Obama's mother was definitely born in the US. If someone were to prove after the election that Obama was actually born in Kenya, and he had won, I suspect Congress would just redefine "natural born" so he would qualify (by making anyone who had one parent born in the US a natural born citizen--the only snag at present is that Obama's mother was too young to meet the terms of the law).
>>>...and Congress passed a law during the Washington administration defining what that meant.

>>>Obama’s mother was definitely born in the US.
She was a minor when she became pregnant and not old enough to pass on citizenship.

They can’t do that unless they amend the constitution.
