Tribe is being cute by half and his argument holds no water. He’s playing off a manufactured view of what an originalist would supposedly say, and there is no basis for that argument. Cruz was born an of an American citizen and was an American at birth. Unless someone produces some sort of naturalization documents from a later point, there is simply nothing here. It was never an issue, other than for weirdos. Trump had not issue with this, and now suddenly does. Not because the facts changed but because he has decided to take an unfortunate turn in his campaign.
Debating Tribe is not relevant. He’s a guy who’s an advocate for more gun control, more government and more Democrats and his purpose in speaking up is to derail a conservative. That’s all we need to know.
No, what you need is some authority of weight that Cruz meets the intent of the Framers in placing the words “natural born citizen” rather than “born citizen” or “citizen” in Article II of the Constitution. That you do not have as illustrated by refusing to cite any such authority.
