Well, a significant number of Trump supporters will walk if the GOPe screws him out of the nomination.
Sure, if it's Jeb or Christie, I agree, I'd walk too. But there are still conservative options besides Trump.
Sure, if they win the primaries. I’m saying if Trump wins 35-40% of the votes and delegates, and nobody else has more than 10-15%, but they keep it from him. Say to Walker. Now I wouldn’t have any problem voting for Walker if he won the primaries, but in that situation, I would.
