In American law and in the common law, citizenship is determined by soil before blood and that's the dirty little secret that nobody wants to talk about.

Using this logic, then some guy from Uganda who happened to be born in the U.S. 45 years ago while his parents were here on a six-month work assignment would be eligible to be President, but Ted Cruz would not.

The basic premise here about "soil over blood" doesn't make any sense at all.

The argument could be made that he was eligible. He would have to move back here and be a resident for 14 years before at the very least. Regardless, United States v. Wong Kim Ark is pretty clear on the subject: All persons born in the allegiance of the King are natural-born subjects, and all persons born in the allegiance of the United States are natural-born citizens and Allegiance is nothing more than the tie or duty of obedience of a subject to the sovereign under whose protection he is, and allegiance by birth is that which arises from being born within the dominions and under the protection of a particular sovereign.

It makes sense. I'll explain in a moment. But the question is, what does the constitution say? Reference to SCOTUS precedent is useful to figure what SCOTUS would say, maybe they got it wrong some time ago. Both the constitution and 100% of the SCOTUS precedent that touch on this or similar question of citizenship reach the same conclusion. If applied to Cruz, he is naturalized.

If jus sanguinas is superior to jus soli, over generations, nations will disperse. National identity will be eroded until, at some point, it is only an interesting artifact of one's blood line. All nations are eventually spread over all the earth.
