The ABC/Washington Post Tracker sees Obama position improved by one point as McCain loses one in today's tracker:

Obama 52

To sum up the six trackers we are following:

Rasmussen, +3
Zogby, +5

Talking Points Memo observes:

Adding these polls together and weighting them by the square roots of their sample sizes, Obama is ahead 50.2%-44.4%, a lead of 5.8 points, compared to the 50.6%-44.4% Obama lead from yesterday.

Obama's weighted average yesterday was 6.2. If he were to lose 0.4 each day between now and election day, Obama would win by 3.8%.
