F off Ann Coulter. Nobody cares that you, for whatever reason, are trying to sound reasonable now. You've spent an entire career being a right-wing fascist. There must be some money angle in it for her to be going after Trump (who is hardly too extreme for her) but I hardly care why. It might simply be that she thinks he can't win the election, or prefers Desantis' brand of fascism.
That "if you go after me" sentence is as clear a threat as you can get. There's still the Southern Suburban Irregular semi-elite tactical brigades out there, who will gladly follow their leader into war (ok, precede because that particular general won't be at the front) as long as there are no obstacle courses and actual running involved. And as mentioned, there are always solo "patriots" who might be willing to rid trump of this meddlesome priest.
If Trump does win the general election, there's a lot of people who should do one thing: emigrate, and in a hurry. Trump is going to do his best to put public hangings without a jury trial back in place, and if it's up to the GOP parts of Congress or Supreme Court to stop him, that's not a given. You know he's got a giant growing list similar to Arya in Game of Thrones and he probably recites it each night before beddy.
