This page is a good one for political junkies:

I check it pretty regularly. This link, in particular, is germane to what we are discussing:
https://www.nytimes.com/live/2020/presidential-polls-trump-biden/biden-leads-by-enough-to-withstand-a-polling-misfire
For the first time since we started our poll tracker several weeks ago, Joe Biden leads by enough to withstand a repeat of the polling error in 2016.
If the polls were exactly as wrong as they were four years ago, Mr. Biden would hold the Clinton states and flip Michigan, Pennsylvania, Arizona, and Nebraska’s Second District, giving him more than the 270 electoral votes needed to win.
I like the NYT's presentation, their web interface is the best by far on election night. But, I remember that the NYT model had Secretary Clinton at 99% right before the 2016 election. Sam Wang (NYT) attacked Nate Silver's more measured analysis, and Silver (in my opinion) schooled Wang on how the NYT was misapplying the data. Do you recall that Wang had to eat a bug on live TV after the election? https://www.nytimes.com/2016/11/19/opinion/why-i-had-to-eat-a-bug-on-cnn.html
This is not to say that the NYT has it wrong again, and indeed, the graph incorporating a 2016 sized polling error is very compelling. My faith is in 538 though. They have earned it over several election cycles, including 2016, where they were wrong, but by a rational margin, and totally able to explain why they were wrong.
You are right about one thing. If I am betting straight up today my money is on Biden. No hesitation whatsoever making that bet.
