The polls are going to be proven wrong again.
Except, this time in, the polls will have underestimated Biden's lead, and consequent win.
More young people are voting than 2016 -
This is what gives me hope for tomorrow.*
I've been talking about how I think there's a systemic error in favor of Biden in the polls, due to hostile Trump voters not talking to pollsters. Opposite that, there is what appears to be record voter turnout. Polls aren't really polls anymore. They are survey data that is then weighted to form an esitmate of the result. What I'm hoping is that the "weights" are incorrect because they are based on typical election turnout.
Based on early voting data, election turnout is expected to be very high. I'm hoping that the polls/estimates are wrong because they underestimate the turnout in anti-Trump voting blocks. If that happens, your prediction will be true. Biden's margin of victory will be bigger than it appears, and it will be an electoral college landslide.
If I were a betting man, though, I don't think it will happen. My official prediction as of this moment is that Biden wins with 270 electoral votes. All the "swing states" identified at 538 go to Trump, plus Pennsylvania. That leaves Biden with 270.
And on what do I base that on? Nothing. Just a hunch. A feel. My predictions are utterly useless, but we're here, and talking, and it's fun to put out predictions, even if we aren't supposed to be having fun.
*That is, the literal tomorrow, Tuesday, November 3. As for the broader tomorrow, i.e. hope for the future, I work with today's kids in Robotics. Based on my interactions with them, I fear for our future, but I'll do what I can.
