Ron Paul is deeply square, and every bit as deeply committed to your right not to be. "I don't gamble, but I'm the gambler's best friend," he says, boasting of his support for online casinos. He is a Second Amendment absolutist who doesn't own a gun. "I've only fired one a couple of times in my life. I've never gotten around to killing anything." It's an impressively, charmingly principled world view, though sometimes you've got to wonder how much Paul has in common with many of the people who support him.
