Matt Taibbi writes about how Republican leaders who were fine with George W. Bush in the White House are panicking over the possibility of You-Know-Who getting the job. I think Taibbi is a little harsh on G.W.B., which is an odd thing for me to be saying since I think he might well have been the worst president of all time. Nevertheless, I think Taibbi is onto something when he says, as others have, that the problem the G.O.P. establishment has with Trump is not that he's dangerous to America but that he's dangerous to them.
