The Dominion of Canada doesn’t get to decide who is, or is not a natural born US citizen.
Canadian law is irrelevant to this discussion.
A citizen at birth is a natural born citizen and has never needed to be naturalized.
According to U.S.C Title 8 Section 1101 - Definitions (https://www.law.cornell.edu/uscode/text/8/1101) subsection A part (23), the term “naturalization” ONLY occurs after being born. Thus a person who, by the circumstances of their birth is a citizen, and never needs to be naturalized.
It is organic to a nation state to define it’s boundaries as well as it’s citizens. Every nation does this. The US Constitution vests the authority to determine the rules of naturalization - which includes all rules, with Congress. This is specifically enumerated in Article I Section 8.
Thus Congress is vested with the authority to determine who are aliens and need to be naturalized in order to be a citizen. It also is vested with the authority to determine who is a citizen. Some are citizens via naturalization, some are citizens AT BIRTH (the at birth is important). Congress has addressed this issue by determining who is a citizen at birth. The current state of the law is addressed in Title 8 section 1401 - Citizens at birth (https://www.law.cornell.edu/uscode/text/8/1401).
Under subsection A of that code, all who are born on US soil are US Citizens at birth and having never been naturalized are therefore natural born citizens
Under subsection G of that code (even the prior version), all who are born to at least one US citizen parent, as long as that parent has met the time requirements for residence inside the US, is also a citizen at birth. And like subsection A above, have never been naturalized and are therefore natural born citizens.
Maybe the Founding Fathers REFUSED to define Natural Born Citizen for a reason. Maybe a POTUS's policies are infinitely more important than the unsubstantiated views of those who simply cannot get over Obozo getting away with violating what they imagine or fantasize the constitution to mean. Rubio's parents were not known to be citizens when he was born. Maybe Bobby Jindal's parents likewise. Does anyone know who Ben Carson's dad was? What if his mother does not know? Trump's mother was born in Scotland as a British citizen apparently and may not have naturalized before he was born, in which case TRUMP!!! was also a Brit citizen, etc., etc., etc. Can we concentrate on beating the Demonrats now and electing a candidate best suited to revive the Republic? Haven't the Demonrats given us enough REAL ISSUES to beat them with?
If TRUMP cannot see himself nominated without disqualifying the field, maybe he should go back to his lifelong profession of bribing leftist NY and Chicago and Atlantic City politicians for favors rendered to his businesses?
Aw, did you write your own Constitution and make up that provision all by your little self? So cute. But go back to playing with Duplo blocks. You're not ready for the 1st grade level yet.
... No, cruz was a Canadian at birth ...
Just as John McCain was a Panamanian at birth.
Get over it already.
