You can be natural-born without being born in the territory of the U.S. As long as the law says you’re a citizen at birth you’re a natural-born citizen. That should be patently obvious from the meaning of the words in the phrase.
Obviously you are another one of the many around here that believe our constitution is a living document and it means whatever you want it to mean. In 1790 Cruz would not have even been considered a citizen of the USA. Did that get thru? Not even a citizen! Now how you go from not even a citizen to a natural born citizen (NBC) as the founders considered NBC is quite the mental feat.
Cruz is a naturalized citizen. The 1934 Naturalization Act (and follow up legislation) conferred citizenship on Cruz. If a Naturalization Act confers your citizenship you are not a natural born citizen. This is not rocket science. No legislation confers citizenship to a natural born citizen. Here is a question for you. My parents were US citizens I was born in the USA, what law makes me a citizen?
The son of a Cuban, born in Canada to an American mothers is not a natural born citizen if you go by original intent. Not even close.
So any of the 900+ Saudi’s born in Saudi Arabia, practicing Sharia to subjugate women, with American mothers and Saudi fathers are all Natural Born Citizens of the USA? Oh really!!
