I don’t know whom you are addressing-—you would be hard-pressed to find many people on this forum who think Obama has documented anything.
There are quite a few who want to evade the issue but among those of us who have checked it out, SEVERE DOUBT and DISGUST are the most common reactions.
And also quite a few who believe they can demonstrate a birth outside the US and/or non-NBC status due to his Brit subject father and underage mother.
But not many who think 0 is clearly eligible.
ME EITHER! ! ! ! ! !
I can't demonstrate country of origin, but I really think that's irrelevant WRT Obama's putative natural born citizen status. As you note, the evident fact that he had a British-citizen father means that Obama is not a natural born citizen as that term has historically been understood in this country (e.g., as having two American citizen parents). There is also the likelihood (IMHO) that Obama became a citizen of Indonesia when his step-father, Lolo Soetoro, adopted him. So even if he were born on U.S. soil, as a "dual citizen," he would not be considered a natural born citizen, on grounds of potential for divided loyalties.
Obama has hid virtually all his public documents. You can't find out anything about his guy....
And that's not an accident.
