Not to me.
Can there be doubts, argument in other configurations like we're having now?
Sure.
What do you think the Founding Fathers meant with that in mind?
They didn't say only born here, only born to 2 citizen parents, so I don't think that's the only way to be a NBC.
They used the term widely known at the time from Vattel’s writings, NATURAL BORN CITIZEN!What you think doesn’t matter. What the Founders thought, does.
