James Carville is utterly disconsolate tonight. He appeared on “Nightline” with a trash can on his head. A few minutes ago on CNN, Bob Novak said that love them or hate them, you know what the Republicans stand for, but nobody knows what the Democrats stand for. Responded a clearly disgusted Carville, “You are not just right on ideology, you’re right politically. The Democratic Party is a party in search of anything.”
