The Race as of 3 AM Sunday

FiveThirtyEight.com: Electoral Projections Done Right: Today's Polls, 3 AM Edition (11/3): Barack Obama's position has become somewhat stronger since our update this afternoon. We now have him with a 5.8 point lead in the national popular vote, and winning the election 96.3 percent of the time.... Obama's win percentage has ticked upward again for a couple of reasons. Firstly, he's gotten some relatively good numbers out of Pennsylvania since our last update, with PPP and Zogby giving him leads of 8 and 14 points, respectively, and Rasmussen showing his lead expanding to 6 points after having been at 4 before. (The Zogby poll is probably an outlier, but may serve to balance out outliers like Strategic Vision on the other side). Secondly, McCain's clock has simply run out.....

Related to this is the fact that there are now very, very few true undecideds left in this race. After accounting for a third-party vote, which looks as though it will come in at an aggregate of 2 percent or so (after doing some work on this tonight, I concluded that I had been slightly underestimating the third-party vote before), I am showing only about 2.7 percent of the electorate left to allocate between the two major-party candidates. Even if John McCain were to win 70 perecnt of the remaining undecideds (which I don't think is likely), that would only be worth a net of about a point for him. Frankly, McCain's winning scenarios mainly involve the polls having been wrong in the first place -- because of a Bradley Effect or something else. It is unlikely that the polls will "tighten" substantially further -- especially when Obama already has over 50 percent of the vote...
