Poll shows Obama leading by three

A new poll from The Washington Post and ABC News shows Obama leading by 3 among likely voters, and by 7 among registered voters.

National polls over the weekend showed a mixed bag for Obama and Romney. Nate Silver writes at the New York Times:

"As of Sunday, [Obama] was up by 1 percentage point in the online tracking poll published by Ipsos, and by several points in another online survey, from the RAND Corporation, which has never had him behind but has shown him expanding his advantage in recent days. Mr. Obama also led, but by less than a full percentage point, in a poll for Investors’ Business Daily.

Mr. Romney, however, still held leads in two other tracking polls. The Sunday edition of the Rasmussen Reports tracking poll put him up 2 percentage points, a 1-point gain from Saturday, while he maintained a 2-point lead in the Gallup national tracking poll of likely voters."

The WaPo/ABC News poll could indicate that Obama has rebounded from the first presidential debate.
