Barack H. Obama II’s legal father is a citizen of Kenya, Barack H. Obama.
Who his bio dad may be is of NO LEGAL import.
If Barry's LFBC was forged, we have no “legal father” in evidence.
Even if a 1961 HI or Kenyan BC were to be found and certified showing BHO Sr. as the claimed father, that would NOT make Barry “legally legitimate” if BHO Sr’s marriage was bigamous due to his marriage to Kezia being lawful under the Kenya Marriage Act.
BHO Sr. Being the “legal father” of Barry does NOT make Barry a UK subject dual citizen under the 1948 BNA if Barry is a legal bastard due to his father's bigamy, if proved.
As yourself whether Barry would throw his father under the bus by declaring himself to be a legal bastard to claim legal unitary US citizenship from his legally single mom if it would save his presidency and tip SCOTUS in his favor.
BHO Sr. has already been revealed to have been declared to be suspected sexual predator and bigamist by the US INS...a revelation suspiciously timed to give legal cover to Barry, if necessary, should legal claims get serious that he is not NBC due to his own claim to being a “claimed” US subject at birth.
Barry can un-claim that claim to have been a UK subject at birth at any time and just say “I had no idea I was born a legal bastard even if BHO Sr. was my legal father! It turns out that under the 1948 BNA I am was NOT a UK subject at birth and only a US citizen through my mother.”
It is crucial that Barry's claim to be an NBC be challenged given his claim that he was a UK subject at birth, but IMO, Barry has had an escape available by admitting he was a bastard all along, and he knows it.
Not being born in HI and actually being born in Kenya would be a disqualifying NBC fact that Barry can't defeat, if proved. So IMO where he is born remains crucial and his NBC status is squishy.
