First of all, I'm mildly disappointed by last night's results, but it doesn't hurt the way what happened on Oct 19 hurt.
It will be interesting to see what effect yesterday's vote has on Iraq and foreign policy generally. I suspect it will be a lot less substantial than people like Joe Higgins are hoping. My sense is that those Democrats who have 2008 Presidential ambitions will not be loudly proclaiming defeat by urging withdrawal, but rather they will want to push the White House towards a winning strategy.
