I do suspect that, as things currently stand, Trump will win fairly with a few thousand voters, losing the popular vote by millions, like in 2016. But that's just a pessimistic concern about America. Certainly, the polls are far closer than they would be if the American political system were healthy.
In any case, I'm torn because a Trump victory would be a boon for commentators like me (assuming he doesn't start WWIII or a real fascist uprising that harms Canada where I live). But a Trump victory would also be a blight on humanity.
