You are way off base on this one and have nothing to back this up. Ron Paul has consistently been for every American. He is for repealing Roe v. Wade and allowing states to decide on abortion rights, he has been outspoken on the bias of prison sentences and the death penalty on minorities, and is against a federal mandate on marriage. Those positions are exactly contrarian to the ones you are attempting to assign to him.
I'm not sure why you think his understanding of economics is "loony" as he is the ONLY member of congress that predicted the housing collapse YEARS before it happened (http://www.youtube.com/watch?v=mnuoHx9BINc)
Neither Bush nor Obama ever championed liberty. Ron Paul is a completely different animal. He isn't promising to GIVE you anything — he's promising to reduce government to get OUT of your life. Big difference.
