A “natural born Citizen” is a subset of the super-sets of all U.S. Citizens and “born Citizens”. No person born with dual-Citizenship at birth is a “natural born Citizen”. Ted Cruz who was born in Canada and thus with Canadian citizenship, to a Cuban father and thus he inherited Cuban citizenship, and to a U.S. Citizen mother and thus inherited U.S. Citizenship; is a tri-Citizen at birth and is not a “natural born Citizen” of the United States. Marco Rubio was born in the USA and thus is a U.S. Citizen at Birth to two Cuban citizen parents and thus he inherited Cuban citizenship from both his parents; is a dual-Citizen at birth and is not a “natural born Citizen” of the United States.
