An updated list for our pocket. Once again, I bet at least 70% of the people on this list end up supporting Trump by November. Either they will find some justification for their flip-flop (probably pointing to some random thing that Clinton and/or the Democrats did) or they won't explain the change at all. No matter how it goes down, at least 70% will fall in line.
I'll make this a series as prominent GOPers make their #nevertrump pledge and then check my answers in November.
