Theory?.... Wuz he wuz, or wuz he not, "adopted" by his Indonesian Step Father?
Well wuz he?
The purported Indonesian school record describes the family relationship as parent Lolo Soetoro, stepfather and the student Barry Soetoro as stepson. The implication is that Indonesia is likely to have mandated by law that the stepson, Barry Soetoro, become a citizen of Indonesia and a Muslim for the school record to exist at the time in which the record was created. The validity of the school record cannot be legally proven without an order from a court of law having lawful jurisdiction to grant right of discovery, and/or Obama’s granting permission to obtain copies of his personal records. So far, Obama has used legal assistance to obstruct all efforts to obtain the required permissions or court orders required to obtain legal discovery of any evidence which may be pertinent to such a case.
Consequently, the school record and the legal divorce papers are the presently available records which document the stepfather and stepson relationship. The papers documenting a legal adoption are presently unavailable, and they may not exist if the adoption was not formalized in legal paperwork.
Doesn't matter. A child either is a natural born citizen at birth or he is not. A parent's action, including adoption, cannot change that status.
Of course it requires birth in country, or in it's armies or diplomatic corps, and two citizen parents. We know, from his own writing (or Bill Ayers?) and the COLB, if it's legit, that he fails on the second test. He may fail on the first as well.
Well wuz he?
Without seeing his long form birth certificate, no way to know. Even then the form might only show a name change to "Obama", without saying what it was changed from.
However there is some evidence, in the form of the divorce papers from his mother's second marriage to Sotero, which list a child over 18 that needs educational support, as well as his half sister Maya. That implies that he was adopted, but does not prove it. The same is true of the Indonesian school registration which shows his name as Sotero and his religion as "Muslim". But it's equally possible that his stepfather lied on that form, because otherwise he'd not have been able to attend school in Indonesia (didn't have to be Muslim, IIRC, but you did have to be an Indonesian citizen).
