I wonder if there’s a personal element in Rush’s attitude toward Trump.
Did Trump somehow snub Rush in Palm Beach in the past?
On his show Rush will talk about going to the Breakers (and married there), but rarely if at all about going to Mar-A-Lago. (Rush did mention playing golf with Trump, but I don’t recall him saying what course.)
I think there is a personal element. A little Palm Beach rivalry, private jet size envy?, golf, and so on. Rush is proud of his massive audience and maybe is a little jealous that Trump the "barbarian" (non-intellectual, no political experience) put together a movement. Lastly, they both have big egos -- I say that in a positive way. Nothing wrong with it. But maybe they clash.
