What's with those 10% of black people who don't support Barack Obama?

Cinque Henderson explains:

I disliked Obama almost instantly. I never believed the central premises of his autobiography or his campaign. He is fueled by precisely the same brand of personal ambition as Bill Clinton.

And he's pretty irked by the way white people like Obama:

So much of the educated white people's love for Barack depends on educated white people's complete ignorance of and distance from the rest of us. Barack is the black person they want the rest of us to be — half-white and loving, or "racially transcendent," as the press loves to call him.

Well, that rings true, but is it really so terrible? Why doesn't it bother the 90% of black who do support Obama? I'm sure they notice, and I'm guessing they think we're a little pathetic, but decent enough and reasonably tolerable.
