You’re incorrect.

“.......Birthers have been asserting that, since Rafael Cruz did not become an American citizen until 2005, and while he was in Canada with his wife, during which time Ted was born, he became an Canadian citizen. This, in the Birthers’ view, disqualifies Ted from this Presidency, as “the Founders” never would have intended someone like him becoming President
But look closer at the bolder portion. It never says that the father has to be a citizen of the United States at the time the child is born. All it says is that citizenship “shall not descend to persons whose fathers have never been resident in the United States.” It is indisputable that Rafael Cruz was in the United States for a period of time prior to both Ted’s birth and his marriage to native born American citizen Eleanor Elizabeth Darragh Wilson in 1969. He fled Cuba in 1957 at the age of 18, arriving in Texas. There, he attended the University of Texas, graduating with a degree in mathematics in 1961. He even married his first wife there, Julia Ann Garza, in 1959. They later divorced, but not before he had two daughters with her. He was also granted political asylum in 1961 upon his graduation from UT.”..................
Did Canada have birthright citizenship in 1970? Yes.
Was Ted Cruz born in Canada? Yes
2 + 2 = 4
Ted Cruz is and was (until a couple of years ago) a natural born Canadian citizen
There is only one vehicle for Cruz to acquire US citizenship at birth. A Consular Report of Birth Abroad (CRBA) is the equivalent of a US birth certificate. Where is Teds'? Since Canada did not allow dual citizenship in 1970 a CRBA would have negated his Canadian birth. But it gets even worse for Ted. Without a CRBA technically Cruz is not even a US citizen. I would like to know what documents he used to get a US passport.
The idea that the son of a Cuban born in Canada is even a US citizen would have been considered absurd at the time our Constitution was adopted or anytime prior to mid 1930's.
