What he may be saying (and I’m chiming in, he can correct what he means if need be) that 0bama has, by presenting the COLB plus his two “autobiographies”, committed himself legally and otherwise to having 0bama Sr as his father. He’s boxed himself in, so to speak. So if 0bama Sr is not his father, he’d have to admit that the COLB is a total forgery and lie plus his books are lies.
And now, since all of 0bama’s relatives except putative Kenyan ones and a great uncle or so are all dead and gone, no one is around to say “yea” or “nay”. His mother could say who his father is without doubt (unless she had a bunch of men around), and 0bama Sr could at least say whether he had relations with Stanley Ann or not. But, they could both lie. So, how to tell for sure?
0bama Sr’s other son Mark with the African last name could give a DNA sample and 0bama could give one and they could be matched to see if they are actually related by blood.
But I don’t see that happening in the near future!
Also, even if 0bama Sr is the actually sperm donor, that doesn’t mean anything or everything else on the COLB is factual, since it’s pretty well determined that the thing is forged.
Thanks — I couldn’t have said it better.
