I am not so sure Obama knows he is lying, I think he has created these illusions of his father to make it easier to cope on a personal level. Maybe Obama's mother lied to Barack to make it seem like he wasn't son to a wife-beating , polygamist, drunken goat herder and Barack just doesn't know any better. Anyway you look at it Barack Jr. is naive and not realistic.
Read the list again, Barack’s father was not a goat herder. In fact, he was coddled by his government.
