking at specific graphs for more detail.

North Carolina:

  • Biden vs. Trump:
    • State category change: NC has moved from Weak Trump to Weak Biden
    • Expected case change: Biden 284 to Trump 254 -> Biden 299 to Trump 239
    • Tipping point change: Biden by 0.3% in OH -> Biden by 1.9% in NC

Michigan

  • Sanders vs. Trump:
    • State category change: MI has moved from Weak Sanders to Strong Sanders
    • Trump best case vs. Sanders has changed: Sanders 214 to Trump 324 -> Sanders 230 to Trump 308
  • Warren vs. Trump:
    • State category change: MI has moved from Strong Warren to Weak Warren
    • Trump best case vs. Warren has changed: Warren 230 to Trump 308 -> Warren 214 to Trump 324
  • Harris vs. Trump:
    • State category change: MI has moved from Strong Harris to Weak Harris
    • Trump best case vs. Harris has changed: Harris 216 to Trump 322 -> Harris 200 to Trump 338

Let's look first at Biden in North Carolina:

The election graphs average now contains 4 actual 2020 polls, plus the 2016 election results. Of the four actual Biden vs. Trump polls, three show Biden leading. Together this pulls the average back to the blue side of the fence. (It was there before for a bit, just barely, back in January and February.) Biden now leads in the average by 1.9%, which based on Election Graphs history translates into about a 67% chance of winning the state if the election was today.

Looking at a wider range of candidates, Biden continues to do significantly better than any of the other Democrats against Trump. For Michigan, three candidates changed categories, so I'll skip the individual candidate charts and move straight to the comparison chart:

The Michigan comparison chart is messy. No question about that. In these latest changes, Sanders improved his average dramatically, while both Warren and Harris slipped significantly.

Now, the range within all these candidates is from Sanders having a lead of 7.3% to Harris, who is leading by 3.9%. So a 3.4% range. Not that large, right? Well, let's look at it converted into win odds:

With an odds based view, Sanders has a 98.9% chance of winning Michigan, while Harris only has an 83.2% chance. OK, that still doesn't sound like THAT big a difference, they are both pretty high.

But if you look at itĀ as Trump's chance of winning, it goes from 1.1% against Sanders, to 16.8% against Harris. These are just the same numbers looked at a different way, but this way of looking at it makes the difference a lot clearer. Trump's chances in Michigan (based on current polling data) are much better against Harris than they are against Sanders.

A small difference in the poll averages can make a massive difference in the odds. The closer the state is, the more dramatic this impact is.

OK. The polls in the other two did not result in category changes, but we'll look at them quickly anyway.

Despite being large and usually very close, very few organizations have polled Florida so far. Of the five matchups shown here, we have two polls of Biden vs. Trump. We have one survey each for Sanders, Warren, and Harris vs. Trump. And O'Rourke vs. Trump hasn't been polled at all.

Given that, there isn't much to say about Florida yet. So far, Trump still beats all five Democrats. Biden does best. Harris does worst. But it is still very early, and we need more polls.

Ah. Texas. The most recent survey here was a Quinnipiac poll released on June 5th. That has resulted in a lot of conversation, because every Democrat they polled was within the margin of error of Trump, and Biden was beating Trump. Of course, you should never look at just a single poll. But look at the poll averages above.

The movement here does not represent changes in the opinion of Texans over the first half of 2019. What this does show are actual 2020 polls slowly taking over the average from the prior assumptions based on previous election cycles. As 2020 polls filter in, the poll averages have been rushing toward the Democrats.

None of these lines have flipped to a "Blue Texas" as of now though.

The Republicans still lead.

Looking at the odds view, only Biden has started to break out from the "extreme long shot" zone. He's now at a 30.9% chance of winning Texas.

You should still bet on Trump to win Texas, but at this point, it is already clear that Texas is looking a lot closer in 2020 than it has in previous election cycles.

Switching to the national view, a quick look at the expected case comparison:

Biden still looks best against Trump, O'Rourke looks worst against Trump.

And the tipping point:

After a brief time with Sanders having the best tipping point against Trump, Biden once again is doing best. And as with the expected case, O'Rourke looks worse.

While I don't have the statistics and graphs live on the website yet, I've started to do some offline Monte Carlo simulations of the whole country based on the state poll averages and the statistics for how well election graphs averages have done over the last three election cycles.

I think it is time to share a bit of that.

Before I present these, please remember that these are "if the election was held today" numbers, based on polling that is still very sparse.

These can and will change dramatically during the many months before the election.

First, let's look at Biden versus Trump and how it was changed by these four polls, in order by the mid-date of their field dates, which is how Election Graphs orders polls:

Timeframe Biden Odds Trump Odds Tie Odds
Before polls 83.4% 15.6% 0.9%
After FL poll 87.4% 11.9% 0.8%
After MI poll 86.6% 12.6% 0.8%
After TX poll 89.9% 9.5% 0.6%
After NC poll 93.4% 6.2% 0.4%

You can see here that each of these individual polls noticeably changed the picture for Biden versus Trump. Collectively, this was a good polling week for Biden, significantly strengthening his position.

I won't repeat the poll by poll evolution for all five candidate pairs, but it is fascinating to see how they compare at the moment.

Democrat Dem Odds Trump Odds Tie Odds
Biden 93.4% 6.2% 0.4%
Sanders 80.4% 18.4% 1.1%
Warren 63.3% 34.8% 2.0%
Harris 54.7% 43.2% 2.1%
O'Rourke 49.5% 48.8% 1.7%

It is striking how much of a difference there is between these five matchups.

There are important debates on the Democratic side about "Electability" and how it should or should not play into decisions people make about which candidate to support in the primary process.

In terms of that debate, I reiterate the caveats I stated earlier: These numbers will almost certainly change significantly over time, and we have only very sparse polling to generate these numbers.

I'll add that the Biden and Sanders advantage over the rest of the field is almost certainly at least partially due to name recognition, and as the campaign season progresses and other candidates gain visibility, this will probably fade.

But this is something to watch. And while looking at this NOW may not be indicative of much, if there is still a large spread between how the leading candidates fare by the time Democrats start voting in caucuses and primaries, it might make sense to start paying attention to odds like this as part (not all) of the decision making process.

I hope to have website features based on this sort of analysis up on the website before too long.

Keep watching.

514.2 days until polls start to close.
