Why is a student, in love with a Kenyan man and future husband, letting some pervert take nude photos??
Duh! I don't think she even KNEW BO Sr. at the time. I think that her daddy paid BO Sr. to take responsibility in order to protect his good buddy, FMD. FMD was being watched closely by the FBI. He would have been arrested if word of this liaison had leaked out.
BO Sr always needed cash. There is no record that they married. They never lived together, There is no memory of them "going" together, despite Neil Abercrombie.
One common theory is that the Kenyan Student love affair was a cover story for the fact that Daddy's best friend Frank was diddling Daddy's little girl and got her pregnant. When the baby came out there would be no denying that it's father was a black man. They ONLY way to get Frank out of trouble is to come up with someone else to claim paternity. They look around, and see Barack, and make a deal with him. For a little money and some side benefits courtesy of Stanley Ann, He can pretend to be the daddy. Of course he doesn't really give a rat's @ss about her or the kid, except where he can leverage them for his own benefit such as his INS deportation stuff.
All of this fits with the observable facts.
