You are right, there is only hearsay. From Obama's paternal grandmother who says she was there when he was born in Kenya and a affidavit from some preacher who says he was there during her interview.
Then that Kenya person, Ogaego or something like that who says Obama birthplace in Kenya is now and always has been a shrine of some sort. It made it sound like it was Obama's grandmothers home maybe.
As far as the divorce saying Ann was in Hawaii when she married and when she divorced, Washington college says she was there in school around Obama's birth.
From the story I have read, (one of many *wink*) is Stanley Ann went to visit Obama Sr's family in Kenya before Obama was born. Then was not allowed to take a flight home because of the delivery date being too close.
So, then she would fly back after the birth and file for a late birth certificate in Hawaii that was allowed at that time. That type of BC is not natural born citizenship.
If there is any truth to Malcolm X story at all, Stanley Ann could also have flown back and based on her word alone been able to get the same late birth certificate and not be the actual mother.
What evidence do you have that the State of Hawaii permitted out of state or our of country births to be registered in order to obtain a BC in Hawaii?
