I think alot of that is because White people see him as a black man and dont acknowledge his white side..they could claim him too, but they choose not to...stupid IMO....Black people always claim their mixed people for the most part...I am also willing to bet that Obama's experience with racism, etc. in America would not mirror a white person's...he is a man of color and that is the first thing people see...him being white never crosses people's mind nor do they accept it(some)...Him being part black/white wasnt a problem for black people, it was a problem with white people....
