Do you honestly think the establishment is going to select
Cruz as the nominee in a brokered convention?
Didn't you read the article? Why do you think Cruz is working so hard to get as many of his supporters selected as delegates as possible? If he can get a majority of the delegate slots filled with his supporters, regardless of who they are obligated to vote for on the first ballot, then there is nothing the GOPe can do about it.
