The Washington Post article that Dave mentioned below follows a similar piece in the Politico yesterday in demonstrating that black support for Obama's presidential run, far from being a given, may be tepid at best. The Post cites a poll showing that black Democrats prefer Hillary Clinton over Obama by a 3:1 margin, which compares to her 2:1 margin among white Democrats. Al Sharpton, who is still mulling another presidential run, has lamented that none of the Democratic candidates are representing an "urban agenda," and, in what was interpreted as a swipe at Obama, he said, "Right now we're hearing a lot of media razzle-dazzle. I'm not hearing a lot of meat, or a lot of content. I think when the meat hits the fire, we'll find out if it's just fat or if there's some real meat there."
This could actually be a good thing for Obama, especially in the general election. The only way race will really hinder Obama's ambitions is if he's perceived as the "black" candidate rather than a mainstream candidate for all Americans. So, the more distance there is between Obama and Al Sharpton, the better it will be for Obama's long-term goals.
