Barack Obama has taken the stage. I worried that it would be divisive for Hillary and Bill not to be here tonight -- and they certainly aren't, as Obama just hailed Clinton, but no shot of her face was shown on the jumbo screens. Yet somehow, it feels appropriate, and much less distracting. The past three days at the Pepsi Center felt a lot like the Clinton Show. Tonight it's Obama Time, in Obama's space. --Dana Goldstein
