Consider this hypothetical. A current citizen of the US was born in the US. Both parents are US Citizens. The paternal Grandfather was an immigrant and naturalized US Citizen. However under the law of the country of his origin, the current person is also a citizen of that country. Is there an argument the current person is not eligible to serve as President? If so, having reached a signficant age of seniority, is such an argument enhanced by the fact that the current person also holds a Passport from the country of his grandfather's origin? No, some other country's law does not matter. What matters is the citizenship status, as recognized by the US, of the parent or parents, depending on wether you are talking about the "Two parent" or "patrilinal" rule. The fact that both parents of the current person were citizens, even if one was a dual citizen, and that the current person was born in the US, makes that person a natural born citizen. I think that's right. You might add, the current person was never subject to the sovereignty of the grandfather's county and thus even though he was a citizen there at birth (a common situation under Euro law), that's irrelevant. Although if he goes there and subjects himself to the sovereignty, maybe the answer is different?
In your view, can a person ever lose his status as "natural born"? If so how? Under what theory if he was born in the USA?
Come on, David. Evene you would agree that if a person obtained dual citizenship after being natural born, and subsequently exercised the citizenship of the other nationality, that would be a prima facia rejection of natural born status under the apparent definition held in common by the writers of the Constitution.
