Ron Paul

Best: Still Mr. Magooish, but in a good way. Continues to ride an isolationist, small government, lower taxes message that gives him a monopoly on the Perot-Buchanan wing of the party. Remained relatively unshaken by the questioners' apparent determination to make him explain his presence on the stage.

Worst: Mr. Magoo was never elected to federal office.
