from TPM Election Central by Eric Kleefeld

Here's our daily composite of the five major national tracking polls. Barack Obama's lead may have contracted slightly since yesterday -- but the overall difference is very small, and he remains well ahead:

• Gallup: Obama 50%, McCain 43%, with a ±2% margin of error, compared to a 51%-42% Obama lead yesterday.

• Rasmussen: Obama 51%, McCain 45%, with a ±2% margin of error, compared to a 52%-45% Obama lead from yesterday.

• Hotline/Diageo: Obama 49%, McCain 41%, with a ±3.4% margin of error, compared to a 50%-40% Obama lead yesterday.

• Research 2000: Obama 53%, McCain 40%, with a ±3% margin of error, compared to a 52%-40% Obama lead from yesterday.

• Zogby: Obama 49%, McCain 43%, with a ±2.9% margin of error, compared to a 48%-44% Obama lead yesterday.

Adding these polls together and weighting them by the square roots of their sample sizes, Obama is ahead 50.4%-42.8%, a lead of 7.6 points, compared to a 50.8%-42.5% Obama lead yesterday.
