Update: Added Obama to the list. He abstained in the anti-MoveOn bill, but his rationale (it was a protest against a ridiculous piece of legislation) was sound.
And since it wasn't clear, this was regarding the anti-MoveOn resolutions. These are the Democrats who refused to throw netroots activists under the bus while aiding and abetting bullshit Republican efforts to distract on Iraq.
