I don't much like Ron Paul, but he's never come across as racist to me.
His schtick does attract a bunch of yahoos and racists and tinfoil hat wearers, but I don't buy that he himself is one of them.
Here's a post by Paul on racism in the wake of Trent Lott. I just don't see the same guy who wrote this also writing some of that other stuff. It doesn't add up.

Again, I'm not a fan of Paul. He's my second-favorite Republican currently in the race, but that's extreeeeemely faint praise. But it bothers me when people jump to believe the worst about a guy who seems basically decent, if misguided.
