I think Trump will turn to depending on the average disgruntled and pissed off Americans that make up his base.The big donors will decide who they’re backing as usual. Trump has lost them a ton of money since 2016. I can’t see them doing it again.
My best guess is that Trump will try to ride enough popularity right up until it becomes obvious that he's not going to be the god's chosen one, then he will turn to promoting violence with his 'extremist boys'
You know he's not going to just give up and walk away with his head down!
