What it means is that I am more than satisfied that Ted Cruz is a Natural Born citizen and that if he is determined to be ineligible after he is elected, then Vice President Sarah Palin can take over the reins and appoint Ted Cruz to be Chief Justice of the Supreme Court.
Ted Cruz was born in Calgary, Alberta, Canada, December 22, 1970, to a US citizen mother and a Cuban citizen father.
Relevant law in December 1970 is Pub. L. 82-414 § 301(a)(7) (66 Stat. 163, 236)
The way I see it, Cruz was automatically a citizen when he was born. That was the law. Therefore, the law says he's eligible to be president.
Any high-falutin' discussion of the original meaning of "natural born citizen" is irrelevant in the face of Art I, Sect 8, end of the section that reads: "To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof."
To decide who needed to be naturalized, the Congress had to decide who was automatically a citizen and without need of being naturalized.
According to the law, Cruz was born without any need to be naturalized.
