How another country determines citizenship by itself has no bearing on American citizenship.

My wife is a Canadian with a green card. Canada just passed a law making any children we have adopted Canadian, whether they are born in the USA, Canada, or Timbuktu. So, one day, our three children were not Canadian, and the next day they were. This change in Canadian law does not affect their American citizenship (all born stateside to two U.S. bio-parents) in any way shape or form. If my wife obtained dual citizenship and bore children on U.S. soil, the children would be naturally born U.S. and naturally born Canadian under the laws of the respective countries.

Under U.S. law, Ted Cruz was born a U.S. citizen by virtue of his mother's citizenship. He has never had to be naturalized, as he was naturally born a U.S. citizen, just as if he were born on an ocean liner in the Atlantic.

He was an American citizen at birth but he was a natural born Canadian citizen at birth. The Canadian law simply reinforces what the English common law states, what our founders stated, and what has been the opinion expressed in multiple SCOTUS decisions-that a natural born citizen is a citizenship established by virtue of the place of birth and by nothing more or nothing less.

No, I’m so sorry but no.
Ted Cruz, born of an American mother was entitled to apply for citizenship at birth. His mother or later he needed to provide documentation including his Canadian BC, his Mother’s BC, her proofs of residency etc. They would be vetted by the Consulate or if done later by the Dept Of Naturalization and he would be awarded citizenship if he met the criterion for citizenship. Ted Cruz has citizenship by statute not natural born citizenship.
