Canada may do whatever it wants within Canada. The act of Canada blindly deciding to grant citizenship of its own accord isn’t really relevant to the standing of a foreign (to Canada) citizen outside of Canada. If next Thursday Canada voted to extend its citizenship to you, would you expect to suddenly lose eligibility to become POTUS? I would think not. Your eligibility would depend on actions by you, and the laws of the United States, right?
In the context of your “Anchor babies” argument, Canada decided to make him a sort of anchor baby in their system. If you reject it conceptually for Mexicans coming to the U.S., it would seem consistent to reject it in Cruz’s case as a matter of logic. Is this reasoning wrong?
You reasoning if flawed, yes. But I won’t argue the point with you, because you are not open to reversing your position, and I am not open to reversing mine.
If I had never set foot in the USA I could see how the USA may not have original jurisdiction. I might even suspect that I would have to ask permission to leave via a passport which I was not born with.
I am trying to keep my promise here.
