“not all citizens are natural born citizens.”
True. Some are naturalized under the authority of Congress. But those who are citizens by birth are natural born citizens, or native citizens. The terms were used interchangeably.
you are just wrong.
being born in the US makes you a citizen. at least a naturalized citizen.
if both parents are citizens at that time, then you are a natural born citizen.
if this was not the case, then any foreign dictator could squat a child on our shores, raise them elsewhere, and put them in the office. this was the situation the founders were pushing to avoid. hence the language.
“The terms were used interchangeably.”
Only by those who do not accept the intent of the founding fathers. (like democrats)
