TPM Wraps up the Tracking polls:

Obama Over 50% In The Poll Of Tracking Polls

Here's a wrap-up of the four major national tracking polls for today. With one new day of post-VP debate data within these three-day tracking polls, Barack Obama's lead is just getting wider:

• Gallup: Obama 50%, McCain 42%, with a ±2% margin of error, compared to a 49%-42% Obama lead yesterday.

• Rasmussen: Obama 51%, McCain 45%, with a ±2% margin of error, compared to a 51%-44% Obama lead yesterday.

• Hotline/Diageo: Obama 48%, McCain 41%, with a ±3.2% margin of error, compared to a 48%-42% Obama lead yesterday.

• Research 2000: Obama 52, McCain 40%, with a ±3% margin of error, compared to a 51%-40% Obama lead yesterday.

Adding these polls together and weighting them by sample sizes, Obama is ahead 50.4%-42.7%, even wider than his lead yesterday of 49.9%-42.5%. And more importantly, Obama is now over the 50% mark.
