Geopolitically I think it'll be a mixed bag. It's not like Trump will be straightforwardly worse than the Dems are/would be. But broadly not much different. The president doesn't tend to have much say in foreign policy, in reality.
He may pull back from Ukraine but that's got to happen at some point anyway. Russia will lop off some territory, the west will gobble up all the remaining assets as payment for war debts and Ukraine will be the worst possible version of fucked (other than prolonging the war).
But I agree with WIlliam that the biggest danger is the judicial stuff. That's not really Trump, that's something the Republicans have been working on, openly, for decades (and the Dems have utterly failed to respond to). They realised they can bypass congress and use the judiciary to make policy. That's going to mean more ultra-conservative regressive nonsense and more culture war bullshit distracting everyone from actual politics. And we're bound to follow them down that hole like we always do.
I mean, yes! They've been at it forever at least since Nixon's days. One of the main movers and shakers during Trump's last presidency was Mitch McConnell. His main task seemed to be travelling the USA organising loyalist judges in local courts. It's a Republican thing that they make no effort to conceal. It's not as though Trump and McConnell even like each other, it comes naturally like supporting capital punishment and opposing public spending (sorry, I mean spending on the public. Giving billions to fellow travellers is fine).
Yup. I don't even think Trump is meaningfully Republican. I don't think he really *has* any particular politics. When he spoke about political issues pre-2016 it was always just regular middle-of-the-toad (leaving that) moderate stuff.
I think he just follows the path of most attention and has ended up here.
He has the emotional maturity of a 13-yo, like so many of his ilk. He is being used by far more sinister, and focused elements, he's their perfect vehicle, a vain, preening, empty vessel.
FWIW a friend of mine from Toronto (not Mr Smith this time) sent me this link. It's an interesting take on things and it has several things I agree with, but I can't help feeling it's a bit like the man persuading himself that his symptoms are just a virus or something: nothing bad.
