TOSsers are hating on Rush even though he's gone full Trumpster because he was late to the game. They're a fickle bunch.
Being a regular Rush listener for a two decades I never did hear him say anything negative about Trump. He didn't all out endorse him because he never endorses anybody in the primaries. But Trump has so many negatives and Rush said next to nothing about them.
That led me to believe he was a lot closer friends with Trump than he led his listeners to believe. Or Trump has something on him.
I think Rush, unlike Hannity, knows the score (about Trump), but now he's so far into Trump's campaign he can't see a way to back out.
At any rate I don't listen to Rush nearly as much as I used to. He can still be entertaining when he's talking about current events or slamming Dems. But when he goes on about Trump, I can't take it. Now I listen to Rush only a few hours a week.
