“One cannot be anything else AND be a natural born citizen.”
You are dead right but unfortunately there are members of FR who still think that Ted Cruz is a natural born citizen and many have argued in the past that Obama is a natural born citizen. A lot of people just THINK they know that almost anyone is a natural born citizen of the USA. At 72 I clearly remember when the term natural born was applied to many things other than qualifying for the presidency. I had classmates who were natural born artists, natural born baseball players etc. Now that the term is almost never heard except in reference to the presidency very few people know the actual meaning but that does not stop them from claiming to know. Some actually seem to think that citizen and natural born citizen are the same thing. There are few subjects which seem to bring out more confusion and ignorance.
Technically your statement could be called incorrect even though we both know your meaning. A person can be many other things and still be a natural born citizen of the USA but none of those other things can have anything to do with being a citizen of any other country.
I meant one could not be a citizen or even have the option of being a citizen of another country of any other country and still be a natural born citizen.
Rubio, Haley, Jindal and George P Bush could have chosen to be citizens of their foreign national parent(s) country(s).
Even though they did not act on that option, as far as we know, they are still not eligible, born with divided loyalties.
