Rubio is the biggest Establishment threat to Trump/Cruz right now. If it takes a chubby slimeball to knock him out, so be it.
There will be no “Trump/Cruz.” Trump will choose a liberal like Kasich or even a Democrat just to shock people. You watch. Or maybe he will choose another reality TV star. No possible way he will choose Cruz. He can’t. Remember he thinks he is not qualified. He thinks he is a maniac.
Don’t sell Trump with the promise of Cruz. It won’t happen.
