Don't get me wrong, I hate Rick Santorum. He doesn't even have a libertarian streak. Most politicians at least give lip service to liberty. Rick Santorum basically says "Screw liberty." And he absolutely loathes Ron Paul. While I would still feel a moral obligation to support Johnson (Its a libertarian thing, when faced with two authoritarian candidates I can't really tell anyone to vote for either one) if I were forced to choose between Santorum and Obama, I'd hold my nose and pick Obama. And I'd have done so far more quickly than I did between Obama and Romney.
If I had to pick between Santorum and Ace99, I'd support Santorum. Santorum to my knowledge hasn't supported regulating speech
Don't get me wrong, I'm not a fan of the GOP, but they aren't about restricting speech, obscenity yeah, but while bad that's not nearly as bad as actually censoring political views. Then again, that's just IMO, but attacking the political process itself is worse than banning swearwords.
