IMO, everything will work out like it should. If DeSantis decides to primary Trump, we will see who wins and vote accordingly. Personally I think many challengers will have 2nd thoughts the closer the vote comes. If we have the usual suspects they will learn their fate very quickly. I predict Trump will start with 30%-40%+ with a 5 man field. DeSantis will do very well also but the rest will have under 5% and drop out in a couple of months.
Frankly I'd hate to loose DeSantis as a Fla. governor right now. IMO, Trump will win again and they will try to prove he killed the dinosaurs with pollution.
I can't think of anything else not investigated.
