That is all he's got left. Debating tricks. Several times he repeated like a mantra, "Donald and Hillary" as if they were running mates. Nice try, college boy, but way to obvious and off-putting. I too thought for awhile he was coming unglued, but now I realize, Cruz isn't crazy, he's just shallow-- about an inch deep-- this is all he's got.
He's in way over his head. Once upon a time, I thought he might be a competitive contender for president--but the more I learn about him, the less I can support him. He can't give any reason to vote for him, all he can do is complain about Trump. Meanwhile, Trump shows by his quick thinking and deft handling of the press that he is uniquely suited for the job.
I think I first became aware of Trump's intellect when he gave out Lindsey Graham's (I think) cell phone number, and among people whining about that, someone thought to give out Trump's cell phone number to get even with him. Instead of whining and so forth, Trump recorded a message thanking people for their interest in his campaign and directing them to his website. It was brilliant!
It's not just Cruz...Cruz is on a very large team...Cruz isn't fighting for himself...He's fighting for the GOPe...And that team doesn't care if Cruz becomes President, or Hillary, or whoever as long as it is someone on the inside...
