Apparently there is. There were numerous articles about the phenomenon early on. 
Actually, in this case you are having to defend what apparently educated black people said...
Definitely. However, it was nonetheless an interesting idea, that black columnists would note that although Obama was Afircan-American, hesimply had no connections to what is considered the black experience, and is therefore not "black". When there is a 
Time article on it, I think that enough people have caught on to it...
Some notables: 
Debra J. Dickerson, 
Sallim Muwakkil, Stanley Crouch, 
And that, of course, ignores Sharpton's and Jackson's comments on him...It's nice to see that the black community isn't monolithlic, but c'mon...
[Just thought 
this was funny, BTW...]
And again, not in this case. You have some very smart, very educated blacks who disagree that Obama should be considered black in the first place. And besides, what about Farrakhan, Malcolm X, and even the NAACP? Does every black person need to be a great example of a person, or can they just be human?
Sorry; just finding it interesting that a white guy says what a lot of blacks have been saying for a while and he's racist and they're okay for stating the basically same opinion...Why should the color of the person's skin matter more than what they are saying?
