Something rubs me the wrong way about Paul. I don't like his voice or speaking style. But on a more substantive basis, I don't think he can possibly hold together the coalition of libertarians, tea party, isolationists, social conservatives, and neocons he's aiming for. He needs the social conservatives and neocons, but I just don't see them getting on board. That would be a disaster worse than what happened to Romney. Thus, if I had to choose between Cruz and Paul, Cruz is more electable because he hasn't gone so far out on the libertarian/isolationist wing.
