If Trump wins at the convention, I am almost sure they will run Mitt or someone else as an independent 3rd party. The same thing happened against Reagan in 1980 with John Anderson, a RINO Republican.

Nobody "ran" Anderson. He did it on his own and didn't get many Republican votes. With Bush and Baker on Reagan's team it's just silly to say that Establishment Republicans opposed Reagan once he got the nomination.

The only reason Bush was on the ticket was because that was the compromise the establishment forced on Reagan in order for them to agree to back him.
