We've always had traitors, and always will.
I don't think Snowden is a traitor, though.
I wouldn’t trust ex President of Egypt Morsi’s two sons who were born in the USA as Muslims to be POTUSA.
There are a LOT of people I wouldn't trust to be POTUSA, including the current occupant of the office.
Hillary Clinton? Would you trust Hillary Clinton? How about John Kerry? John Edwards? Chuck Schumer? Nancy Pelosi? Dianne Feinstein? John McCain? John Boehner?
Some would make such possible only because of being born in the USA. I believe the Founders were aware of the possibility and dangers of family and other influences. Of course they did not account for 2plus generation actions
There's no record that they discussed the natural born citizen requirement outside of the committee.
I don't think they tried to restrictively cover everything. They were counting on us not to mess things up too badly.
They DELIBERATELY, and with MALICE AFORETHOUGHT restricted the office of the Presidency to only those who could demonstrate the strictest qualifications for citizenship.
And every since then, Jeff and co have sought to weaken the strict standard and replace it with a NOTHING standard. Jeff even convinces himself that it was always their intention to have a standard which doesn't accomplish their goal of keeping foreign influence out of the Presidency.
Eat your Anchor Baby soup Jeff.
But, have you considered:
Isn't it possible that the Constitutional Convention's final Committee of Style agreed upon a specific definition for the "natural born citizen" term and intended that the specific definition be expressly stated in the text of the Constitution?
Isn't it also possible that some East African mole with great foresight somehow induced Jacob Shallus to omit the specific definition from the formal text and that nobody else noticed?
Supporting Evidence: Kenya is in East Africa!
