What law make Cruz a citizen?
^^^^^^
make = makes
Black Letter Law Dummy!
There are TWO and only TWO forms of Citizenship in the U.S. Natural Born “Birthright” Citizenship or Naturalized Citizenship.
Since it is a fact that Cruz is a citizen (NO ONE disputes this fact) and he is NOT a naturalized citizen which requires a legal process of becoming a citizen, he is by process of elimination a Natural Born Citizen.
