I don't know if that makes either one of them Natural Born Citizens or not. The Naturalization Act makes them citizens, but not "natural born".
Can't you acknowledge that (1) the question needs an answer and (2) their situations are different for "natural born" status.
“Don’t you see the difference? “
It’s unclear what you are driving at. In any event, it is the question of whether or not the child is born with a divided allegiance of the United States.
Ted Cruz is born abroad as an alien born child with a U.S. citizen parent to qualify him to acquire U.S. citizenship at birth under the authority of Sec. 301(a)(7). Ted Cruz is born with allegiance to the sovereign of Canada due to place of birth, perhaps the sovereign Cuba due to paternity, and the sovereign United States due to maternity. There is no unity and sole allegiance to the sovereign United States, so naturalization is required to establish a form of U.S. citizenship other than natural born citizenship.
Marco Rubio was born within the jurisdiction of the United States with two foreign parents. Marco Rubio acquired U.S. citizenship by naturalization at birth under the authority of Sec. 301(a)(1). Marco Rubio was born with allegiance divided between Cuba due to paternity and maternity and to the United States due to place of birth. There is no unity and sole allegiance to the sovereign United States, so naturalization is required to establish a form of U.S. citizenship other than natural born citizenship.
