Earlier quoted context omitted.
It wouldn't have mattered either way because his mother was a US citizen, making him a natural-born citizen even if he were born in outer space.
Obama of course was born in Hawaii and of course he was a US citizen. That said, the law at the time was that if your father wasn’t a citizen, then your mother had to be a citizen AND had to have been living in the US for the previous 5 years. Dumb law IMO but it was the law and was raised by a lot of birthers.
(Not that facts or logic matter to birthers, but anyway)
