Sarah Palin gave a typically fiery speech in support of John McCain’s re-election campaign today in Arizona. At one point, she was interrupted by a heckler, but he was quickly overwhelmed by the roar of the crowd and eventually escorted from the rally. Responding to the heckler, Palin said, ‘Young man, stick around and listen to what we’re going to say. Sir, maybe you’ll learn something.’ I doubt it, learning something from Sarah Palin? What can she teach anyone?
