David Brooks summarizes the factions within the Democratic Party, when it comes to the future of Iraq, and why "this is a party teetering on the brink of full-bore liberal isolationism." He thinks there are three camps: One, the Pelosi Democrats; two, the Evan Bayh Democrats; three, the Cantwell Democrats. He adds a fourth, the Clark Demos, these are too mealy-mouthed to take a stand either way.
