There are politicians out there who could...do a great job of restoring liberty and freedom to our country. Ron Paul for one.
Again, if he is one of those people, it's about time he got started. In a republic, it's not enough to have the right ideas (if Paul has them.) You can't just dictate policy. You have to convince enough people to elect you, and you have to get Congress behind you. When Ron Paul figures out how to do that, he'll be restoring liberty and freedom.
Or, he could put his efforts into building a movement (not necessarily a formal political party) that will do that. Yeah, I know; Campaign for Liberty - time will tell.
