227 Days Out: Now With Presumptive Nominees

It has been about 66 days since my last post about the general election polls.

That was right before the Republican Iowa Caucus kicked off the delegate chasing season.

Earlier this month both Trump and Biden clinched their nominations.

So now is a good time to start getting back to looking at the general election.

The one sentence TLDR:

  • In order to win, Biden has got to fix his issues in Wisconsin, Pennsylvania, and Michigan, then pull in at least one more place, but there is still plenty of time to do that.

The slightly longer TLDR:

  • Looking at the state by state polls, Trump is still doing very well, and Biden is not.
  • Ignoring the ups and downs in between, overall state by state polls have continued to move toward Trump over the past two months. It is possible Trump is near his ceiling, but there has not been a sustained movement back toward Biden yet.
  • No states crossed the center line over the last two months though, so the electoral college picture still looks pretty similar to how it did last time.
  • Trump is still polling FAR better than he did at the comparable time in either 2016 or 2020.
  • This all comes down to the fact Trump is leading in the poll averages for Wisconsin, Pennsylvania, and Michigan. To win, Biden needs to win all three of these states, plus at least one more electoral vote from somewhere else, or get surprise wins elsewhere to make up for losing one of those.
  • The leads in all three of these states are small enough (under 5%), and the number of undecideds high enough, that this situation could change very quickly as people start paying attention.
  • My "probabilistic views" have Trump at between 96.6% to 99.8% to win depending on how correlated the states are, but it is critical to remember this is conditional on:
    • "Polls don't change at all between now and November" (and we all know they will change a lot), and
    • "The difference between final EG averages and actual election results is similar in 2024 to what we saw from 2008-2020" (which basically means the averages tend to UNDERESTIMATE the Republican by 1.3% percent in the close states, but there are at least some indications polling may be underestimating the Democrat this time).

In other words, and I added a bunch of disclaimers on the site about this, everything here represents a snapshot of NOW. Interpreting the data on this site as a true prediction of November would be a mistake. Things don't become truly predictive until VERY close to the election. There can be large movements in the scale of weeks.

Instead, the right way to think about the information here is as a gauge of how much work candidates have to do, and where they have to do that work.

Right now that translates into "In order to win, Biden has got to fix his issues in Wisconsin, Pennsylvania, and Michigan, then pull in at least one more place."

I do have some ideas but how to model a probability that actually takes into account how the averages may evolve in the time remaining before the election, but I honestly doubt I will have time to execute on that for the 2024 cycle. Maybe for 2028.

OK, now all the specific charts and graphs for those who want to dig in. You should of course also feel free to just explore all the data on the site yourself.

I'm going to restructure how I do these update posts a little bit. As we get closer to the election, I'm going to need to put them out more often, which means I need to make them easier for me to do. Which means more "here is the snapshot from the site" with a little less narrative.

This is the overall summary of all the main stats. Keep in mind all the disclaimers I gave at the top of this post. All three views show Trump heavily favored based on current polling, with a Biden win just barely in the range of possibility. It would be a major upset, and representative of huge polling errors if it looked like this in November and Biden won.

But as I said, and will emphasize once again, we have a long way until the election yet, and things can change quickly.

That's a lot of red. Of course land area doesn't correspond to either population or number of electoral votes. (And Alaska doesn't represent its true area anyway.) But this still gives you an at a glance view. There are only a small number of states with light pastels indicating a really close race at the moment. As usual, the battle will only be in a handful of states.

Looking at the numbers for the subset of the states that are even remotely in contention (margin less than 10%), including how they have changed since last time:

As of January 15th:

As of March 23rd:

Net movement toward Trump:

  • Maine-CD2 (1 EV): Trump by 2.4% -> Trump by 8.6% (Trump+6.2%)
  • Wisconsin (10 EV): Trump by 0.0% -> Trump by 3.0% (Trump+3.0%)
  • Maine-All (2 EV): Biden by 7.8% -> Biden by 5.7% (Trump+2.1%)
  • Pennsylvania (19 EV): Trump by 0.6% -> Trump by 2.6% (Trump+2.0%)
  • Texas (40 EV): Trump by 5.4% -> Trump by 7.3% (Trump+1.9%)
  • Ohio (17 EV): Trump by 9.2% -> Trump by 10.8% (Trump+1.6%)
  • Nevada (6 EV): Trump by 3.8% -> Trump by 5.2% (Trump+1.4%)
  • Colorado (10 EV): Biden by 7.7% -> Biden by 6.6% (Trump+1.1%)
  • Iowa (6 EV): Biden by 10.0% -> Biden by 11.1% (Trump+1.1%)
  • North Carolina (16 EV): Trump by 6.2% -> Trump by 7.2% (Trump+1.0%)
  • Michigan (15 EV): Trump by 4.0% -> Trump by 4.5% (Trump+0.5%)
  • Minnesota (10 EV): Biden by 4.3% -> Biden by 3.9% (Trump+0.4%)
  • New Hampshire (4 EV): Biden by 8.0% -> Biden by 7.6% (Trump+0.4%)

No net movement:

  • New Mexico (5 EV): Biden by 9.3%
  • Nebraska-CD2 (1 EV): Trump by 4.7%
  • Florida (30 EV): Trump by 8.7%

Net movement toward Biden:

  • Virginia (13 EV): Biden by 4.2% -> Biden by 4.5% (Biden+0.3%)
  • Arizona (11 EV): Trump by 5.8% -> Trump by 5.0% (Biden+0.8%)
  • Georgia (16 EV): Trump by 6.7% -> Trump by 5.3% (Biden+1.4%)
  • Alaska (3 EV): Trump by 10.8% -> Trump by 9.4% (Biden+1.4%)

No states crossed the center line at all, so the electoral college picture is very similar to what it was two months ago, but Trump has gotten stronger in states he already was ahead in, and Biden has gotten weaker in states where he was ahead.

There are four exceptions listed above, so there are a few places where Biden has improved, but everywhere else, including the key battleground states, Trump has improved.

Sticking to the categorization view for now, so just taking the poll averages at face value and seeing who leads where, and counting any state where the margin is less than 5% as "in play" we see the chart above.

Basically, the trend from October to December was more and more states moving to a Trump lead margin of more than 5%, putting those states out of reach for Biden as far as this view is concerned, along with a few states where Biden had been ahead by more than 5% dropping to a smaller Biden lead, putting them in reach for Trump.

The range between the Biden best case and the Trump best case narrowed from 250 EV down to 150 EV. Just a lot fewer electoral votes in play, while the "expected" case moved from Biden by 14 to Trump by 88 showing that most of this was movement away from Biden.

Those trends were all about the end of 2023 though.

So far in 2024, there has been limited movement between the categories. A little jittering here and there as various states have crossed category boundaries (often temporarily) but no big lasting directional moves. Most of the changes we looked at earlier on a state by state basis stayed within the broad categories. Thus Trump is stronger when you look at individual states, but the overall electoral college picture hasn't changed too much.

The other way of looking at this, before bringing in the probabilistic models, is what I call the "tipping point". This is the margin in the state that puts the winning candidate over the edge of you order the states by margin. (Or the average of the margins in the two states in the middle if the states are ordered in such a way that there could be a 269-269 tie.)

Basically, this is like looking at a popular vote margin, but adjusted for the structure of the electoral college. In this view you can also see the Biden collapse starting in October, but the time since the new year shows a bit more back and forth, with a bit of improvement for Biden in January, followed by a trend back toward Trump again in February. Then just some jiggling around in March, with no clear trend.

The tipping point shows us that at the moment Biden needs almost a 5% swing to take the lead again in the categorization view. That is a lot, but not out of the question, especially since polls are still showing significantly more than that 5% in all the close states still answering with 3P candidates or "undecided" when asked about the general election.

Now that both candidates have clinched their nominations, the closer we get to November, the smaller that "neither" category should get. Both 3P and "undecided" tend to collapse as elections approach. And how those people end up splitting between, Trump, Biden, sticking with their 3P, or just not voting will probably end up being the deciding factor in the election, more so than Biden or Trump supporters actually changing their minds and flipping to the other side.

These two are the same as the previous two charts, but with the added context of 2016 and 2020.

For Biden supporters, these should be the scariest charts on my site. They show just how much better Trump is doing in polling so far this cycle than he did in either 2016 or 2020.

He was always behind in the polling in both those cycles. He won in 2016. He came close in 2020. The fact that he has been outperforming both of those years consistently, and has been straight up ahead most of the time should be very concerning.

For all the reasons I gave at the beginning of the post, there are lots of reasons to think the situation might be very volatile, and that Trump may be near his ceiling. But the Biden folks would surely feel a lot better if the polling started looking more like 2020, or ideally better than 2020 for them. The fact that they instead look considerably worse than 2016 has to be worrying.

You either have a real situation where Biden is behind and has to make up a lot of ground, or polls are massively underestimating the Democrat this time around, unlike the last two cycles, where they underestimated the Republican.

These views show the range of possibilities for the electoral college margin in the two probabilistic models. These look at the odds in each state, based on assuming the distribution of the difference between the final election graphs average and the actual election results looks similar to the aggregate deltas from 2008 to 2020, then I do automated Monte Carlo simulations to see what the overall general election looks like based on all those state results.

The "Independent States" one assumes no relation in how far off the actuals are from the averages in one state compared to the other. The "Uniform Swing" one assumes that that delta will be the same in every state. Both of these are extremes. The "truth" is somewhere in between.

The darker the band, the more likely a result in that range. You can easily see that right now all the dark colors are in the "Trump wins" part of both graphs, with only lighter colors stretching over to the "Biden wins" part of the graphs.

These two graphs translate the green margin bands into straight up "chance of winning".

I'll say again, because this is very important, this is:

  • Assuming polls look the same on Election Day that they do right now. (Alternately formulated as "if the election was today".)
  • Assuming final poll averages in the close states differ from the actual elections results in a way similar to the aggregate errors in 2008 to 2020. (Alternately formulated as "polls underestimate the Republican again".)

Both of those are big assumptions.

So you shouldn't really read this as "Trump has a 96.6% to 99.8% chance of winning."

Instead read it as "Trump is ahead in all the critical states right now, Biden has a lot of work to do if he is going to catch up and win."

Of course, it might not be Biden doing work, it could also be Trump doing things that hurt himself. You never know. But things have to happen to move things in the Biden direction. If things stay how they are, Trump is heavily favored.

And there we are. That's it for today. Hopefully I don't let it go another 66 days before posting a summary. But I make no promises. I have a lot of things going on and sometimes it is hard to make time to do these posts.

But the site itself is updated pretty promptly whenever new polls come out. Almost always within 24 hours, sometimes a lot less. Right now there are almost always multiple new state level polls every week. By the time we get to September, there will be multiple polls almost every single day. The last three weeks before the election, I'll probably take vacation days off of my day job just to keep up with the deluge of new polls every day. 🙂

So please bookmark and explore the site itself regularly, and also follow ElectionGraphs on Mastodon for daily summaries and posts whenever new polls come out.

227.1 days until polls start to close

Hold on tight.

Delegates: BOTH Trump and Biden Clinch their Nominations

Welp, I expected Trump to clinch tonight, but that Biden would have to wait a week.

But Tuesday morning Green Papers updated their site to note that both Delaware and Florida had canceled their Democratic primaries and given all their delegates to Biden.

That was enough to put Biden close enough to clinch tonight too.

Since my update Sunday for the Republicans and my update Thursday for the Democrats, there have been results in a bunch of states, and some minor adjustments in others. There are still more results pending for tonight. Democrats Abroad, and the Republican caucus in Hawaii.

But I'm not going to wait for them. Here are the net delegate changes since my Sunday post:

  • Biden +484 delegates
  • Trump +137 delegates
  • Haley +3 delegates

And with that, we have presumptive nominees in both parties. The only way this changes is if one or both candidates drop out or become incapacitated or whatever before the conventions.

If that happens, I'll be back with more delegate blog posts. Otherwise, I'll continue to update the delegate totals on the website until the end of the primary season, but won't be posting anything here.

When you effectively have two incumbents, turns out the delegate races are pretty boring. Usually you have at something interesting to follow in at least one of the two parties.

Anyway, here are the important graphs and charts, one last time.

Democrats:

Republicans:

And that's it.

I am way overdue for a general election polling update. I'll get to it as soon as I can.

In the meantime, here are the countdowns until the conventions, one more time:

124.8 days until the Republican National Convention

159.8 days until the Democratic National Convention

 

Democratic Delegates with Hawaii, plus Super Tuesday Cleanup

Welp, first off, Hawaii had a Democratic caucus yesterday.

There may still be some adjustments, but for the moment it looks like 15 more delegates for Biden, and 7 uncommitted that we keep as TBD.

Second, Utah had a Republican caucus on Super Tuesday, but The Green Papers didn't have results until after I did my Super Tuesday summary post.

But we have those results now, and Trump got all 40 delegates from Utah.

So with those updates in, lets look at where everything is right now.

Democrats first:

And now the Republicans:

And that is it for now.

Next up, American Samoa for the Republicans on Friday.

Then a bunch of states on the 12th, and Trump should clinch his nomination.

Biden will have to wait a little longer, until the 19th.

130.1 days until the Republican National Convention

165.1 days until the Democratic National Convention

Delegates after Super Tuesday

Well that was exciting.

Big huge batch of delegates for both parties.

Lets talk Democrats first.

1406 delegates got allocated on the Democratic side, of which 99.8% went to Biden.

There were also 14 more "Uncommitted" delegates in Minnesota, adding to the 2 in Michigan that were already there. But as I mentioned then, these delegates are just free agents who will eventually still vote for someone (probably Biden), so they just count as TBD for us.

But there is that 0.2%. That would be 3 delegates from American Samoa that ended up going to Jason Palmer. Only 91 people voted in the Democratic territorial caucus in American Samoa. But 51 of them voted for Palmer compared to 40 for Biden. So they split the 6 delegates from American Samoa evenly, 3 delegates each.

This is the first person other than Biden to get delegates on the Democratic side this cycle. So we have a race! (Not really.)

Anyway, here are the key charts and graphs for the Democrats. We'll talk Republicans on the other side.

OK, Republicans.

819 delegates were allocated on the Republican side, of which 92.8% were for Trump.

There were also 4 "unbound" delegates in Minnesota. Like the Uncommitted delegates on the Democratic side, these end up essentially as free agents, so are just TBD here. They will probably vote for Trump.

Unlike the Democratic side, these 4 aren't the result of some campaign to have people vote a particular way, but appear to just be a result of Minnesota's particular rules on how to allocate delegates based on the vote results having some delegates "left over", and this is what they do with those.

Fun.

Haley did pick up 7.2% of the delegates from Super Tuesday though, including racking up her second outright win in Vermont, where she got all 17 delegates.

Of course that is nowhere near enough to change the trajectory of the race.

So here are the key charts and graphs:

And that is that for Super Tuesday.

Both Biden and Trump are very close to mathematically wrapping things up, but not quite. We'll have to wait for the 12th on the Republican side and the 19th on the Democratic side for that.

In the mean time, next up is the Democrats in Hawaii Wednesday, and the Republicans in American Samoa on Friday.

131.5 days until the Republican National Convention

166.5 days until the Democratic National Convention

 

Delegates after Michigan Primaries

I meant to post this last night, but I fell asleep. Oops. One delegate changed in the Green Papers estimates since yesterday, so good I waited I guess.

In any case, Michigan had primaries on both the Republican and Democratic sides on Tuesday. For the Democrats, that's it for Michigan. For the Republicans Michigan still has a caucus that allocates most of the delegates on Saturday, so more to come.

On both the Republican and Democratic sides, people are trying to read the primary results for clues to what will happen in November. That's all well and good, but here I'm only going to talk about the delegate race.

On the Democratic side, there was lots of drama in the press about the vote for "Uncommitted", but from a delegate point of view, an uncommitted delegate is just that, a delegate that is still TBD in terms of how they will vote.

As of now it looks like there will be 2 uncommitted delegates coming out of Michigan. But until or unless we get actual people assigned as those delegates, and they declare who they intend to vote for, Biden still has 100% of the allocated delegates.

So yeah. That's what that was about. In terms of delegates anyway.

OK, on the Republican side, Haley got 4 out of the 16 delegates, but of course that was nowhere near what she'd have to be doing to be catching up to Trump. She is just falling further behind, although she is ever so slightly slowing Trump's progress toward the nomination.

Meanwhile, some revisions to the estimates in some earlier states. Haley lost 3 delegates to Trump in South Carolina, and 1 more to him in New Hampshire.

The lower Trump gets, the closer he is to clinching the nomination, the higher Haley goes, the closer she gets to being mathematically eliminated.

No real surprises here.


That is it for today's update. Next up: Republicans in Idaho and Michigan on Saturday, DC on Sunday, and North Dakota on Monday.

Then Super Tuesday for both parties.

137.8 days until the Republican National Convention

172.8 days until the Democratic National Convention

Democratic Delegates after South Carolina

Well, this is boring.

Biden gets all the delegates from South Carolina.

This was also completely expected of course. The only place where the token opposition of Phillips and Williamson were expected to be able to get a non-trivial amount of support was in New Hampshire, where Phillips got 19.66% of the final vote, and Williamson got 4.05%, just ahead of write-in votes for Republican Nikki Haley at 3.84%. But of course no delegates were awarded based on that vote. New Hampshire will undoubtedly eventually get to send delegates to the convention, but how they will be allocated is yet to be seen.

Here in South Carolina, as of a few hours after poll closing, the partial count has Biden with 96.22%, Williamson with 2.08%, and Phillips with 1.71%. To get any delegates, Phillips or Williamson would have had to do MUCH better than that, either state wide, or at least in one of South Carolina's 7 congressional districts. Either way, they were not even close.

So Biden gets all 55 delegates from South Carolina, and starts on what will likely be an uninterrupted journey toward clinching the nomination on March 19th, the first date where it will be mathematically possible.

We'll track the updates as they happen from now until then, but unless something very unexpected happens, there won't be any drama.

Here is the main "% of remaining delegates needed to win" chart:

And the tabular summary of where things are:

Next up, Democrats in Nevada on Tuesday night.

It will probably be just as boring. But we will be here to confirm!

162.8 days until the Republican National Convention.

197.8 days until the Democratic National Convention.

Election Day: Final Tightening?

It is Election Day.

Election Graphs has logged its last poll on Twitter for the 2020 season. In just a couple of hours, polls will start closing, and we will start getting actual election results.

So where did Election Graphs end up? What is our final prediction?

If you just want the bottom line, without any of the pretty charts or discussion, it is this:

Biden continues to be heavily favored to win. He is still in a stronger position than Clinton was four years ago. However, our numbers show a significant last-minute strengthening by Trump which makes Biden's lead much more tenuous than it was a week ago. If we had the same size polling error as 2016 in Trump's direction, he would win. (The same size error in the other direction would get to a Biden landslide… there are LOTS of close states.)

Having said that, the nature of some of the recent polls raises a real question about how much of this final move is "real" rather than just a lot of partisan and lesser-known pollsters flooding the final averages with polls that are favorable to Trump.

OK. If that is all you need, goodbye! See you for the 2024 cycle!

If you want more detail though, keep reading.

(There will also be a post tracking results as they come in tonight, and eventually, later this year once all the results are known and final, an analysis of how we did, so if those interest you, check back in later!)

The last blog update here was yesterday on November 2nd. There were hundreds of new polls (or at least it seemed that way) on that last day. Here are the changes in our metrics just in the last 24 hours.

On the one hand, North Carolina moved back to the Biden side of the centerline. Which strengthens Biden by 30 EV in both the Uniform Swing Median and the Expected Case Median. But in the meantime, the huge wave of final polls reduced Biden's margin in the critical "Weak Biden" states.

And yes, it is the same thing I mentioned last time when I said:

There have been dozens of new polls since the update on the 31st. While there were exceptions, the overwhelming theme was polls showing a better picture for Trump and a worse one for Biden than we had seen any time recently. So almost all of the metrics above move in Trump's direction.

As with a couple of the other recent spikes toward Trump in the last few weeks, you can look at the specific polls in the average, and start wondering if this is just a bunch of right-leaning pollsters flooding the zone with polls in the last few days. While there were plenty of results from large mainstream pollsters released in these last few days, there were quite a few partisan polls released too, and some of them definitely helped move the averages toward Trump. I talked about this phenomenon on October 20th, October 24th, and October 31st… so I won't delve into that in-depth again.

…

Will this deteriorate further in the limited time left? Or bounce back? Or neither? If I had to guess, I'd say reversion to the mean. There have been no major news events in the last week that would seem likely to drive a tightening. So I expect this "tightening" is actually just an artifact. But that is just an educated guess. We will all know soon enough.

It did not revert to the mean. Biden's situation deteriorated a lot more. It ended up being significant in the final numbers.

So I guess I do have to delve into it again. Bottom line, in the last few days before Election Day, every pollster in existence seems to have wanted to make sure they got a shot at Election 2020, and a huge volume of polls was released. Many of these were from pollsters that have clear partisan leanings, and whose results were much more positive to Trump than what we had been seeing. Others were just lesser-known pollsters.

Election Graphs uses a "Last X Polls" model, specifically so that as the election approaches and there is more polling, we look at shorter and shorter timeframes and are more responsive to changes. We also use the mid-date of polls to determine just which polls are part of the "Last X" rather than the end-date. This means that in terms of the "final" averages we favor the very last-minute polls put out with very short times in the field.

The result is that many of the large well-known polling companies with good reputations that put out their final polls late last week or even over the weekend got crowded out of the critical state averages by the large volume of random polls, which often just covered one or two days in the field.

Those pollsters tended to be much more bullish on Trump than the usual suspects who had been polling this race regularly over the last year.

So the averages in many states jerked a few percentage points toward Trump, just in the last few days.

If there was a big event in the news that was bad for Biden, then it would be easy to say that was the cause. The closest thing to that has been the drip-drip of information about Biden's son, but for the most part that has not seemed to actually get much traction. But maybe?

In the absence of a clear reason for movement, while there is most definitely a clear difference in the nature of the polling that comprises the average, it seems reasonable to think that maybe the movement is just an artifact of the polling, and doesn't represent a real change.

So perhaps the picture the site had of the race a week or two ago is actually a better representation of what is happening?

Maybe.

But four years ago we had a similar move in the last few days before the election. And that time it also seemed to be driven by a surge of polls from outlets that hadn't been doing a lot of polling earlier in the cycle. And we ended up closer to the final result because we reflected the change caused by those polls. That last burst of polls ended up being closer to reality than the more established pollsters they displaced.

Of course, that could well have just been luck too.

We set the rules for how we define the averages, what we would include and would not include, etc over two years ago, based heavily on what we did in 2008, 2012, and 2016. We're not going to change anything on the last day.

So it is what it is.

We'll find out in a few hours if the short time frames and the burst of lower quality polls ended up causing Election Graphs to dramatically overestimate Trump and underestimate Biden. If we are way off, maybe we'll change something for 2024. Or maybe the movement seen in these last 48 hours actually better represents what is going on.

I don't know. We will see.

So I can give the caveats above, but the numbers are what they are, and so we'll do the rest of this discussion taking them at face value.

Let's look at all the graphs.

First of all, the comparison with 2016:

After a brief spike toward a stronger position for Biden, the collapse we have been talking about happened. The final tipping point was only a 2.3% Biden lead. Biden had seen worse tipping points, but not since early June.

Even at this level though, Biden is stronger than the 1.6% that Clinton ended with. So he is still in a better position.

However, the difference between the Election Graphs final tipping point and the actual election results in 2016 was 2.36%. So the same size error in the correct direction would make Trump the winner.

In terms of the expected case, where each candidate wins every state where they lead the Election Graphs average, Biden is in the low end of his recent range, but not any lower, and still significantly ahead of where Clinton was.

OK. Let's look at the range of margins predicted by our three models:

In all three of these cases, the center lines have moved toward Trump, but are either still in their normal ranges, or are just barely out it. What has changed though is that in all cases the upper end of the envelopes, representing Trump's best cases has stretched out significantly further into the Trump wins zone.

This makes sense because most of what we saw was not states actually flipping from Biden to Trump in the averages, just Biden's lead in states being significantly diminished. So the straight-up scenario that happens if the averages are all correct doesn't move much. But the sensitivity to the averages being wrong and therefore states flipping to Trump based on those errors increases significantly.

As a sanity check, let's compare our three centerlines with what other sites are saying at the moment:

So I'm in the zone. Most of the big folks have Biden doing better than I do, but there are a few places that have him doing worse.

And the Election Graphs "expected case" exactly matches what the Upshot says would be the result if the polling error in 2020 was the same magnitude and direction as the error in 2016. Which is interesting.

I note of course that nobody has Trump winning in their "expected case".

OK, with that done, let's look at odds.

While still small, the red zone in the Independent States odds view is now significantly larger, with Trump's chances now at 2.5%.

Trump's odds in the uniform swing model are massive now though, at 31.9%.

Fundamentally, since this imagines the extreme case where all the states move in a completely synchronous way, the only thing that matters is the odds in the tipping point state. And as of the final situation, the tipping point is Pennsylvania, and our average has Biden leading Pennsylvania by only 2.3%.

And in our analysis of our results from 2008 to 2016, we discovered that when we have a Democrat leading by 2.3%, that translates into a 68.1% chance of the Democrat winning, and a 31.9% chance of the Republican winning.

So Trump's chance of winning Pennsylvania is 31.9%, and if all the states are locked together, that means his odds of winning the whole election would be 31.9% too.

Since both of these models are extremes, and the truth is somewhere in between, the official Election Graphs statement on Trump's chances at this point is "between 2.5% and 31.9%". Election Graphs doesn't actually model where the right spot is within this range, but the middle is as good a spot to look at as any. That would be a 17.2% chance of a Trump win at the moment.

Once again, let's compare with the other folks:

My two extreme models are unsurprisingly near the extremes. "The middle" puts me lower than most of the "big" outlets. So maybe they think which there is some correlation between the states, their models still think they are more independent than not.

In any case, Biden is a favorite in all of these views. But in some, the chances of an upset are much more than others.

Not including the three from me, the median is a 9.3% chance of a Trump win. Including all three of mine, the median is 10.0%.

So as usual I make the statement that people tend to be bad at interpreting odds. 10% is not 0%. 10% happens all the time. Biden is favored, but a Trump win is still very possible.

Looking at the tipping point without the 2016 comparison, the main thing to notice is the huge volatility at the end. Swinging first in favor of Biden, then against him. This is an indication that perhaps for 2024, I should look into ways to make this a little LESS sensitive to short term changes in the last weeks.

OK. Time for the map and spectrum:

This view makes the volatility of the race clear. There are 10 states (and Maine CD2) with margins less than 5%.

The polling error in 2016 was 2.36%. There are 8 states closer to the centerline than that, including the tipping-point state.

If we get a 2016 size error favoring Trump, we get a very narrow win for Trump, squeaking past the post with an 18 EV margin.

If we get a 2016 size error favoring Biden, Biden wins by 288 EV, the largest winning margin since 1988.

More likely than either extreme of course is that we just get a solid but not extraordinary Biden win.

And now the trends in all the close states:


And that is that.

It is election night. The first results will be coming out within a couple of hours. We may or may not end up knowing who wins tonight, but we'll still learn a lot. And soon enough, we will indeed have a winner.

I hope you have enjoyed Election Graphs and found it useful this year. Aside from seeing how things turn out and how we did, we are done.

It was fun. Thanks everyone!

3.5 Days Out: No Big Changes

As always, if you are impatient for one of these updates, the 2020 Electoral College pages on Election Graphs are updated multiple times every day as new polls come in. Or you can follow @ElecCollPolls on Twitter to see all the polls as I add them. While you are at it, follow @ElectionGraphs too.

The last blog update here was early UTC on October 28th (with numbers as of the end of the 27th UTC). Just over three days ago. Here are the high-level changes since that last post:

I'm updating more often since we are so close to the end, but the bottom line is again that things are fairly steady. If you look at the numbers above, yes, they move around a bit. But we still have nothing that looks like a sustained move as opposed to just poll averages meandering up and down as specific polls come in and out of the average.

Now, if I'd been making this post a bit sooner, it might have looked a lot like my "The Race Tightens? Or Not?" post from October 20th. This time the tipping point moved from Biden+4.4% on the 27th, down to Biden+3.1% on the 29th. I would be asking if this was the beginning of the race starting to tighten.

But as with that post, I would have expressed skepticism because just as it was back on October 20th, this spike was driven by a rash of polls from pollsters that tend to put out outliers. As new polls came out on the 30th, the tipping point bounced back to Biden+4.3%, almost back to where it had been before. It was just a transient spike.

In some cases the outliers that drive this are extreme. In one dramatic instance, Trafalgar came out with a poll showing Trump ahead by 2% in Michigan at a time when the other polls in the Election Graphs average ranged from Biden+7.7% to Biden+13%. The Trafalgar number was not just at the Trump end of the range we had been seeing, it was on a whole different planet.

Whenever I see polls like that come in, I start wondering if I shouldn't have switched Election Graphs from using averages to using medians years ago. Or maybe that I need some sort of weighting by historical pollster accuracy, or to do something more complex to deal with and adjust for outliers, or just include more polls to wash these outliers out a bit more.

But one of the main ideas of Election Graphs from the beginning has been to include everything and keep to relatively simple averages, and see how far that gets you. It does make us bounce around when we get outliers though, and makes us VERY sensitive to just which pollsters have been in the field most recently.

If there is a REAL move, then after you get a spike led by a particular poll, additional polls will confirm the move, and you'll see a sustained change that lasts even after that first poll rolls off of the average. When it is just a movement driven by an outlier though, things will move back to where they were once a few new polls come in.

The problem here at the very end of the race is that at some point there will be no new polls. The last pollsters in the field will dominate the average. And they may or may not be the ones with the most accurate results. Last time around in 2016 Election Graphs did pretty well. Maybe we were lucky. We'll see how it goes this time.

For the moment though, when you look at the graphs, it seems that after a brief spike where it looked closer for a moment, we're back in the same familiar territory for this race as we have been since June, showing Biden as a heavy favorite, but with the possibility of a Trump upset not completely out of the picture.

So let's look at all the graphs.

First 2020 vs 2016 comparisons since everybody on both sides keeps saying "But what about 2016?" when people talk about Biden's lead.

In the tipping point, which represents the degree polls need to be wrong and/or change before the end in order to flip the winner, Biden now holds a 4.3% lead. Clinton was at 1.6% by this point in 2016.

Biden is closer to the 4% part of his "normal range" than the 6% end, but we are still in very familiar territory. This race is pretty much in the same place it has been for months, Biden remains stronger than Clinton was, and we do not see any evidence of a collapse.

In terms of the expected case, where each candidate wins every state where they lead the Election Graphs average, Biden is still pretty much in the center of his normal zone, and significantly ahead of where Clinton was.

OK. Time for the three envelopes we have covering this year:

Instead of saying it three times, I'll say this once, since it is the same for all three:

There has been no substantive change to the race in months. All of these charts just show little bounces up and down as polls move in and out of the averages.

Fundamentally, the race looks the same now as it did at the beginning of August or even mid-June.

In terms of odds from the probabilistic views, the Independent states chart still looks like a big blue square. Biden's chances in that model have been pegged near 100% for many months.

So looking at Uniform Swing…

In this view, Trump is now at a 14.6% chance of winning. That is higher than his chances have usually been, but not out of the range we have seen.

Since both of these models are extremes, the official Election Graphs statement on Trump's chances at this point is "between 0.1% and 14.6%".

We don't officially specify a spot within that range since we haven't modeled how much correlation between states to expect, but I guess the midpoint is as good a value to look at as any other. The middle of that range is 7.4%.  That intuitively feels reasonable. Not total correlation, not total independence, but right in between. And frankly, that seems to be in the same general ballpark as all the big players who are doing election modeling. So call it 7.4%.

At 7.4%, Trump has about a 1 in 14 chance of winning. That would clearly be an upset, but is not so far out of the realm of possibility that people should be thinking about it as if a Biden win was a done deal. Of course, because of 2016, almost nobody is.

By contrast, Trump was at about 14% in 2016 if you looked at the median of all the sites giving odds. That would be about a 1 in 7 chance of winning.

So yes, Biden's polling lead is not so great you can say that there is a negligible chance of a Trump upset, but the chances of that kind of an upset are around half what they were in 2016.

This is just zooming in on the Tipping Point line without the 2016 comparison. Like all the other charts, this shows some bouncing around, but fundamentally a static race. The few times it looked like we might have been breaking into new territory in one direction or the other, it has proven to only be a short term spike once more data came in.

Of course, there is no guarantee that something won't change in the last few days, but there simply isn't much time left for a significant change.

Looking at this spectrum, one thing that you can look at more clearly than some of the other views is imagining polling errors of the sizes we have seen in the last three elections.

As measured by the difference between the final Election Graphs tipping point, and the actual tipping point based on votes cast in the elections, you had these errors:

  • 2008: 3.45%
  • 2012: 0.89%
  • 2016: 2.36%

Assuming uniform swing, and that the polls are overestimating Biden:

  • 2012 level error: Just our expected case, Biden wins by 176 EV
  • 2016 level error: Trump wins the states he leads, plus Maine CD2, Iowa, Arizona, and North Carolina. Biden still wins, but only by 110 EV.
  • 2008 level error: Trump wins all the states above, plus Georgia and Florida. Biden still wins, but only by 20 EV, and with only an 0.85% margin in the tipping point state of Pennsylvania… perhaps within range of complicating things with recounts and court challenges.

So in order to win based on "polls were wrong" (rather than a last-minute move in the polls in the next few days), we would need a bigger polling error than we have seen in the last three cycles.

On the other hand, also assuming uniform swing, but this time assuming the polls are overestimating Trump:

  • 2012 level error: Just our expected case, Biden wins by 176 EV
  • 2016 level error: Biden wins all the states he leads, but also Ohio and Texas, which ends up at what we call Biden's best case, winning by 288 EV.
  • 2008 level error: Biden by 288 EV. Same result as the 2016 level error. Even a 2008 level error isn't enough to pull in wins for Biden in the next closest states of Montana, Alaska, and Missouri.

And now the trends in all the close states:

That is all for today.

3.5 days until the first results start coming in on election night.

We are so close. Almost there now.

So, as we are only 7 days out now, I'm trying to update much more frequently. But honestly, not much has changed since the post three days ago.

Some states have bounced around. Biden had taken a tiny lead in Texas last time. Texas has now moved back to a small Trump lead. Meanwhile, Georgia had bumped into a small Trump lead but is now back to a small Biden lead. Iowa crossed the center line too, moving from Trump to Biden. Florida moved from Weak Biden to Weak Trump, and then back to Weak Biden again since last time as well.

All of these are states that are really toss-ups getting jostled around by whatever individual polls come out at any given moment. There is still no evidence of any sustained trend.

It looks like we are back once again to the part of the normal range that is most favorable to Trump, but we are still in the same range we have been since June. That translates to the reasonable possibilities ranging from a narrow Trump win if there is a substantial polling error or last-minute move, to a Biden landslide if the error or move goes in the other direction.

That entire range is reasonably possible, but the most likely outcome continues to look like a Biden win of a magnitude somewhere between Obama's 2012 win and Obama's 2008 win.

So with that out of the way, let's just look at all of the graphs.

This time, we'll start with 2020 vs 2016 comparisons since that continues to come up again and again in the discussions of this election cycle.

In the tipping point, which represents the degree polls need to be wrong and/or change before the end in order to flip the winner, Biden now holds a 4.4% lead. Clinton had dropped to 1.3% by this point in 2016.

Biden is closer to the 4% end of his 4% to 6% range than he is to the 6% end, but he is still in the same zone he has been in for a long time. By this time Clinton had collapsed and there was a really close race happening.

To be fair though, 7 days out from the 2016 election we didn't know this yet. Her tipping point number at the 7-day mark as we look back at it today is influenced by polling that was in the field at this point, but not actually released until the last few days before the election. The first Election Graphs post noting the final Trump surge in 2016 came at the 4-day mark.

So while we haven't seen any signs of Biden collapse yet, and Biden's pattern has been much less volatile than Clinton, this is just another reminder that Clinton's final collapse didn't show up here until the very very end.

In terms of the expected case, where each candidate wins every state where they lead the Election Graphs average, Biden is pretty much in the center of the normal zone. Within the last two weeks, the expected case has ranged from Biden +86 to Biden+240. That is a huge range!

But with Texas (38 EV), Florida (29 EV), Georgia (16 EV), and Iowa (6 EV) all close enough that they are flipping back and forth across the center line semi-regularly, having volatility of this sort should be expected. With the exception of one brief moment though, Biden has consistently been ahead of where Clinton was four years ago, and usually by quite a bit.

OK. Forget 2016 now.

Time for the three envelopes we have covering this year:

Our median of the probabilistic view assuming all states are completely independent shows us near the top end of the normal range, but still in the range.

The 3σ envelope (99.73% of all outcomes within the bubble) just barely stretches to a Trump win by 4 EV, while the other end of this bubble would be Biden winning by the largest margin since Bush beat Dukakis in 1988.

The darker bubbles are of course more likely than those extreme scenarios. The 1σ (68.27%) range goes from Biden by 84 to Biden by 206. Comparing that to previous elections, that is basically from a narrow win similar in scale to Trump's win in 2016 to a Clinton 1992 level win on the other.

Converting this to odds, this view has Biden with a 99.8% chance of winning. This is down a little from before, but still so close to 100% that our chart of this just looks like a blue box. So we once again skip that chart.

As we have discussed before though, the independent states view results in the narrowest possible distribution of possibilities, since a candidate outperforming the polls in one state tends to be balanced by underperforming in another.

The uniform swing view instead locks all the states so they move together. This results in a much wider range of possibilities, since now if a candidate overperforms the polls, we assume they do so in EVERY state.

With this view, the 3σ (99.73%) range goes all the way from Trump beating his 2016 numbers with a 114 EV win, to Biden having a landslide even bigger than Bush in 1988 (but not quite as big as Reagan in 1984).

This view also shows a race with very little movement though.

Looking at the odds corresponding to the uniform swing view, Trump is now at an 11.8% chance of winning. Again, not breaking new ground.

Both of these views are extremes though. The official Election Graphs view of Trump's chances at this point is "between 0.1% and 11.8%". The middle of that range is just about 6%, but we don't specify a spot within the range since we haven't modeled how much correlation between states to expect.

And of course the good old categorization view we have used on Election Graphs since 2008. The lack of movement in this race is even more obvious in this view.

Biden's best case (where he wins every single state with a margin under 5%) barely moves at all.

Trump's best case does wander a little bit as some blue states dip over and under the 5% Biden lead line, but there is no trend here. At the moment though, if Trump wins every one of the close states, he squeaks out a 20 EV win.

Similarly, the centerline just meanders up and down as the very close states move back and forth between "Weak Biden" and "Weak Trump" as new polls bat them back and forth.

But overall, we just don't have any substantial change in the overall picture or trend in months.

Without the 2016 comparison line, we're more zoomed in on the tipping point here, so it looks like this is swinging dramatically, but that is just the scale. Aside from very brief moments, this has been between 4% and 6% for months.

OK, now the map and spectrum of the states:


And now the trends in all the close states:

And that is that.

7.0 days until the first results start coming in on election night.

One week. That's all.

Last time we talked a lot about how the big move in Trump's direction we saw then could very well just be a transient thing because there was a rush of Pennsylvania polls from small pollsters that were favorable to Trump, which might not be sustained once the bigger pollsters released new results for Pennsylvania.

That is exactly what happened. In the days since that blog post, there were quite a few additional polls released in Pennsylvania. Here is what Pennsylvania looks like now:

A brief foray into "Weak Biden", and then right back to "Strong Biden".

These results not only moved the tipping point back toward Biden, but they also knocked the top off the peak we saw last time, so instead of the tipping point getting down to a 3.1% Biden lead, now Biden's worst tipping point was only 3.6%.

The tipping point is now at Biden by 4.9%, right smack in the middle of that 4% to 6% range it has normally been in ever since mid-June.

Not only that, but the same is true of almost all of the main metrics. They are all in their "normal ranges".

Let's take a quick look:

The Tipping Point, the Independent States View, the Uniform Swing View, the Categorization View, and the odds generated from the two probabilistic views all show the race back in the "normal zone". (I didn't bother with showing the second odds chart since it is just a blue rectangle.)

So bottom line, a few days of bad polls in Pennsylvania moved things in Trump's direction. But with more polling, it doesn't seem like a "real" move representing a fundamental change.

Instead, it once again looks like this race has basically been frozen since June. The moves up and down we see are mostly just random results of which pollsters released results recently, and normal sampling errors and such. Very little, if any, real movement.

Roughly speaking, ever since June, this has looked like a race where Biden leads by between 4% and 6% in the tipping-point state, with a potential winning margin somewhere between 100 and 200 electoral votes.

We still have 11 days left of course. There is still a little bit of time left for that to change.

And also, there is still the possibility of a systematic polling error. Between our two probabilistic models based on how far off Election Graphs state averages were in 2008, 2012, and 2016, the Election Graphs estimate for Trump's odds of winning if the election was today currently stand at "somewhere between 0.1% and 9.1%".

Where in that range depends on how closely linked the results in the different states are, which we don't estimate. But everyone needs to continue to remember that 10%, or 5%, or even 1% aren't the same as 0%, and there are still paths to a win for Trump. This isn't over yet.

The map and the center of the spectrum of states look like this now:

To win, Trump needs to run the table and win every single close state, or pull in some not so close states.

Let's do the comparison to 2016 now:

In terms of the Electoral College in the categorization view, Biden has been in a better spot than Clinton since we hit 76 days out, most of the time being more than just a little bit ahead of her pace.

But Biden's tipping point has been comparable to where Clinton's was at the same point four years ago for the last few weeks. Biden has not been consistently ahead of Clinton on this metric.

As of this blog post, Biden is once again ahead of where Clinton was though. Eleven days out Biden is at 4.9%, Clinton was at 3.2%. And it was mostly downhill for Clinton after this point.

Clinton's final drop was precipitated by the Comey letter. So far nothing comparable has hit Biden, and as I write this, nearly 53 million votes have already been cast. So yes, something could still change, but time is running out fast.

OK. We didn't do it earlier in the post, so here is a quick look at the current graphs for all of the states and CDs where the Election Graphs margin is currently under 5%. I won't comment on all of them individually. Some of them have switched categories in the last few days, some have not. But all of these should be considered as active possibilities for both candidates at this point.

And that is it for today. More soon.

10.9 days until the first results start coming in on election night.

We are almost at the end!
