A phrase in Article II, Section I of the Constitution of USA states, “... or a citizen of United States at the adoption of this Constitution,” is a reference to those present for the writing, signing and adoption of the Constitution. Remember it was adopted in 1787. Many people present at the adoption were “native born” in England. The phrase “no person except a natural born citizen” is for all presidents in the future beyond those present at the adoption of the Constitution.
Ted Cruz is not a native-born U.S. citizen. He was born on Canadian soil. It does not matter, according to the Constitution, whether his mother was an American. Cruz is not eligible to be the president of the United States. Marco Rubio describes himself as a lawyer. I do not know what he specialized at, but he needs to brush up on what the U.S. Constitution outlines as qualifications for president of the United States.
