Libertarian Radical
I would think that he would if they tried to push Jeb through. Trump clearly hates Jeb, and the only way Jeb is getting the nod is through chicanery. I think he actually likes Cruz, and if Cruz were to win the nom it would have to be through legitamite votes because the cheaters aren't going to cheat for Cruz.
Trump is "Team Hillary." His job is to be a spoiler and split the vote so that Unelectable Hillary is elected.
