Iv'e been watching this with interest. Many of the black leaders ie., Jackson, Sharpton et.al. have been very luke warm to Obama. Jonah Goldberg has an interesting anaylsis:
...I think the narrative about America being too racist for black politicians to succeed is little more than a chestnut at this point. White Americans desperately want black Americans to succeed. This goes for much of the Republican Party as well. Colin Powell, Clarence Thomas, Condoleeza Rice and now Michael Steele have enormous fan bases out there (though Powell's reputation took a beating from his troubles in the Administration). What makes a hash of all this is precisely the attitude on display from some of the people quoted in that Washington Post piece. The black left — and, let's be honest, a big chunk of the black base — thinks that it gets to define who is black by applying an ideological litmus test. Black conservatives "don't count" as blacks according the Sharptons and Jacksons. The result is that white conservatives or Republicans who actually support black conservatives or Republicans are still "racist" because they don't support "real" blacks. In effect, conservatives are racist if they don't support liberal and leftwing black people. Link.
