It was DeSantis’s support for the rabid neocon Marco Rubio over Trump in the 2016 primaries that concerns me, as well as a few other things like his receiving large donations from establishment sources. Well if he decides to run he will have the opportunity to clarify his intended foreign policy, but at the moment he is so far behind Trump in the polls that I don’t see him running unless the deep state somehow manages to keep Trump out of the race.
DeSantis supported Rubio, this is true, but then again, so did I... until too many of his positions once attaining office proved to be less than satisfying, to say the least. DeSantis has not commented on this prior support, so who knows if he still feels that way. It's also noteworthy that Donald Trump rallied behind Marco's re-election, and that has been greatly credited with keeping Rubio in office.
DeSantis' position as a more hard-line conservative and traditionalist have increased dramatically since his election as Florida's governor, that much is certain. He has, willfully or no, now placed himself well ahead of almost the rest of the pack, and he shows no sign of slowing down. He often goes on the offensive, which itself is remarkable in this day and age. So, again, I say give him the benefit of the doubt on this 'neocon' and 'MAGA spoiler' stuff -- his deeds are telling the tale.
