At least Obama himself is the exact opposite of a political dynasty or royalty (well, at least about as close to it as anyone can be and still be elected President realistically).
He was groomed by chief of staff to Tom Daschle, who was one of the top players in the Senate, from his first day. He might not be political dynasty, but Al is right in that he doesn't match in his socio-economic status with any disadvantaged group, minority or not. He is a Harvard-educated, Hyde Park-supported candidate who was always sponsored by someone higher than him to feed his large ambitions.
