OK, so Mr. Bingham would say that someone like Ted Cruz, who was born in Canada, would be an adopted citizen of the United States. Marco Rubio would be a natural born citizen because he was born in the Republic and both of his parents owed allegiance to the United States only, because they were here under the Cuban refugee statutes and were later naturalized.
However, this conflicts with what Ted Cruz wants, so the Constitution must be bent, but just a little! What harm can come from bending the Constitution just a little?
