Last tracker of the day

The last tracker of the day is in. The Washington Post shows Obama lead by nine points (±3%):

Obama 53%
McCain 44%

These are the same numbers from yesterday.

So this is the summary from the day:

Rasmussen, Obama +4
Hotline, Obama +6
Research 2000/Daily Kos, Obama +8
Zogby, Obama +8
Washington Post/ABC, Obama +9
Gallup Expanded Likely Voter Model, Obama +10

Talking Points Memo comments:

Adding these polls together and weighting them by the square roots of their sample sizes, Obama is ahead 50.5%-43.1%, a lead of 7.4 points, compared to the 50.5%-43.7% Obama lead from yesterday, when the ABC/WaPo numbers are included in yesterday's total.

In other words, Obama may have increased his lead by 0.6 from yesterday.
