Because she wasn’t in HI then and the baby wasn’t hers.
What is the evidence that Stanley Ann wasn’t in HI in 1960? The University of Hawaii records her as a student in 1960. Polk’s Directory lists her as living in the house her parents co-rented with the Pratts:
“In a separate [Polk] listing, Ann S. Obama, Obama’s mother, is identified as a student living at the 6085 Kalanianaole Highway address”
(Link below.)
6085 Kalanianaole Highway is the house that Stanley and Madelyn Dunham shared with the Pratts. Not only does Polk list it as Stanley Ann’s home address, Cindy, the Pratt’s daughter, confirmed that SA lived there. Cindy described to David Maraniss the ‘makeshift room’ [read: hallway] SA occupied when she resided at 6085 Kalanianaole Highway.
They aren’t all three lying. Polk conducted door to door interviews. They wouldn’t have listed Stanley Ann as a resident at 6085 Kalanianaole Highway without evidence.
There’s no reason to accuse Cindy Pratt of lying either. Although she confirmed that SA had lived at the 6085 Kalanianaole Highway address, she flat out denied SA was living there during her pregnancy. If Cindy were lying, then why would she destroy Obama’s Born-in-HI myth? Because that’s what she does. In confirming no pregnant SA at the address listed on the BC and the birth announcements, and confirming that SA neither left that address to go to the hospital nor returned to that address with a baby, Cindy nuked Obama’s HI birth story.
There was also a college friend, Kiri Tith, who places Stanley Ann in Honolulu in 1960. He’s the one who also knew Obama Sr, and who says he had no idea that Sr and SA even knew each other, much less had a relationship. How could you accuse him of lying? If he were lying, why wouldn’t he claim he knew SA and Sr were seeing each other? That would have helped Obama. As it is, Tith, like Cindy Pratt, undermined Obama’s story.
At some point the, ‘they’re all lying,’ claim wears too thin. It simply makes no sense.
