Barry looks a lot more Kenyan than Indonesian. If true, this would mean his mother was rolling in the hay with Soetero 10 years earlier than previously thought or, she had young Husseins name changed to Soetoro and then got a whole round of updated official documents.
At some point Hussein Soetoro's name had to have been changed to Hussein Osama.
Soetero is his adopted name. When you are adopted, they issue you a new birth certificate with your new name.
He later changed his name to Obama in honor of his birth dad.
No one knows (so far) what is on his original birth certificate, it would have been sealed when he was adopted.
When a child is adopted, vital records changes the birth record, once they get the adoption decree. The very first BC may still say Obama, but it likely is sealed or destroyed.
There are two interesting things here. The Indonesian adoption must have been registered in Hawaii to make this change, and of course, Hussein lied about all this.
