It's all explained.
Unfortuately in the very first sentances it shows it’s own BS
“Is Barack Obama constitutionally eligible for the “presidency?”
“We don’t know.”
We do know. He is not because he lacks parents who were both U.S. Citizens at the time of his birth.
Any male other than Obama Sr. who claims to be Obummer’s father will have to sue in court to establish legal paternity. But any other possible male is dead and can’t sue, so that is that.
The records that do exist will not support any other conclusion. Under the law you may be “fathered” by another and still be the son of the man who accepted you as his son.
biology doesn’t always equate legality.
thus, Obummer is not a natural born citizen
The only open question is, is he a citizen? and if so by what means?
