I can answer that.
Florida has mostly returned to normal despite some schools fighting his mask mandate ban in the Broward and Palm Beach counties. People generally wear masks in the blue areas or tourist traps, but outside of them and chain places, you would be convinced Corona was more a beer you'd chug at the beach than a global catastrophe.
He COULD be LARPing, but I haven't seen proof of it yet. I give him the benefit of the doubt. Somethings he did that are against traditional big business GOP interests include banning offshore drilling and better funding wildlife preserves, banning troons from competing in sports (on the first day of pride month too), passing vigorous election laws (even when Florida had the best election ever in 2020) and telling anyone madating vaccines to get fucked and see them in court, to name a few. He is no Noem, if thats what your worried about. And if you're worried about "green policies," DeSantis knows we like preservation of the environment here.
Would he be better than Trump? Could he challenge Biden and win? Not sure. He would know what he was getting into with the swamp scum better, but would he be 100% with his voter base? You'd have to take that chance. Electorally, he would be a Romney + Trump combo of appealing to rurals and suburbs alike. The only problem is that they'd wouldn't be as motivated as if Trump was the frontman. The Dems wouldn't be as motivated too, so its an even tradeoff.
