Trump’s Chances Are Dwindling. That Could Make Him Dangerous.

The article begins by describing what is already known, Trump is losing or in worse shape than he was in 2016 in most of the "swing" states. It then goes on:
To be clear, none of this means that Trump’s chances are kaput. As of this writing, our forecast still gives him around a 21 percent chance of winning the Electoral College. That’s not great, but it’s a lot better than zero.

But it’s possible Trump’s chances may decline further after post-debate polling begins to roll into our forecast. Furthermore, the mere passage of time helps Biden in our model, because every day that Trump doesn’t gain ground is a day when his fate becomes slightly more sealed. (Lots of people have already voted!) Case in point: In an election held today — Trump has no more time to make up ground — his chances would be 9 percent, not 21 percent, according to our forecast.

Let’s back up for a second. This is FiveThirtyEight’s fourth presidential election campaign. And in the previous three, there was at least some question about who was ahead in the stretch run of the race. John McCain, for instance, briefly pulled ahead of Barack Obama following the 2008 Republican convention, and Obama didn’t really solidify his lead until early October. In 2012, national polls were very tight between Obama and Mitt Romney following the first presidential debate, and remained fairly tight thereafter (although Obama always maintained an Electoral College edge). And people forget how close the 2016 race was for stretches of the campaign; it was not such a huge upset. In fact, Hillary Clinton led by only 1.4 points in our national polling average heading into the first debate that year.

But there isn’t any of that ambiguity this time. Since we launched our general election polling averages on June 18, Biden has never led by less than 6.6 points nationally. Literally only one national poll — a Rasmussen Reports poll that put Trump ahead by less than a full percentage point — has shown Trump leading by any margin during that period. It’s been an exceptionally stable race.

A big polling error could help Trump … or Biden
One of the misconceptions I hear about FiveThirtyEight’s forecast is that “it assumes that polls are right.” Actually, in some sense the whole purpose of the forecast is to estimate the chance that the polls are wrong. In 2016, the polls did show Clinton ahead, but between tight margins in tipping-point states and the large number of undecided voters, there was a fairly high probability — around 30 percent, according to our forecast — that Trump was going to win anyway.

So while a polling error is possible — indeed, our forecast assumes there’s likely additional error this year because of an uptick in mail voting — it would still take a bigger error than in 2016 for Trump to win.

Assume that current polls hold until Election Day, and subtract 3 points from Biden’s margin in every state (roughly the average error in swing state polls in 2016) … Biden still wins Pennsylvania, Michigan and Wisconsin fairly comfortably, and therefore, the Electoral College; he’d also be a slight favorite in Arizona. And as our friends at the Upshot have calculated, even if you had a polling error of the exact same magnitude in the exact same states as in 2016, Biden would still win, albeit narrowly.
