He's not the deferent Democrat of the past, swinging back at Clinton with gusto. Ambers has the goods. This quote about meeting the leaders of enemy regimes struck me as an effective one both with the Democratic base and the Bush-phobic center:

"The notion that I was somehow going to be inviting them over for tea next week without having initial envoys meet is ridiculous. But the general principle is one that I think Senator Clinton is wrong on, and that is if we are laying out preconditions that prevent us from speaking frankly to these folks, then we are continuing with Bush-Cheney policies."

If this is a change election, then Obama is presenting himself as the most authentic kind of change. And he's right.
