My view is that most DeSantis supporters - the rank and file, not the donors - are Trump supporters. The Floridians who like him and the ones who support Trump are the same people. Had he understood that he would never have got into the race. His ego blinded him.
IMHO it’s wise for DeSantis to run in 2024 as a springboard into 2028. If that’s DeSantis’s long game, he should have told Trump that’s what he’s doing and the two agreed not to denigrate each other.
