“If you liked his inane comment, I bet you loved my retort.”
It was essentially meaningless. Yes, people who lived here when the constitution was adopted were natural born and nobody born afterwards gained it that way. They all gained it by being born here.
The constitution only speaks of Natural born citizens, naturalized citizens, aliens, and those living here when the constitution was adopted.
There is no class of citizen that was born here, gained citizenship by birth, but is still not a “natural born”.
Cruz wasn't born here. He was born in Canuckistan, where the only way they can receive citizenship of any kind is via congress, and, that, only a type of naturalization that is instant at birth. His father is not an American citizen, nor was he born here in the US, and is, therefore, unable to receive natural born status.
