Barack Obama's attitude in Monday night's debate spoke more clearly than anything he said. No, he didn't laugh like Bozo the Clown, giggle like a schoolgirl, shake his head, and roll his eyes like Jokin' Joe did. But he looked petulant, perturbed, and on edge (and was occasionally rude) throughout much of the night, despite three days of debate preparation at Camp David. It seems Barack Obama just can't help himself.
