Concluded
From Rogers v. Bellei
"But it [the first sentence of the Fourteenth Amendment] has not touched the acquisition of citizenship by being born abroad of American parents; and has left that subject to be regulated, as it had always been, by Congress, in the exercise of the power conferred by the Constitution to establish an uniform rule of naturalization."
That’s a great case for this situation.
Again. Regulated by Congree = naturalization process.
NBC means citizen by birth period from day one of our Republic.
Cruz in every discussion confuses deliberately citizen and NBC. He knows he’s not eligible but thinks SCOTUS will punt on the issue.
Rubio is also not a NBC.
It's more about citizenship lacking considerations towards "naturalization" any language to that effect being found from within the dissent, and that consideration (naturalized? or no?) not being among the reasonings included from within majority opinion.
The majority made no mention of concept of naturalization be applied to Bellei in Rogers v Bellei when that concept was otherwise discussed. Instead, what was talked about was his citizenship from birth -- which Bellei did indeed lose -- for reason of not complying with the residency conditions which Congress, the Court found are allowed to require under the Constitution.
Bellei was challenging the constitutionality of the codes (the laws) which were applicable to him. It was decided by the majority that the laws were indeed "constitutional".
