I think you should just vote for a 3rd party, they can suit your needs, who the hell says that you HAVE to vote democrat or republican, up here in Canada we have multiple parties, I think its lame to vote for only one of two parties, because so many people like you get trapped into something you dont want.
I don't know what makes someone a liberal or a conservative, I just go by who I agree with the most. I tend to almost always agree with conservatives and rarely ever agree with liberals.
