There may be an open convention or a contested convention, there will not be a "brokered convention." That was in the old days when the State Chairmen controlled and could order delegates to vote a certain way. Nowadays, after the first ballot (in a few cases, 2nd or third), the delegates are free to let their conscience be their guide.

With all the animosity Trump has engendered, he will have the hardest time garnering new delegates. You can only ridicule their favorite guy a half dozen times before they will harden and turn away in disgust. "Hostility," which Donald claims to be a master of, works to get attention, it doesn't help you when you've made their favorite guy a repeated continuous target of junior high hostility.

True. But there will also be some counter-pressure against these delegates to either accept a clear delegate leader or risk open party revolt. If two candidates are very close, I can see more potential for delegates going elsewhere. However if Trump has a commanding lead but only a plurality of delegates, I can see many not wanting to risk complete destruction of the party by going against the primary voters.

Now Mitt is in fantasyland. Following him is following a proven loser to certain defeat and destruction.
