You are absolutely incorrect.
Whenever I see a poster be so incorrect about something so basic in British law- it calls into question every other thing they have said about Obama and NBC.
IF Obama was born a bastard in the US (and he was according to the facts that are presented) he could not be a British citizen. That is a FACT as per the law of Britain at the time of his birth. There are no laws on the books that I have found that would retroactively and automatically have made him a citizen.
He could have APPLIED for citizenship and asked for a ruling based on later laws and special dispensation and he MIGHT have been approved - or he might not have been.
Obama may have been a bastard child according to United States law. However, the United Kingdom accepted polygamy claims in Kenya and its citizens as it was typical of its colonial rule to accept localized culture.
Even today, Polygamy in Kenya is legal. Your argument fails to take into account that U.K. citizenship is separate from U.S. citizenship.
Sorry, Mr. Obama always was, and still is a citizen of the United Kingdom.
