Rubio is a natural born citizen because he was born here.
What you speak of doesn’t matter at all.
Your interpretation of what the constitution may or may not say doesn’t matter at all. The only thing that matters is the precedent that exists right now, and that precedent is that if he has a peice of paper forged or unforged that says he was born here, then he is eligible.
That being said, I have no intention of supporting Rubio at all.
Thus the problem with the U.S.
