Actually David looks like a Negro. Barack, at least in this picture, looks very like an Arab with anomalous hair. Actually Arab would fit with Kenyan/Luo parentage as the Luo(Sr.’s folks) are half or more Arab in descent.
I truly don’t care if Obama resembles him or X or any of them since it doesn’t prove anything. Now, if Obama would get DNA tested along with relatives and others for comparison - but that’s not going to happen.
