Harris and Buttigieg Struggling in Trump Matchups

Apologies for the radio silence. I had been trying to post a blog update here weekly, but things got in the way the last few weeks. One of the items was the fact that my wife Brandy is running for local office, and I've been helping do things like put out signs and such. If you happen to live in South Snohomish County, Washington, take a look at her campaign site and vote! Ballots are due Tuesday! No polls for races like this, so no previews. We'll see the results when we see the results.

In any case, it is only the blog summaries that have suffered; the actual polls have continued to be updated this whole time. You can always check the 2020 Electoral College pageĀ for the current status. In any case, let's look at what has changed.

Since the last update, there have been new polls in North Carolina (x2), Ohio (x2), Virginia, Maine (All), Iowa, Minnesota, California, Florida, Wisconsin, Arizona, and Washington.

Let's look first at the changes to the national probabilistic views.

The main theme of the nearly three weeks since the last update is Harris and Buttigieg doing significantly worse in matchups against Trump.

Dem 13 Oct 1 Nov šš«
Biden +166 +184 +18
Sanders +124 +124 Flat
Warren +30 +36 +6
Harris +20 +8 -12
Buttigieg +24 -4 -28

All of the above vs. Trump. Sanders vs. Pence flat at Sanders +28.

The decline for Harris and Buttigieg is even more apparent in the win odds:

Dem 13 Oct 1 Nov šš«
Biden 99.9% 100.0% +0.1%
Sanders 98.3% 98.3% Flat
Warren 70.6% 73.1% +2.5%
Harris 68.0% 54.6% -13.4%
Buttigieg 66.8% 46.0% -20.8%

All of the above vs. Trump. Sanders vs. Pence at a 72.7% chance of a Sanders win. ThisĀ percentage is down 0.1% from 72.8% on 13 Oct, but this is just random fluctuation of the Monte Carlo model, not a real change. (There was one new Sanders vs. Pence poll, but it was in California and did not make any difference.)

Biden ticks up to 100.0%, but that is because I round. It is really 99.98% at the moment. Still, Biden is doing extraordinarily well in these state by state polls against Trump and continues to get stronger.

Note that Buttigieg is now at a less than 50% chance to win against Trump. The last time any of the most polled Democrats were under 50% was in June when Warren briefly dropped below that threshold before rebounding.

At this point, there are three tiers of Democrats against Trump.

  • Winning decisively: Biden and Sanders
  • Leading, but narrowly: Warren
  • Coin toss: Harris and Buttigieg

Next, let's look at the changes in each state with new polls to see what is driving the national results.

Starting with California since it has the most electoral votes, but you won't find any hints as to changes to the national picture here. California is very solidly blue, and nothing is changing about that.

Florida, on the other hand, has lots of electoral votes and is close. So small changes make a big difference. Harris is now 2.6% behind Trump, which translates into only having a 16.6% chance of winning the state, down from 24.2% before this update. With 29 electoral votes at stake, that makes a real difference in the overall picture.

Similarly, Buttigieg moves from a 45% chance of winning the state down to 35%.

Compare to Biden with a 2.7% lead and a 71% chance of winning.

Florida is important. Winning it is part of many paths to victory on the national level.

So when Biden and Warren make gains in Florida and lead, while Harris and Buttigieg fall further behind, it makes a difference.

No category changes, but Sanders, Warren, and Biden are clearly improving, while Harris and Buttigieg (whose lines overlap) are moving in the opposite direction. In win chance terms, Harris and Buttigieg move from a 40% chance of winning Ohio, down to only 23%.

North Carolina is a key state. It is in the "swing state" zone for all five of these Democrats against Trump.

Sanders flipped from just barely winning, to barely losing in North Carolina.

That was the only category change, but both Biden and Buttigieg weakened considerably here. Looking at how this translates into win chances, Biden goes from a 91% chance of winning North Carolina to a 68% chance. Either way, still nicely favored, although certainly by less than before.

But Buttigieg drops from a 30% chance of winning down to only about 8%. Basically, from "OK, he's behind but has a shot" to "Yeah, not impossible, but it would be a major upset if he pulled off a win."

Every Democrat improves in Virginia. The state is still significantly under polled. So far, each update makes it look bluer as real 2020 polls replace old elections in the averages.

Biden's lead moves from "strong" to "solid" in my categorization.

Sanders' and Warren's leads both improve from "weak" to "strong" in the categories.

All the polled Democrats increased their leads over the historical average margin. Washington is a blue state that is getting bluer. It is not in contention right now.

In Arizona, Warren improves a little bit against Trump, but every other combination is flat.

All of the Democrats have significant leads in Minnesota, and the new polling just increased the margins for those polled. Minnesota is not currently in play.

With this last update, Wisconsin moved from Weak Biden to Strong Biden, and from Strong Sanders to Weak Sanders.

But the most significant change was for Buttigieg, whose 4.2% lead (85% chance of winning) dropped to a 1.0% lead (56% chance of winning).

Iowa is a swing state for all candidate combinations. But with this last update, Sanders and Warren both weakened, with Sanders moving from slightly ahead to slightly behind. Biden strengthened, moving from just slightly behind to just slightly ahead. Warren drops to only a 14% chance of winning the state.

The worst Democrat in Maine (Biden) still has a 99.2% chance of winning the state. Maine (CD2) might come into play again, but Maine as a whole doesn't look like it will.

That's all the states.

Now to wrap things up by looking at the changes on the categorization view. I prefer the probabilistic view these days, but just looking at who leads where and by how much is still useful.

The expected case changes:

  • Biden vs. Trump: Biden +242 to Biden +254
  • Sanders vs. Trump: Sanders +232 to Sanders +190
  • Warren vs. Trump: Trump +20 to Warren +38

And the tipping point changes were:

  • Biden vs. Trump: Biden by 4.4% in WI to Biden by 5.3% in PA
  • Sanders vs. Trump: Sanders by 4.3% in VA -> Sanders by 4.7% in VA
  • Warren vs. Trump: Trump by 0.1% in NC to Warren by 0.3% in FL

A reminder that sometimes the "median case" in the probabilistic view can have a different leader than the "expected case" in the categorization view.

Divergence like this occurs when there are states that the leader barely leads, and there is a better chance of enough of them to make a difference flipping than there is of states flipping the other direction.

One final categorization comparison to show the three tiers of Democratic candidates against Trump that I mentioned at the start of the post. Time to look at the "spectrum of the states" for the five Democrats against Trump and compare what they look like:

The Democrats that are winning decisively:

The Democrat who is leading, but narrowly:

The Democrats whose chances are a coin toss:

And that is where we are.

367.7 days until polls start to close.

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.

The First 2020 Polls

A few days agoĀ I looked at where all the states ended up if you just look at the average results of the last few elections. No 2020 specific data.

But there have already been state level 2020 polls. Sixteen by my count. They are now all included on Election Graphs.

When I do updates here, unless there is a strong reason to do otherwise, I'm going to only discuss the five "best polled" candidate pairs. At the moment, the only Republican polled so far has been Trump. (Sorry Weld fans.) The five best polled Democrats against him right now are Biden, Warren, O'Rourke, Sanders, and Harris… in that order.

So with that out of the way, let's start looking at some graphs!

The chart above shows the "expected" electoral college result for each of these five candidate pairs, assuming each candidate wins all the states they lead in the Election Graphs five poll averages. This average still includes previous election results since there are no states where there are actually five polls yet.

So what do we see? From the very limited polling we have so far, we see Biden doing noticeably better than any of the other four Democrats when pitted against Trump. In the electoral college, Biden leads Trump by a 42 electoral vote margin. Sanders leads Trump by 6 electoral votes. And then Warren, O'Rourke, and Harris all lose to Trump by 6 electoral votes.

The "tipping point" is perhaps a better way to look at things. It is similar to looking at a popular vote margin, but adjusted for the structure of the electoral college. Here Biden has a 1.2% tipping point margin over Trump and Sanders has a 0.9% tipping point margin over Trump, but Warren, O'Rourke, and Harris all trail Trump by an 0.1% margin.

Frankly, ALL of these results, for all five possible opponents to Trump, are firmly within the "too close to call" zone. Even if it was the day before the election, not 607 days before the election. With this much time left, and with the extremely limited polling so far, any patterns we see may easily disappear as new polls come in. It might even be safe to say they will probably disappear. It is still very very early.

Having said that, the Biden advantage is even more striking as you start looking state by state. The following charts show how the polling average in each state has moved as the polls so far have come in.

Note:Ā Keep in mind these are all measuring how each of the Democrats would fare against Trump in the general election, NOT how they might fare against each other in the primaries.

Watch the red line. The red line is Biden. Down is better for Democrats.

OK, in California Biden hasn't broken out. He hasn't actually been polled in California yet. So his average is just the average of the last five presidential elections.

Biden doing better than the other four Democrats in Texas.

Biden doing better than the other four Democrats in Ohio.

Biden doing better than the other four Democrats in Michigan.

Biden doing better than the other four Democrats in North Carolina.

Biden doing better than the other four Democrats in Arizona.

OK, none of the top five have been polled in Minnesota yet. (Only Klobuchar has been.) So they are all still on one line.

Biden doing better than the other four Democrats in South Carolina.

Biden doing better than the other four Democrats in Iowa.

OK, we finally have a state where Biden has been polled and he isn't doing better than the other Democrats. In New Hampshire, both Sanders and Warren do better against Trump than Biden does.

But that is it. Out of 10 states where we have state polls so far, Biden does better than the other four Democrats in 7. In 2 Biden hasn't been polled yet. Only in 1 does another Democrat do better against Trump.

Now, to be clear, at this stage in a Presidential race, this may be due entirely to name recognition. Most people may still not have much of an idea who Warren, O'Rourke, and Harris even are. But surely they would know who Sanders is, right? His name recognition must be comparable to Biden's. Right?

In any case, the way Biden consistently is outperforming other Democrats against Trump in the polls so far is striking. And he hasn't even officially said he is running yet.

It will be interesting to see if this pattern continues as the field starts to gel, and the other candidates get better known.

Election Graphs will of course update as the new polls come in…
