I am not talking about Obama, who is half white, but his father, who looks very black based on every picture I have seen. That blog's contention is that Obama has only 1/16 Sub-Saharan black or Negroid DNA, thus his father has 1/8 Sub-Saharan black DNA with the remainder being "Arab" or Caucazoid. Having seen his picture, I really doubt that his the case.
The picture I think we are both referring to is here, just below Obama's picture:

That said, it would be nice if the blogger would make his research available, instead of just citing it:
Need proof? Research the Kenyan records for yourself. You will find that his father was officially classified as "Arab African" by the Kenyan government.
As Mr. Lamb says, if Obama is not Negro, and is actually minority Arab-African, and his ancestors were Arab slave traders, then his whole persona is called into question, and his identity with Blacks will be seen as a cynical ploy, with his identity as composite as the characters in his books.
