Why is Trump still competitive against Biden after everything that's happened?

[MT Treasurer]

As always with Trump, the question is with whom a particular event makes him stronger, his base or his base and a broader electorate? Kavanaugh juiced up Republican turnout and they still got absolutely crushed in 2018 with relatively favorable economic fundamentals/no foreign crisis. Why? Because he and his party's brand were absolutely toxic among vast swaths of the electorate who weren’t part of the base.

I agree that the indictments have made a good chunk of his supporters even more enthusiastic, but there’s absolutely no evidence it’s made him stronger in a general election.

Yes, Trump's base is vocal; it’s really, really loud, it’s super-passionate, but for the umpteenth time — it’s not even close to a plurality of the American electorate. An unenthusiastic Biden vote counts just as much as an enthusiastic Trump vote.
