No way Obama is half black and half white.
He just doesnt have the appearance.
We could always contact Fredshelm and ask him what his information is.
Yesterday I remarked to a friend of mine that bam is actually darker skinned than most mulattos I have seen. Owing to the fact that Malcom X was very light skinned and F Marshall Davis was fairly light skinned as well, if either one of them had been his father, with a white mother, he would have been much lighter skinned than he is and the black features, lips, hair, would have been less pronounced. It led us to conclude that if bam Sr was NOT his biological father, someone equally as dark skinned would be...which is highly unlikely.
I also considered that perhaps it was a generational fluke that caused the black genes to dominate his features, but it really doesn’t follow since Dunham was about as lily white as you can get.
