I got Bush at -140 so I wouldnt say Kerry is a lock based on the map since so many of the states are so close. I love that site and have been checking it for about a month but those numbers can change quite radically day by day. One interesting study I found on the site was that for a sitting president to win a state he must be ahead in the polls by more than the margin of error since undecided have historically voted 2 to 1 for the challenger,
