Trump is a problem for the GOP. He has them over a barrel.
They can't get rid of him because they'll lose the crazy vote, and for sure, the crazy vote is about the only thing keeping them in the game right now.
And he gets to order them all about. And the GOP are a bunch of rich white me, and rich white men do not like that kind of thing. They like being the ones ordering people about. It's the natural order of things god damn it.
Their only real way of getting rid is either an assassination, or at least looking the other way when somebody else tries it. That way they get to keep the crazy vote. "Do it for Him" they'll cry. And they will. Either that or wait for the inevitable cardiac arrest to take him. But a man who dies on the toilet is going to get a lot less sympathy than if he's shot by an Obama loving abortionist.
The problem is that everybody sitting around that table thinks they're skilled enough.
