Suicide.
Not for DeSantis, this would get him votes. It's suicide for Trump.
a) He'll never be able to leave the state again. I say this without evidence, but I'm still 87.26% sure that getting on an airplane when there's an arrest warrant out for you isn't going to go well. Yes, including private jets.
b) Even if he does hide in his bunker, crying into his ice cream, there go his NY assets. NY will
immediately move on what @
Kellhound would call a "vendetta" by which he means "taking legal action that I don't happen to agree with" on everything taxes from the last 25 years. Again, I don't know the legal rules for this, but I'm pretty sure such a case would require Trump to take the stand -- and would be all the excuse needed for a directed verdict when the defense says "Your Honor, my client refuses to appear on the grounds that he'll immediately be arrested for treason".
c) And then there's that fun little issue with the Mar-a-Lago rules about living there. Heh. I'm pretty sure the locals, who
hate him, are within their rights to say "there's a clause in the contract that says no harboring fugitives, so we're ending your license, come out with your tiny hands up"
d) And, purely for added fun, "aiding and abetting" could be used on literally everyone who walks in the front door indefinitely. Yes, even the taco truck guy.
If Trump tries to hide from this, it'll cost him even more than immediately complying, plus the fun for the whole family of seeing dragged, kicking and screaming like a spoiled toddler, to a helicopter with NY SWAT members and possibly Mueller.
