The Supreme Court trumps Black. It was unanimous in exclusively defining natural-born citizens as “all children born in the country of parents who were its citizens.” It has also affirmed in multiple cases that the citizenship of a child naturally follows the status of the father, not the mother. Cruz does not qualify.
I don’t think that the court has so ruled. The fact that Cruz was able through his mother to get a US passport is a fact against you. Furthermore, why would the court even bother with an issue where the only clear-cut decision would be like that of John P. Altgeld, who was born to German parents in Germany? IAC. I think you forget the essentially political purpose of the Constitution. It is an instrument of government, not a statute, and the use of the term “natural-born,” or “native”, which is the word that Justice Storey employed, aimed at a political purpose, which was to debar the election of a foreign prince as chief magistrate, so as to secure the presidency as a republican office. Everyone knows that when they devised the office, everyone had their eye on George Washington —the man who had repudiated any effort to make him a Caesar, a Cromwell, or a king. Europe was full of princelings who might have worn the American crown if it had been available and the best way to keep them where they were was to insist on the homegrown talent in the highest office.
