The whole reason for the Natural Born Citizen requirement is to avoid foreign influence at the highest level of government. For similar reasons, those in the military, including civil servants and contractors, who work in "Presidential Support Activity", need what is known as a
"Yankee White" clearance. One of the requirements is that the person not have any close relatives; spouse, children, siblings, who are foreign citizens. Obviously, The One, has lots of siblings in Kenya, and at least one in China. That requirement can be waived but "it must be determined that family members are not subject to physical, mental, or other forms of duress by a foreign power and who do not advocate or practice acts of force or violence to prevent others from exercising their rights under the constitution or laws of the United States or any State or subdivision thereof". The problem with that is that O's cousin Odinga, *is* an official, the number 2 IIRC, of the dictatorial Kenyan regime, who used just such duress and physical force to get into that number 2 slot.
IOW, Barry couldn't even qualify to empty the sewage tank on Air Force One.
