Actually, I think that question is better put to the Kerrycrats, who SHOULD have been at the forefront of the anti-war on Iraq movement, but cannibalized the movement in order to silence all dissent on the war on Iraq, in order for Kerry to win.
That strategy for questioning Washington worked about as well as any, eh?
It is just plain idiotic to think that the Democratic party will question the war. They voted for it, and continue to vote to fund it.
The only way to effectively question this war is to make the US ungovernable, as was done with non-violent action to stop the Vietnam war.
We don't need to question Washington, we need to shut down business as usual in Washington. Which will begin with the January 20th Counter-Inaugural festivities.
