I'm not sure the GOP leadership wants them to be friends. I know they hate Trump with a passion, not because of his style or personality, but because he showed them up so badly in how to get good things done. And I am not as certain, but I suspect there are behind the scene whispers of how to neutralize the very very popular Ron DeSantis who might seek to take the place of one of their own.
I appreciate what both DeSantis and Trump have accomplished though and I have always put results and accomplishments ahead of personality and style. If there are a lot of folks like me out there, I think all of us would like for DeSantis and Trump to be friends. Personally I would hate to see DeSantis run in two years knowing how terribly he would be savaged. He is still very young, and unless he has a bullet proof support team around him, it could ruin him. Let him finish out his second term as governor and I think he might be in a better position to weather what they'll try to do to him.
