He's going for the Republican nomination. I would hope he's not at the next Democratic debate :p
Anyway, I'd say Ron Paul is the first truely Republican candidate to come around in a long time. Unfortunately, electing him would put our country back into the stone ages, with the elimination of just about every aspect of Federal government that isn't explicitly stated in the Constitution. Of course, he wouldn't have the power to do that himself, with the whole checks and balances system, but he would do his best to prevent Congress from getting anything done that involves spending money.
