Sycasey, what's your current favorite polling sources telling you?
I think I've already described above: I think it will go about as FiveThirtyEight has it.
https://projects.fivethirtyeight.com/2020-election-forecast/Biden wins by about 8 points nationally and gets the Hillary states, plus MI, WI, PA, AZ, then (less confidently) NC, FL, GA. In a really big wave he could get IA, OH, TX. He also wins Nebraska's 2nd district. That's about a baseline of 290 electoral votes for him, with an upper bound of 400+ if he beats his polls by several points.
Polls could be wrong in either direction, but IMO it's more likely that they are wrong in Biden's favor. Why? Two reasons: (1) turnout is clearly high, which tends to favor Democrats in recent elections, and (2) Democrats have banked a ton of early votes already, pretty much across the country. That leaves Republicans needing massive turnout on Election Day to counteract the early vote. It's not impossible (see: Florida 2016) but it's a tough task with an unpopular President, COVID outbreaks happening, etc. If people haven't voted yet you can't be sure they will show up.
But what about 2016? Didn't Trump beat the polls then? Yes he did, but there are a lot of reasons why it's different now. For one thing, Biden's polling lead is bigger. The secondary indicators that might tell you an upset is brewing also aren't there this time. In 2016, the national polls tightened in the last couple of weeks. This year they are pretty static. In 2016, a lot of the close Midwestern states weren't polled much in the last week so that late movement went undetected there. In 2020 we have a lot of polls in the battlegrounds, and they are likewise pretty steady with a Biden lead (on average).
In 2016, this guy Dave Wasserman was telling everyone that he was looking at the smaller district polls run by the parties/campaigns and they were showing a lot of trouble for Hillary in white working-class districts that didn't seem to be captured in the statewide polls. This year he says
he's seeing data in those districts that basically confirms a big shift away from Trump. He's saying stuff like this:
If those states are tossups that's very bad for Republicans.
There's other stuff. In 2016 neither candidate was over 50% in polls at any point, including in the major battleground states. This year Biden routinely polls above 50%, particularly in MI, WI, PA. That indicates there aren't as many undecided voters now. In 2016 late deciders broke heavily for Trump in these states, but this time he'll actually have to flip voters or get a massive surge from his own new voters to counteract that.
Most of the arguments in favor of Trump winning basically amount to wishcasting. "The polls are wrong!" "We'll see a huge surge on Tuesday!" "He's doing better with black voters!" Picking out individual polls that look good for Trump but don't represent the majority. Stuff like that.
So that's why I think Biden probably wins comfortably. Nothing is guaranteed, but there would have to be a really big polling miss for Trump to win.
