Seems to me the constitution has an exception for those who were born before there was a USA. Otherwise we would have had babies or foreigners as POTUS.
Washington was born in Virginia
John Adams was born in Massachusetts,
Thomas Jefferson was born in Virginia,
James Madison was born in Virginia,
James Monroe was born in Virginia,
John Quincy Adams was born in Massachusetts,
Andrew Jackson was born in the North/South Carolina area William Henry Harrison was born in Virginia
This listing of our first presidents and their places of birth raises the question(s): if each of them was born in what was to become the United States of America and after the American Revolution became automatically its citizens, why did the Framers find it necessary to specify that the holder of the Office of the President, and only that office, be a “Natural Born Citizen?” Why wasn’t “citizen” adequate for that office as it was for the other offices enumerated in the Constitution?
