But I do think the GOP and others are using him (and you) to keep Trump from getting the nomination and sending it to a brokered convention.
It's a primary. Just because Trump is ahead by 230 delegates does not mean that he has won and everyone else should drop out. And if he eventually loses, it doesn't mean others stole it, it means he got beat. Of COURSE Senator Cruz is trying to keep Mr. Trump from winning, that is what he SHOULD be doing. I'm personally very pleased that Trump seems to be helping him so well.
If he can't stand the heat, get out of the kitchen. Judging from his behavior over the last week and especially last night, he can't handle the campaign. Is this how he will handle the job?
Last thought - if Cruz and Kasich would both put on their big boy pants and announce a Cruz / Kasich ticket today, it would be nearly a tie in the delegate count and they would have a very positive message to send about how they approach inclusion in their campaign.
