She was born in the U.S. to parents who were both here as LEGAL immigrants and wholly subject to the jurisdiction of the U.S. She was a U.S. citizen at birth by virtue of her birth. She is not a naturalized citizen. No court is ever going to hold that she is not a natural born citizen since she is undeniably more of a citizen than Obama ever was.
Spin this to your hearts content. Neither of her parents are US citizens....
So your interpretation of “natural born citizen” requires that your parents also be citizens (and not merely legal residents) at the time of your birth. Do they also have to be natural born citizens? If so, how many generations do you have to go back?
Under the 14th Amendment, she was born a citizen. That would not necessarily be the case if her parents had been illegal aliens and, therefore, “not subject to the jurisdiction” of the U.S. That is not an issue because her parents were both here legally when she was born.
