That wording differentiates between citizen and natural born citizen.
Yes, but a "citizen" could be naturalized. A naturalized citizen is a citizen. So that still makes only two categories.
Both senators and representatives can be foreign born and naturalized. BTW here is a list of current and former US politicians who were born in foreign countries.
I don't care how long the list of reps and senator is. We're talking about eligibility for the office of president. Natural born citizen, two citizen parents at time of birth, eliminates foreigners holding that office. Maybe we still get bad presidents (think Carter, here, among others), but hopefully they don't disdain America and her people, as this jerk does.
There is a foreigner currently residing at 1600 Penn'a Ave. Foreign because he is steeped in anti-Americanism (frank lloyd wright, his parents and grandparents, formative years spent in indonesia, moslem identity, this is not an exhaustive list of reasons why he is foreign).
