The Washington Post Tracking Poll

The Washington Post/ABC tracking poll says that Barack Obama maintains the same nine point lead he had yesterday over John McCain:

Obama 53
McCain 44

The Post observes the continuing enthusiasm gap between supporters of the two campaigns:

As Election Day creeps closer, Obama's supporters are expressing near unanimous enthusiasm for his campaign, while McCain's backers remain more reserved. Seventy-one percent of Obama backers said they feel "very" enthusiastic about the campaign and 97 percent feel at least somewhat fired up about his candidacy. Among McCain's backers, 88 percent said they were enthusiastic, but far fewer, 39 percent, were decidedly so.

So to sum up, we're following six tracking polls. Obama's margins of victory over John McCain in each of these polls are these:

Gallup Expanded Likely Voter Model, Obama +7
Hotline, Obama +7
Rasmussen, Obama +8
Washington Post/ABC, Obama +9
Zogby, Obama +10
Research 2000/Daily Kos, Obama +12

Talking Points Memo observes:

Adding these polls together and weighting them by the square roots of their sample sizes, Obama is ahead 51.6%-42.8%, a lead of 8.8 points, compared to the 51.6%-43.1% Obama lead from yesterday.

Obama continues to put traction between himself and McCain; yesterday, the margin between the two men was 8.5, so we're up 0.3 over yesterday.
