I don't think he KNOWS who his father is. I don't think his MOTHER knew either.He was raised by his white mother and two white grandparents but he wrote no books about them. His father simply took off when he was around 2 and obama never saw him again except for a couple months when he was 10. On top of that BO senior was a wife-beater and a serial drunk driver who once killed a man by while DUI!!!
A truly evil rotten person but obama idolized him because he was black. More proof that Obama hates all white people.
Frankly, I don't believe for one second, that BO Senior is the younger's father. I truly believe that Frank Marshall Davis is his old man.
However, to make the narrative "fit", it would be necessary to keep up the ruse....Hell, look at the photos. Barack Obama is no more BOs father that Ronald Reagan is.
