The questions should focus on his relationship with Lolo Soetoro.
Was he adopted and did he get Indonesian citizenship at any point. Indonesia did not allow dual citizenship. Did Barry Soetoro ever lose his American citizenship for any reason, even though no fault of his own.
Personally, I think it’s unlikely that anything will ever turn up, but as you said, there is something that BHO doesn’t want the American people to see.
Doesn't matter what Indonesia allowed or did not. IF he was a US Citizen, which he likely was, the was still a citizen, under US law, after the adoption and regardless of what Indonesia thought. A parent, natural or adoptive, cannot renounce the US Citizenship of a child.
But that's not really important, the real question is, was he a natural born citizen, since that is the Constitutional requirement.
One of the simplest things he doesn’t want to reveal is , to me most likely, that his birth is out of wedlock and he has been lying all his life about who his father is and needs to keep that up.
After that, is his school records. Why the demands for Bush’s dental records from the national guard but no outcry for Obama’s records of any kinds from the media?
