George....I think your assumption of my assumption is incorrect...as Mr McGrath would say.

The vote which is open to being questioned, is the black vote.
Not questioned by me of course, but by conservative white Americans.

BTW, I have a very good friend, who is a black from Chicago, she reckons that the expectations of black and "liberal" Americans vastly exceed what can be realistically achieved.
She also thinks that Mr Obama's inability to deliver on these expectations could be a setback to black aspirations...Ake
