Everything else, he's pretty much a loon on. And I think its the height of hypocrisy to declare that one is a libertarian, but they want the government to have the power to force a woman to carry an embryo to term.
That would be more of a constitutional conservative, as he believes it should be state by state. It depends on how you view the embryo, if you believe that it is victimized by abortion, thus suggesting you believe it is a human being, then there could be no other position to take, even if you were a libertarian.
