Sufficient

Though I agree that Obama's speech begs more questions than it answers, I doubt most people are going to ask the questions that the speech begs. The simple fact is that the man has the gift of rhetoric. His speech was patronizing, and insulting, and ironic, and... enough. It was enough to quell the riots. It was enough to stop the negative news cycles. And it was enough, I suspect, to satisfy the average voter. Even Mrs. Discipulus (no bleeding heart, she) called the speech "very good" and opined that Obama "got himself out of it."

Alas, I think she is correct.
