This is definitely interesting, in an interview he had with the Rocky Mountain News, Ralph Nader (the guy widely believed to have cost Al Gore the Presidency in 2000) had this to say about Barack Obama:
Asked if he thinks Obama is trying to “talk white,” Nader said, “of course….The number one thing that a black American politician aspiring to the presidency should be is to candidly describe the plight of the poor, especially in the inner cities and the rural areas, and have a very detailed platform about how the poor is going to be defended by the law, is going to be protected by the law, and is going to be liberated by the law,” Nader said. “Haven’t heard a thing.”
Nader also says Obama wants to show he’s not “another politically threatening African-American politician. He wants to appeal to white guilt. You appeal to white guilt not by coming on as black is beautiful, black is powerful. Basically he’s coming on as someone who is not going to threaten the white power structure, whether it’s corporate or whether it’s simply oligarchic. And they love it. Whites just eat it up.”
The sad reality is that as a bi-racial American myself (black father and a white mother, lest I get accused of being racist ), I can’t help but agree with Ralph Nader.
In fact, when Obama went from being a homeboy with a part in the middle of his hair, to Mr. Non-Threathening Negro, this Ice Cube video came to mind:

Exit Question: Do you think Obama is trying to pass himself off as white?
