Quite a few presidents weren’t natural born citizens.
The first ones exempted themselves with, “or a citizen at the time of”, because there couldn’t be any natural born citizens for a while. The only questionable one before The Usurper was Chester A. Arthur and he went to great pains to destroy any evidence so we don’t really know one way or the other.
Really which Presidents weren’t natural born? You can exclude the founding fathers and anyone who was a citizen of the US at the time of the signing of the Constitution. They are eligible via the Constitution. Please name two.
Yes, the first Seven, Chester A Arthur and the current one.
The first seven were grandfathered in, Chester A Arthur lied about it, and the current one came along when the nation has descended into idiocy and could no longer remember basic foundational principles.
But the other 36 were natural citizens.
