Before the war, a majority of the people opposed it. It depended on how the question was asked, of course - a majority didn't oppose any war in Iraq, but a majority did oppose the war we were given (no UN support, etc...).
And, now, 59% of the public thinks going to war was a mistake. Still, that opinion is about as represented in the media as was the 60+ percent who approved of Bill Clinton during the impeachment follies.
Strange how these things work.
