I doubt very much if you have the slightest idea as to the intent of the Framers.
I have taken my perspective on this matter (and I have been studying it for over a decade) from Emmerich Vattell, who I know for a fact was held in high esteem by the Framers and whose works were consulted frequently:
“I say, that, in order to be of the country, it is necessary that a person be born of a father who is a citizen; for, if he is born there of a foreigner, it will be only the place of his birth, and not his country.”
So, Ted Cruz was Bron in Canada, but according to Vattell, Canada was “not his country” - it was merely the place of his birth.
In point of fact, if you accept the notion of natural citizenship at all, you have to accept the fact that every child on born has a natural citizenship inherited from his parents, or at least from one of them, and in the case of Ted Cruz, that natural citizenship and allegiance is to the United States of America.
Cruz has a Canadian birth certificate... There is no way Cruz will ever be a ‘natural born’ US citizen... I am reminded of Christ speaking to those that sit in Moses seat.. Moses was the official law giver. Look what the legal sages have done to our not your US Constitution....
Born ABROAD to a CUBAN father, mother's citizenship status MURKY at the time of his birth. Too many problems with Ted. He'd be better off running in Canada.
