If a majority of the delegates go for some other candidate, sure. Why shouldn't it be that way? If candidate A gets the most delegates but not a majority, and the delegates for candidates B and C are a majority, and they agree to settle on one of their candidates, what is wrong with that? It's majority rule.
In that scenario a majority of the delegates are for someone other than candidate A. Why shouldn't they have their say?
So you are fine with the GOPe making a backroom deal to put their candidate in place of someone the people picked? Unbelievable.
