Ron Paul is definitely not like other politicians. Ron Pauls message is the same as it has always been. The things he's saying now, he also said in 2008 and 1988. Ron Paul is not a politician, he's a doctor who was elected to Congress. Mr. Libertarian himself, Murray Rothbard (RIP), was a close friend of Ron Paul and he endorsed his campaign in 1988. Ron Paul is nothing like other politicians. Ron Paul has never sold out to the establishment and it is very unlikely that he will do so in the future.
