I read what some other posted here about Ron Pauls previous record on immigration (I think this was the forum ), and there was a time when Paul was a Libertarian that he fell more closely with that camp. Here is an exerpt from something I read on Buchanans site:

While Paul considers himself a staunch free trader, he opposed CAFTA and deplored its predecessor, NAFTA. Paul explains, “I was on the side of the protectionists, and I’m not a protectionist. It’s not true free trade. It’s special-interest trade. It’s managed trade. … I didn’t like the trade deal because it was another level of government and a loss of sovereignty.â€
