“No, they weren’t.”
The constitution explicitly states that those eligible for the presidency are either a Natural Born Citizen of the United States OR a citizen AT THE TIME of the WRITING OF THE US CONSTITUTION.
This is the ‘grandfather clause’, that Grandfathered the presidents born prior to the signing of the US constitution in 1787, presidents Washington through to van Buren.
In any case, once again - the constitution is right and you are wrong.
That's not exactly what it says, but I won't quibble.
In any event, those who were considered NATURAL BORN CITIZENS included George Washington, John Adams, Thomas Jefferson, Ben Franklin, James Madison, and everyone else who had been born in America. This has included every President ever elected.
Those who were NOT "natural born citizens" were people like Alexander Hamilton and James Wilson.
The grandfather clause was never used. Not even once.
And this is agreed upon by every real historian in history. Are you not able to read post #130? Or are you just a troll?
