This Reuters article (h/t Drudge) on the NIE report has this throw-away paragraph:

Democrats, trying to win control of Congress from the Republicans, have focused on the Iraq war, which is increasingly unpopular with the public.

The only problem: The last three Gallup polling periods actually show a decrease in those that think it was a mistake to go to Iraq. Right now, Americans are split 49%-49%, the lowest point since last December and down from a high of 57% in March and April ‘06. Oops.
