I am white and probably have no right to comment here, but since Obama is the whitest dude to run as a black, since Bill Clinton was declared to be America's first Black President, I feel everyone has a right and obligation to speak.
If a candidate is white-in all likelyhood, he is not black.
No way does Obama look white or anything else but black. If you saw him on the street without knowing who he is or anything about his background, you would see him as a black guy. I see black people (with two black parents, not biracial) that look whiter than him everyday, including members of my family.
You are very good sir. I salute you.
