You may be right, he's certainly capable of it. But if he doesn't get a majority of the delegates going in to the convention then his supporters are mistaken that he's somehow entitled to the nomination anyway. That would be a case where a majority of the delegates were for someone else, and those delegates have a right to agree to pick one of their own candidates if that's what they chose to do. The contest isn't about just getting more delegates than everyone else, it's about getting a majority.
If the GOPe takes your attitude, watch the swing state and blue state congressional districts. Enjoy the rat House and Senate.
