As for trump an interesting fact, he is the first president since Jimmy Carter not to go to war with any country, if Biden and Harris get in will there be more trouble in the middle east as they probably won't leave them settle their own problems which was the trump strategy, isolationism.
This is the most important thing about the Trump presidency, and while Hilary Clinton was a far more qualified candidate and I never understood much of the animus against her, she would likely have dragged the US into a war over Syria, which would have been a disaster.
As I have said here before the crises of the Trump presidency have been mostly domestic, for which we can all be grateful.
