Funny, how people are more concerned about hypocrisy, real and imagined, than about genuine evil. Perhaps you ought to look into what it takes to be an elected politician. The key thing for purposes of considering your empty accusations of hypocrisy is that his job is to represent the interests of his constituents, which aren't mostly not libertarian in viewpoint, not merely advocate a particular ideology with pure consistency.
I notice that no one bothers to point out the hypocrisy of the vast majority of US politicians here. Somehow Rand's hypocrisy is far more significant than the hypocrisy of a Reid or Shelby, to name a couple which I've noticed. I think it's a terrible idea to leave politics to the completely venal, but this sort of attitude remains strangely commonplace.
One would have to be a fool to eschew a strong libertarian (or whatever philosophical traits one deems desirable) candidate on the basis that he isn't ideologically pure while ignoring that he has a job that demands a lot of things over ideological purity. Especially when his supposed hypocrisy is not notable compared to background noise of the group he is part of.
