And they still include the AP 1% outlier. Looking forward to when that drops off in a couple of days. The biggest differential they've had is Obama +8.2%. Of course the real game is electoral votes. Who can get to 270? RCP shows Obama with 306 EVs solid or leaning, McCain with 157, and 75 too close to call. 538.com gives McCain just a 5.1% chance of winning now.
BTW, I figured out what McCain is doing in Pennsylvania. He can't accept the polls are accurate, or there's no point in trying. If he assumes the polls are all biased in Obama's favor by 5 or 6 percent, though, he has a very slim chance. That would put Obama ahead in enough states to have 306 electoral votes, McCain with 232. But Colorado, New Mexico, Ohio, Pennsylvania, Virginia, and New Hampshire would be within a few points of tied. McCain's campaign is pretty much yielding Colorado and New Mexico. Together they only have 14 EVs, and they are so far out west that travel time to campaign there would cost him useful time elsewhere. The other four are close enough together, he can conserve time and money by only visiting them. He has to swing 38 EVs his way. Ohio has 20, Virginia 13, New Hampshire 4, and Pennsylvania 21. Ohio, Virginia, and New Hampshire add up to 37, enough to tie but not to win. So he has to try for Pennsylvania or assume the polls are even more than 6 points off.
Even with an assumed bias of 6%, though, Obama has something like a 4.8% lead in Pennsylvania, and a smaller lead in the other 3. And whatever moves the McCain campaign makes, Obama's campaign can match, or better. Obama can make as many personal appearances as McCain. And he can afford more TV ads. Still, McCain has to try to turn Pennsylvania, or he can't win. And Obama's sizable lead in PA means he can trade visits there for visits to OH, and win both.
Well, McCain can always assume the polls are biased by 8% or more. While he's at it, he can assume pigs (with lipstick) have wings . . .
