WaPo/ABC: Romney, Obama locked in favorability ratings

A new Washington Post/ABC poll shows Barack Obama with a 49%/48% favorability rating among registered voters, while Mitt Romney scores a 44%-44% rating -- an effective tie.

Since April, Obama has fallen by 10%, while Romney has jumped by 8%.

Even more good news for Mitt?

He's gained 13% among women in just one month, while Obama has fallen 7% with women. That being said, the president still retains a better favorable rating with the demo, 51%-40%.
