Jumping back in a little late here thanks for the redirect to your again very thoughtful comment, but I think what you’re missing is that Cruz is a naturalized citizen. How do we know? Because in order to determine that he is a citizen we have to look at a naturalization statute. Jus soli (born on U.S. soil) and jus sanguinis (born to two U.S. citizens) are a given: all of those kids have been considered citizens at birth for centuries if not longer by generally accepted principles of common law without reference to any statute. But when you get to born abroad with divided loyalties, that’s always been subject to statutes that granted citizenship in some cases, not in others, in some times, and not in other times. That’s a naturalized citizen, citizen by statute.
Thanks for your reply and see this post:

And see also that Chester Arthur’s father was an immigrant and didn’t become a citizen before his birth:
“Arthur was born in Vermont to a Vermont-born mother and a father from Ireland, who was naturalized as a U.S. citizen in 1843, 14 years after Chester was born. Despite the fact that his parents took up residence in the United States somewhere between 1822 and 1824, Arthur additionally began to claim between 1870 and 1880[82] that he had been born in 1830, rather than in 1829, which only caused minor confusion and was even used in several publications.[83]”
