A strikingly expansive speech, a reminder of what Obama can deliver when he wants to. My sense is that he is holding back, or rather has been holding back. He is very, very careful not to get too angry as a black candidate. Perhaps too careful for his core message: real change. What he needs to do is find a way to explain how serious he is about change while explaining that he alone can overcome the boomer polarization that has prevented it. And that's true on the race issue as well. Yesterday, the message got sharper. Money quote @ Andrew Sullivan
