Since you conveniently ignore what doesn't agree with your take on reality, do NOT, I repeat just in case you missed it, DO NOT look up the definition of dual citizenship.
Better yet, why dont you go ahead and give us all a legal reference to dual citizenship being a qualification for Presidential eligibility. Go ahead. Well wait.
So, here, learn a little and learn to do you own research instead of just repeating other statements from the Internet and sounding stupid:
United States Code, Title 8, Section 1401:
The following shall be nationals and citizens of the United States at birth:
(a) a person born in the United States, and subject to the jurisdiction thereof;
"Natural Born" only requires common sense in that a person born as a citizen and does not require any additional acts to become a citizen is a natural born citizen.
So, go find Title 8 Section 1401 and read the rest of it. Learn a little. I am tired of you sanctimonious pinheads trying to talk down to everyone when you dont know squat.
