Gallup had a horrible methodology that caused their polls to be way out of line with reality. All of the other polls have consistently said that it is neck and neck.
If anything, [link|http://www.electoral-vote.com/|http://www.electoral-vote.com/] indicates Bush has been doing better recently. He's leading, and most of the states that are close to flipping sides are in Kerry's camp. Of course that could change quickly after the debates start tomorrow night.
