Democratic presidential candidate Bill Richardson spoke in Seattle on Thursday:
Richardson is a former congressman, U.S. energy secretary and ambassador to the United Nations. He says the race should be about qualifications and experience.
That experience, he said, convinces him that Democratic congressional leaders are taking the wrong approach to Iraq. He said that with timetables for withdrawal now out of the equation, Congress should instead vote to “de-authorize” the war, essentially repealing the Iraq war authorization.
“Since there are no weapons of mass destruction, there is no support of the American people for this war, you de-authorize this war,” Richardson said.
Nothing would make me happier, but I don’t think congress has the sand.
Metaphor 
I've blogger about this concept before, in response to Hillary?Byrd's proposal to "deauthorize" the war. It makes perfect legal and political sense to me, in particular because it doesn't cut off funding for the troops directly, it simply makes Bush's continued deployment of the troops illegal under US law. A perfect solution, which, when coupled with the Kofi Annan's announcement that the invasion was illegal under international law, opens the war for proscecution of Bush/Cheney for war crimes.
