Let's face it, outsmarting and out-joking Kerry isn't exactly the hardest thing in the world to accomplish.
Let us not forget that Kerry, if my info is correct, failed to get into grad school and he knew his draft number was coming up, that's why he 'volunteered' for military service. He has a lawyer's cunning about how to turn the rules to his favor, but not the deeper intellect needed of a true leader.
