Mid terms didn't go the way the Trump supporters wanted and now DeSantis, someone most Trump supporters liked, may or may not challenge Trump. The anticipation must be killing them. Their other big problem seems to be accusations of being establishment, which basically means having been in the system in any way shape or form before Trump. Accusations of being a Glowie abound.
On the other hand, fans of DeSantis seem to live in a magical world where the President can just wave a wand and do all the same things.
Disney was extremely exposed in Florida, so DeSantis could take advantage and remove the insane special district they had.
DeSantis has majorities in both houses and a strong mandate from the Midterms, so he can pass anti rainbow legislation
DeSantis has direct control over things like boards across the states, like at New College of Florida, so he can unilaterally wipe the boards clean
Trump had none of this available as president, and the items he tried would be blocked in the ninth circuit the next morning. Requiring a slog through the courts to move forward.
