He does not face a Republican rebellion over Charlottesville. He faces a Republican so-called "leader" over Charlottesville. There's a big difference between Republican and "Republican leader." The leaders have never supported him, and they never will.

Which is why the leaders have to go. I suspect many of them will disappear in the next election. Hope so, anyway. I prefer my enemies in front of me, rather than behind me, saying they support me, all while they are sticking knives in me.
