Not that kind of logic, GBA.
The term for the logical fallacy you’re referring to is “illicit minor.”
But I’m not stating that the Naturalization Act of 1790 defines Cruz as a natural born citizen.
The point is that it indicates which of several profered original meanings of the Constitution the founders intended.
However, that's not the only claim to citizenship Ted Cruz had at birth, nor was that the only claim on him, since citizenship is a two-way street.
By/At his birth, Canada definitely has a claim on Ted Cruz, too. Maybe a double claim or ? depending on what his father's status might have been and the laws governing marriage and citizenship at that time.
Rubio and Jindal have blemishes on their individual claims to American Citizenship, too. So does obama!
None are natural born citizens, though they are all citizens.
However, obama's situation is the murkiest of them all, since there are so many conflicting claims regarding his birth location and his citizenship inheritance from his father.
Prior to his run for POTUS, obama's claim was his being African born in Kenya.
If true, his situation is similar to Cruz's.
However, Cruz was upfront about his birth location and produced a Canadian birth certificate. Very different from obama.
obama supposedly changed his story to run for POTUS, and only when pushed and shoved did obama produce and release, which Trump takes credit for making happen, what many have said is a fake BC indicating obama's birth in Hawaii.
If the "born in Kenya" to an African citizen father story is true and obama is eligible?
Then pretty much anyone is eligible, including Cruz, but the courts have been made to dodge ruling on the NBC question one way or another.
Personally, I'm glad that Trump has gotten US to look at this issue again.
It's far from settled and VERY unsettling!
