Recap of Today's Trackers

Essentially, we're now following six daily trackers, namely, in order of the release each day, Zogby, Research 2000/Daily Kos, Rasmussen, Hotline, Gallup Expanded Likely Voter Model, and Washington Post/ABC News. Today lined up this way:

Hotline, Obama +5
Rasmussen, Obama +6
Gallup Expanded Likely Voter Model, Obama +8
Zogby, Obama +10
R2K, Obama +10
WaPo/ABC, Obama +11

Talking Points Memo observes:

Adding these polls together and weighting them by the square roots of their sample sizes, Obama is ahead 51.3%-43.1%, a lead of 8.2 points, compared to the 50.5%-43.1% Obama lead from yesterday.

In other words, Obama's lead increased from yesterday's results to today's by 0.8%.
