He does? Gee, I didn't know that Ann and Stanley Dunham were black!
If we’re going on looks, there have been photos of the various faces, and 0’s facial structure actually does not resemble the Dunhams. None of them have receding chins, that’s about the extent of the resemblence.
If skin color is the only factor you see in resemblance between people, then any black person looks like any other, and there is no point in having this conversation.
For the rest of us, who perceive body type, bone structure, face shape and configuration, chin formation, and facial expression - the similarities are more than obvious. Obama looks more like the young Stanley Dunham than like any of his putative fathers.
