And here's the link to Kausfiles on that topic, which discusses this essay by Debra Dickerson that asserts that Barack Obama isn't (the right kind of) black. Bob Wright and I talked about the same subject in a segment of Bloggingheads last week, which was based on this blog post of mine, talking about this news article about black leaders not (yet?) supporting Obama.
ADDED: WaPo has a big story on the general subject today:
The question of how Obama chooses to define and approach race looms large as he moves closer to formally launching his campaign next month....
Melissa V. Harris-Lacewell, a Princeton University professor who has followed Obama's political ascent, said that he may be forced to choose: "You can be elected president as a black person only if you signal at some level that you are independent from black people" -- a move she said would be "guaranteed" to make black people angry. "He is going to have to figure out whether there is a way not to alienate and anger a black base that almost by definition is going to be disappointed," she said.
