He has a total of 10. Looking at number 2 above, if you normalize the polls to a more reasonable divide of the electorate McCain is right there already. Certainly the Palin rallies indicate the enthusiasm is there with conservatives wanting to defeat the evils of liberalism.
This is why it might happen. Not saying it will.
1) One poll has undecided voters at 14 percent on the last weekend, which means most of them probably really aren’t undecided, that they are either going to stay home or vote preponderantly for McCain and pull McCain across the finish line.
2) Most pollsters are claiming the electorate this year is six to nine points more Democratic than it is Republican. That would be an unprecedented shift from four years ago, when the electorate was evenly divided, 37-37, Republican and Democratic, and a huge shift from two years ago, when it was 37-33 Democratic. A shift of this size didn’t even happen after Watergate.
3) Obama frequently outpolled his final result in primaries, which might have many causes but might also indicate that he has difficulty closing the sale.
4) The argument in the past two weeks has shifted, such that many undecided voters who are now paying attention are hearing about Obama’s redistributionist tendencies at exactly the right moment for McCain.
5) The tightening in several daily tracking polls indicates a modest surge on McCain’s part that could continue through the weekend until election day. If he is behind by three or four points right now, a slow and steady move upward could push him past the finish line in first place.
8) What happened with the Joe the Plumber story is that Obama has now been effectively outed as a liberal, not a moderate; and because liberalism is still less popular than conservatism, that’s not the best place for Obama to be.
