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

Rasmussen: Obama 52%, McCain 44%, with a ±2% margin of error, compared to a 52%-45% Obama lead from yesterday.

ABC/Washington Post: Obama 53%, McCain 44%, with a ±3% margin of error, unchanged from yesterday.

Hotline/Diageo: Obama 50%, McCain 43%, with a ±3.3% margin of error, unchanged from yesterday.

Research 2000: Obama 52%, McCain 40%, with a ±3% margin of error, unchanged from yesterday.

Zogby: Obama 51%, McCain 42%, with a ±2.9% margin of error, compared to a 51%-41% Obama lead yesterday.
