You should have led off with "Once upon a time......"
Not when the facts justify the statement. Trump is a loser, period. He didn't help DeSantis - he just likes to lie to people like you, who swallow his lies without question - to assuage his own ego.
The fact of the matter is, DeSantis was behind his opponent when Trump visited, and he remained behind his opponent after Trump's visit, and until he had a debate with his opponent, at which point he moved into the lead.
Trump did not do diddly-squat for DeSantis. So even by your own bizarre set of rules, DeSantis doesn't owe Trump a thing. The only backstabbing going on is Trump stabbing DeSantis in the back.
