Seriously, I don't think he is. He is Libertarian to a fault. He is an Isolationist. He is a lessez faire capitalist. Those positions are a far cry from the Neo-Socialism espoused by the Democrats.
I think he would necessarily be different on Religion, Abortion, and Marriage because Libertarians just don't seem to care. Also, he is a strict constitutionalist. -At least as far as I can tell.
He’s none of that, he’s a “Player.” He does what he has to to forward his career. He doesn’t really have principles to anchor him. 35 years from now he’s McCain.
