DeSantis is pure establishment. He "may" be good for FL but I don't see conservatives in the country gathering around for him.
He talks a good game and has done a few good things, but it's always with an eye towards higher office.
And if you want to know why "conservatives" are going against Vance (and maybe Rubio), it's because of the "RINO" block supporting DeSantis.
That is 100% the truth. RINOs support their own kind.
