Do any Republicans really think Trump won't be the nominee?

I don’t mean just jelly Republicans, I mean any in America? I don’t care what the rules are, don’t you think it will be chaos if they “appoint” someone else?

Talk about the world looking at us like we are hypocrites and corrupt. How can we ever again call ourselves a democracy? I guess the Republicans can argue we are a republic not a democracy. We are both actually.

The will of the people is obviously for Trump. Even if you combine delegates for Kasich and Cruz, sometimes Trump wins anyway in a lot of states.
