Personally, I'd be putting moving, or just travelling, to the US, alongside moving to China, or NK, or Russia in the fucking dumb ideas bucket.
I genuinely think that US society has no grasp whatsoever about what is about to happen to it - I think it has had it's last meaningful Presidential election for well over a decade, and that the scale of things like disenfranchisement, de facto abolition of rule of law, destruction of de facto political freedoms and all the other norms of ademocratic/liberal political system is going to rival that seen in Germany between 1933 and 1939.
In fact I would be surprised if internment camps for political/legal enemies of Trump/his successor aren't a thing by 2028 - the only light in this darkest of timelines will be the solid possibility that many of those who said that Harris was sufficiently poor on 'left' issues that voting for her/against Trump wasn't worth getting out of bed for, will get to sample the joys of a Nebraskan winter from behind barbed wire.
If I was Biden, or Harris, or any publicly known Democrat - or people like Liz Cheney or Mitt Romney on the Republican side - I'd genuinely be looking at places I might get political asylum.
