Obama has visited Kenya according to his books and according to photos that are on the internet. How did he get an American passport without proof of citizenship? Where do people speculate that his mother gave birth to him? This kind of scrutiny of an internet document is a waste of time, I believe, although it is quite possible that someone has decided not to show the true birth cert of Obama. Perhaps his mother and father were not married, and no father was named.... Possibilities are numerous for reasons to hide the true document.
Having citizenship is not the same thing as being a natural-born American.
What if he was born and named Barry Dunham? (Parents not being married not the issue...the disclosure of the 'white' family name) or perchance, Stanley Ann listed his 'race' (if it was asked for on the birth certificate) as 'caucasian' (yet another embarassment of near Biblical proportion for Team Messiah).
I don't think its the 'local'...I think its who the contents would be 'received' by the masses.
Lowell P. Weicker, Jr. (as despicable an excuse for humanity as has ever sullied the Senate by his presence) was born in Paris while his American citizen parents were there on business. He was a citizen. George Romney (Mitt's father) was born (IIRC) in Mexico and evidence exists that his parents had left Utah for Mexico because they were (though monogamous) angry at the US for forcing monogamy on Utah as a condition of citizenship. Whatever. George Romney was an American citizen by birth to American citizens.
As to those born abroad, one parent's American citizenship will suffice. As to those born in American territory, the parents' citizenship is irrelevant and the child becomes an American citizen by birth. The child in any of thee cases may also have citizenship in other countries. Contrary to popular myth, dual and multiple citizenship is allowed and raher common. Elizabeth Taylor was born in England and has English citizenship. She also, in youth, was naturalized as an American citizen. She converted to Judaism when she married Eddie Fisher and acquired Israeli citizenship. She has that triple citizenship to this day.
