The four major national polls indicate that Obama is maintaining a slight lead over his republican counterpart. TPM reports on the poll disparities between the two candidates.

Eric Kleefeld from TPM provides a sample from the polls:

“Here’s a wrap-up of the four major national tracking polls for today — the first day on which we’ve gotten three-day tracking polls that were taken entirely after Friday’s debate. Barack Obama continues to hold a big lead.

• Gallup: Obama 49%, McCain 43%, with a ±2% margin of error, compared to a 50%-42% Obama lead yesterday.

• Radmussen: Obama 51%, McCain 45%, with a ±2% margin of error, compared to a 50%-45% Obama lead yesterday.

• Hotline/Diageo: Obama 47%, McCain 41%, with a ±3.2% margin of error, compared to a 47%-42% Obama lead from yesterday.
