>>That position was repudiated by the Supreme Court in the Ark decision.<<
The answer lies not in the word “citizen” but the difference between “natural born” and “naturalized”
Can you quote the Ark case where it says he is a “Natural born” citizen?
A distinction that was not raised in the Collins article that Donofrio is trumpeting. According to Collins, if your father was not a U.S. citizen then you don't qualify for any kind of citizenship, natural-born or otherwise. It was that position that the Ark case clearly repudiated.
But the Ark decision also ruled that children born in the U.S. are citizens at birth, a status clearly distinct from naturalized citizen. Since the Constitution identifies only two forms of citizenship then citizen by birth, citizen at birth, and natural-born citizen are all synonymous.
