I had to watch the whole thing. He said what he said, and meant what he said. He is clearly not going to be the next president, but he gained a prize. In fact, I think that his speech thoroughly accomplished what it was intended to; to solidify his true base. That base being the slightly radical and easily deceived; perpetual victims, inventing injustice by blaming the past. In the process, he has garnered the complete attention of the press, thereby increasing his recognition among his base.
The opening, and continuing theme, was about race when it was supposed to be a response about hate. This is an old tactic; redirect and protest loudly. Use as many words as possible, rhyme when you can and blame someone else for their problems. I think Obama wants to be the new Jesse Jackson. The similarities in their speech styles is haunting, for those who remember the old Jackson. He has been getting a bit long in the tooth lately. Even Sharpton isn't so sharp anymore. I think many of the disparate followers of them and of some other "Reverends" will flock to Obama, and we'll be hearing from him for a long time.
All in all, a fairly brilliant move! He will be speaking and getting endowed with wealth for many years, and will likely run again. One redeeming thought is; Hillary is probably happy, but she's toast. Hee hee.
