Phil Valentine is a nut with all kinds of theories about 911 and Bush Nazi ancestry connections. He may have a point about President Obama not being of Luo ancestry. It itself, though, that doesn't make Malcolm X the most likely candidate for his father.
But about the chin cleft. Maybe somebody understands genetics. I don't. If a cleft chin is a dominant trait or gene, wouldn't the son of a man with a chin cleft be very likely to have one himself? There may be a variety of genes and other factors involved, but doesn't Barack's lack of a cleft in his chin make him less likely to be Malcolm X's son?
MX had six daughters, none of them appear to have a chin cleft.
