Summary of the day's trackers

We are following six trackers here at Clintonistas for Obama, and here is the Obama spread on each of them:

Research 2000/Daily Kos, Obama +5
Rasmussen, Obama +5
Hotline, Obama +6
Zogby, Obama +7
Gallup Expanded Likely Voter Model, Obama +7
Washington Post/ABC, Obama +8

Talking Points Memo observes:

Adding these polls together and weighting them by the square roots of their sample sizes, Obama is ahead 50.5%-44.2%, a lead of 6.3 points, compared to the 50.2%-44.4% Obama lead from yesterday.

In other words, Obama with an increase of 0.5 today more than made up in the trackers today what he lost yesterday (0.4). All of this is statistical noise.
