More Weakening for Democrats

Since the last blog post on December 22nd, there have been two new state-level polls released: one Mason-Dixon poll in Florida and one Mason-Dixon poll in Virginia. Each of these pitted Sanders, Biden, Warren, and Buttigieg against Trump.

From the categorization view, we had the following changes:

Warren vs Trump:

  • State category change: FL has moved from Weak Warren to Weak Trump
  • State category change: VA has moved from Strong Warren to Weak Warren
  • Expected case change: Warren 276 to Trump 262 -> Warren 247 to Trump 291
  • Trump best case vs. Warren has changed: Warren 213 to Trump 325 -> Warren 200 to Trump 338
  • Tipping point change: Warren by 0.6% in FL -> Trump by 0.5% in NC

With this, the "envelope" for Warren vs Trump looks like this:

This shows the full swing between all the states with margins under 5% going one way, and all of them going the other way. With Florida flipping back to a 2.0% Trump lead, Warren once again loses the Electoral College if every state is won by the current poll average leader.

The tipping point moves similarly:

Both of these views show Warren struggling over the past few months to stay ahead of Trump.

When we determine who is winning the Electoral College simply by seeing who leads the poll averages in each state, Warren has sometimes been ahead but has also been behind. The tipping point has been less than 1% for almost a year… since we started getting polls really… so one way or another, Warren vs Trump looks like a close race.

Buttigieg vs Trump:

  • State category change: VA has moved from Weak Trump to Weak Buttigieg
  • Expected case change: Buttigieg 226 to Trump 312 -> Buttigieg 239 to Trump 299
  • Tipping point change: Trump by 1.3% in MI -> Trump by 1.8% in FL

There has been much less polling on Buttigieg vs Trump. This last polling actually moves Virginia in Buttigieg's direction, but that is only because this is the very first Buttigieg poll in Virginia, so it bumps the 8.0% Republican win in 2000 out of the average. The newest poll still had Trump ahead by 2.0%, but because it was less of lead than Bush's win in 2000, it moved the average toward Buttigieg,

But the Florida poll moved the average in that state the other way and the tipping point moves further toward Trump.

None of the categorization based metrics changed for the other candidates, but let's look where things stand right now with everybody before we move on to the probabilistic view.

Dem 22 Dec 6 Jan 𝚫
Biden +178 +178 Flat
Sanders +58 +58 Flat
Warren +14 -44 -58
Buttigieg -86 -60 +26

So in the Expected Case, Biden still way ahead, Sanders ahead but not by as much, and we now have both Warren and Buttigieg losing.

Dem 22 Dec 6 Jan 𝚫
Biden +4.3% +4.3% Flat
Sanders +1.0% +1.0% Flat
Warren +0.6% -0.5% -1.1%
Buttigieg -1.3% -1.8% -0.5%

In the tipping point view, you can see a bit more clearly how much better Biden is doing than the rest.

However, to be clear, this is still not a secure lead. One month before the 2016 election, Clinton had a 6.0% tipping point lead. Over the course of the last month, this kept slipping, and the actual tipping point in the final election results was Trump by 0.8%. So with the right set of events, the tipping point can move 7% in a month.

We have a long way to go.

Having said that, the categorization view does simplify things. While the poll averages for Biden and Sanders did not change categories, they did move. So let's look at the state averages, and then the probabilistic views:

Biden is now the only Democrat who still has a lead in the Florida poll average. But the bottom line is that whatever Democrat you look at, Florida is close. The range for the four Democrats still in the race goes from a 1.4% lead for Biden to a 2.0% deficit for Warren. Florida is simply too close to call no matter how you slice it.

Once again, in Virginia Biden is doing much better than the other Democrats against Trump. In Virginia Biden is ahead by 9.6%. The other three Democrats who are still in the race all lead, but none by more than 4%.

OK, now for the results of the national probabilistic simulations:

Dem 22 Dec 6 Jan 𝚫
Biden +126 +132 +6
Sanders +54 +46 -8
Warren +22 +2 -20
Buttigieg -44 -48 -4

The median case only improves for Biden. For every other Democrat, the situation deteriorates, with Warren taking the biggest hit.

One thing to point out is that while Warren loses by 44 electoral votes in the categorization view, looking at the probabilistic simulation, the median case has Warren eking out a 2 electoral vote win.

Why the difference? Because Warren's spectrum of states looks like this:

If everybody wins the states they lead, Warren loses by 44. So she needs to flip 22 electoral votes for a 269-269 tie, and any more than that gets her a win.

There are 121 electoral votes worth of states where Trump leads by 3% or less. Meanwhile, there are only 24 electoral votes worth of states where Warren leads by less than 3%.

To pull off a win, Warren needs to hold Pennsylvania and New Hampshire, but then out of the eight states where Trump has a narrow lead, she only has to get lucky in Florida, or any number of combinations of two states, in order to pull things back over to her side. Given how many states are very close, and how few are close on the other side, it is actually still pretty likely that one of those things would happen.

So how likely?

Dem 22 Dec 6 Jan 𝚫
Biden 99.4% 99.5% +0.1%
Sanders 82.6% 78.0% -4.6%
Warren 66.1% 50.8% -15.3%
Buttigieg 16.5% 14.4% -2.1%

Warren's odds of winning with that distribution of states is 50.8%. Warren vs. Trump is sitting about as close to a coin toss as we could expect to see.

The odds of a 269-269 tie are also at 1.7%, which is higher than for any of the other three active Democrats here.

Looking at the others, Biden remains at 99%+ with Sanders a bit behind that around 80%, and Buttigieg very very far behind, with only about a 14% chance of pulling out a win.

Of course, that is about the same odds folks gave Trump in 2016.

So that is where we are.

Looking at Virginia

I'm trying to get back in the habit of more frequent updates in preparation for actually entering 2020, but there is not much new this time.

Since the last update on December 16th, there has only been a single poll in Virginia. And they only polled Sanders, Biden, and Warren vs. Trump.

The categorization style changes resulting from this were:

  • Biden vs. Trump state category change: VA has moved from Solid Biden to Strong Biden
  • Sanders vs. Trump state category change: VA has moved from Strong Sanders to Weak Sanders
  • Trump best case vs. Sanders has changed: Sanders 217 to Trump 321 -> Sanders 204 to Trump 334

Since there is relatively little new polling this time, instead of just looking at some of the overview candidate comparisons, let's look at each of the Virginia results.

Pollsters have not paid enough attention to Virginia. For Sanders, there have only been three polls. One from UMW and two from VCU. Each of these has released multiple "views" of their data. These detailed results are why you see more than three dots on the chart. For instance, in the latest, a new VCU poll gave results for "all," "registered voters," and "likely voters."

For Sanders vs. Trump, those broke like this:

  • All: Sanders 46% to Trump 46% (Tie)
  • Registered Voters: Sanders 45% to Trump 47% (Trump +2%)
  • Likely Voters: Sanders 45% to Trump 48% (Trump +3%)

When a single poll releases multiple results, Election Graphs essentially averages the results. So, in this case, these three results together count as a Trump +1.67% poll.

The Election Graphs average now contains three actual 2020 polls, plus the 2016 and 2012 election results to round out the average giving Sanders a 4.4% lead in Virginia.

Just looking at the three actual polls, though, you can see each subsequent result has been worse for Sanders than the previous one. That is probably not the trend he would like to see.

But this is where I go back to what I said at the start. There have only been three polls. It is easy to see trends that are not real when you only have three data points. We need more.

But this last poll moves the average back into the competitive zone. Although Virginia has been trending blue, Democrats may not want to take it for granted.

Biden vs. Trump also shows each of the last three polls weaker for Biden than the one before. Except there is one additional 2020 poll, the leaked Trump internal poll from March. That provides one more data point showing a strong Democratic lead, and Biden's numbers have been better than Sanders anyway, so we end up at a Biden +9.9% average, which is slightly worse than the 10.1% lead before this latest poll. The line isn't moving toward Trump as much as with Sanders, but Biden still shows weakening.

The latest couple of polls have been significantly weaker, though, so again, we need more Virginia polls.

Warren shows a similar pattern to Sanders, except a little bit stronger, with the average standing at a Warren +5.0% lead.

The Democrats weakening in Virginia continues the trends I discussed last time. The fall was not great for the Democrats.

The longer-term trends are evident in the graphs, but see the charts below for the new changes caused by the one new VCU poll in this update.

Dem 16 Dec 22 Dec 𝚫
Biden 99.4% 99.4% Flat
Sanders 83.5% 82.6% -0.9%
Warren 67.2% 66.1% -1.1%
Buttigieg 16.5% 16.5% Flat

Dem 16 Dec 22 Dec 𝚫
Biden +126 +126 Flat
Sanders +56 +54 -2
Warren +24 +22 -2
Buttigieg -44 -44 Flat

On the categorization view, there were no changes to the Expected Case or Tipping Point numbers, so we'll skip those this time.

And that's where we are.

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 page 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 𝚫
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 𝚫
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. This 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.

Blue Virginia

Since last week's update, there was only one new poll released, a University of Mary Washington poll of Virginia.

They polled Biden, Sanders, Warren, and Harris against Trump. No new data for Buttigieg or O'Rourke.

This poll was the first public polling of Virginia this cycle. The only glimpse we had previously was leaked Trump internal polling from March which only included Biden.

Virginia has been trending blue over the last few elections, but Election Graphs starts with the average of the previous five elections before we have polls and the average margin from 2000 to 2016 ended up as a 0.1% Republican lead.

The leaked Biden vs. Trump poll moved the state from Weak Trump (by 0.1%) to Weak Biden (by 4.9%) in the Election Graphs average, but with no 2020 data, all the other Democrats remained in "Weak Trump" territory despite the general sense that because of the trends in Virginia, this was unlikely to stay the case.

At long last, we have a new public poll of Virginia though. So we start to see how the state looks for 2020.

All four Democratic candidates led Trump by double digits in this new poll. The poll averages still include some older election results though, since this is the first 2020 polling in Virginia for every matchup except Biden vs. Trump.

In terms of categories, this moved the state from "Weak Trump" to "Weak Democratic" for Sanders, Warren, and Harris.

Biden, having already taken the lead after that leaked Trump internal poll, now moves from "Weak Biden" to "Strong Biden."


In terms of odds of winning, that means that every Democrat that has been polled in Virginia so far is estimated to have an 80%+ chance of winning the state according to the historical accuracy of Election Graphs poll averages.

As usual, I must repeat the universal caveat on this site: These numbers are if the election was today. The election is not today, a lot will change between now and then.

Also, in this case, we still have sparse polling.

So, what does the national picture look like now in terms of the chance of the Democrat winning?

Dem 22 Sep 29 Sep 𝚫
Biden 99.9% 99.9% Flat
Sanders 95.3% 97.2% +1.9%
O'Rourke 83.1% 83.1% Flat
Warren 62.4% 69.7% +7.3%
Buttigieg 66.5% 66.5% Flat
Harris 54.7% 64.0% +10.7%

It is hard for Biden to improve his position much given where he is, but the movement of Virginia in the blue direction helps the other three Democrats with poll results, with the most significant boost going to Harris.

And that is all for this week.

Trump Internal Polls All Good News For Biden

Since the last update, 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 ABC and then NBC. The full internal polling reportedly included 17 states and matchups against multiple Democrats, but the leaks so far only include 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.

This 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 poll 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:

  • This 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
  • 1𝜎 (68.3%) range: Biden by 168 to Biden by 56
  • 2𝜎 (95.4%) range: Biden by 220 to Biden by 12
  • 3𝜎 (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.
