I don't know but here are two straws in the wind:

"I trust him. I think he is talking about a new kind of politics. It's courageous. Hillary is slick. Democrats are taking us for granted," - Angels Daws of Harlem.

And Juan Williams:

In a nation where a third of the population is now made up of people of color, Mr. Obama is in the vanguard of a new brand of multi-racial politics. He is asking voters to move with him beyond race and beyond the civil rights movement to a politics of shared values. If black and white voters alike react to Mr. Obama’s values, then he will really have taken the nation into post-racial politics.

Obama himself is counting on Iowa to do the job, even though it has a very small black population. Why? Because one of the biggest obstacles to black support is the widespread sense that a black man can't get elected in America. If a black man can win the Iowa caucuses, they might just begin to change their minds. And if they do, then South Carolina looks much more promising for the Illinois senator. If I were Clinton, relying - again! - on her husband to gain power, I'd be worried.
