It could be illigimate birth, or Muslim, or that he was born Barry Dunham, perhaps had his mothers last name on it?
There is some reason that Obama doesn’t want us to see his birth certificate. My guess is that it says his name is Barry Dunham. He went by the name Barry all through high school. Then, perhaps as an act of solidarity with his pan-African brothers, he decided to adopt his father’s given name, Barack.
There’s an untold story. can’t believe Obama spends millions on attorneys to keep that story from being told. A birth certificate is that potentially explosive and damaging?
The Obama/Dunham divorce decree says that they were married at the time of his birth, so he was legitimate in the eyes of the law. And Hawaiian birth certificates (including the long form) don't have a box for "religion."
But so far as I can find out, he went by the name "Barry Obama" in high school -- no "Dunham" and no "Soetero." He did start using the name "Barack" in college, but that could have been his given name anyway: there are certainly plenty of schoolchildren who call themselves by their nicknames rather than what they were born with.
FWIW, maybe somebody in Hawaii can get copies of The Oahuan, the Punahou School yearbook, for the late 1970s.
