Well, Rubio would belong on that ticket regardless of some GOPe conspiracy we think might be at work; You have a juggernaut in that pairing. It’s smart politics.
Cruz/Rubio would be a dynamic ticket, as long as Cruz kept a sharp eye on the oh so slick Rubio; I would trust him in a Cruz administration as much as I trusted GHW Bush (and his minions) in the Reagan administration.
