I'm not, nor have I ever been, a Democrat. I suspect, though, that you've always been clueless.
I don't give a shit whether Trump runs again. If he survives his steady diet of Big Macs w/fries (with a Diet Coke or Coke Zero or whatever they call it now - - hilarious), makes it to 2024, runs and gets the nomination, he'll lose in the general to anyone not named Biden, Harris or Clinton.
Long term, though, it really doesn't matter whether he's the Republican nominee in 2024 or not. The damage to the party is done. That will become even more evident in the next couple of weeks. The Election Deniers look to do well on Nov 8. And at least some of those who lose close races will create chaos.
