“...if it was faked.” If the certificate was faked, the reasons are likely one or more of of the following:
1. His father, BOH Sr., was married to a woman in Kenya and never divorced her making him a bigamist under US law.
2. His father who left or divorced Obama’s mother never adopted Barry thereby making his name Obama and his autobiography fraudulent and fictitious. (Liar, liar pants on fire.)
3. The original certificate shows his father's race not as “African” but as “Arab” which the senior Obama would likely claim at the time given that he was a Muslim and considered himself descendant of Arabs in Kenya. (A bit tougher to win the hearts and minds when you are not an African American but an Arab American?)

Why would Obama’s father have to adopt him?
