Is Obama's Bitter Push-Back Working?

Some evidence that this issue could actually help Obama: check out this poll of respondents to the bitter flap before and after they watch Obama's own self-defense. He's the first Democrat I've seen in a long time who doesn't respond to this kind of attack with a defensive crouch. Because he's confident that the underlying facts and arguments will help him make his case. The critical issue for the fall will be how Independents respond to classic Rove-Clinton tactics like this. So far, they're not biting as predicted.

My advice for Obama: seize this some more.
