Trump is the incumbent Republican. Primarying him will only hurt, in this case he will win in the end. Ask Gerald Ford. Ask Jimmy Carter. It will also ruin Desantis's chances to EVER be POTUS. The only reason you want a primary is you don't want Trump, which makes you a complete anal pore.
Instead of debating facts which you were doing you resorted to insults which is sign of either ignorance or a personality disorder
Jimmy Carter and Gerard Ford got primaried because they were terrible and deserved to be primaried, which is why JFK jr. is running
Regardless of what anyone thinks Trump is not the incumbent, he was in 2020 but he isn’t now
