Please share your analysis. I’ve been thinking about that speech too. It was “a speech for the ages.”
Obama is different because:
1) He does need to apologize for his association with a purveyor of race hatred
2) He and his wife don't especially feel proud of this country
3) By using Alinksy ju-jitsu and turning the race issue back against whitey, he is not transcending racial politics but merely using it to his advantage -- and I don't think that will work in this situation.
