Both of these individuals are of Indian descent. Both had parents who were immigrants from India. In fact, Nikki Haley’s birth name is “Nimarata Nikki Randhawa”.
The United States Constitution has a clause that limits the presidency to “natural born citizens”. In order to interpret what this means, we have to discern what the founders would have understood the term to mean.
It does not merely mean a person who is born as a United States citizen. It means that the person’s father also must have been a United States citizen. The rationale was national security because you don’t want a person to be president who has divided loyalties.
The term “natural born citizen” is not the same as the term “naturalized citizen”. These terms have two different meanings.
Obama was not a natural born citizen and yet was permitted to assume the presidency. That had devastating effects.
It is doubtful that Haley or Ramaswamy will win the GOP presidential nomination– and they should not. But it is very possible they could be tapped as a vice-presidential nominee. That would also be highly inappropriate because a vice-president must necessarily be qualified to become president. And neither of these two individuals are qualified to become president.
