You realize he's saying people should go out and vote and not think everything is fine and don't vote right? Are you not going to vote now?
Moore is right that people should go out and vote but he's wrong about basically everything else in that article, so
1) There's no evidence of a "shy Trump voter effect" in the polls. This is an invention of republican pollsters.
2) Trump hasn't "significantly tightened" any of the swing state races. Moore cherry picks a single outlier high poll of +16 in MI in July and then compares it to the current RCP average of ~7 points to say Trump has closed the gap. Nonsense. If you look at the averages on 538 for Michigan, Biden briefly peaked at 10ish points ahead in the average and he's now down to a meager (/s) 8ish points ahead in the average. Biden has not dropped below a 6 point lead in MI since April and there's never been any significant tightening. This is the story of the entire race.
I think the only place where you could make a "tightening" argument is in Florida, where there was a stretch over the summer where the polls suggested a 6ish point race but it's now closer to a reasonable Florida margin of 2.2 points. I don't think anyone should have expected a 6+ point presidential margin in Florida since the state is very inelastic and typically sees things in the <2 point range - 6 points would've been the biggest margin in like 30 years.
3)"Moore continued, "But I wake up every morning with the assumption that Trump believes he's going to win and that's good enough for me. If he thinks he's going to win, then I think he's going to win."
This is a pretty goofy assumption since it's pretty clear Trump thinks he will lose and that's why he cancelled his election night party, had a low-energy rally where he left after 20 mins, and spends the night ragetweeting at 3am about how the supreme court needs to steal the election for him.
