The grandfather clause had nothing to do with James Madison choosing to become a Citizen of the French Republic as well as a U.S. citizen in 1792. And he was “The Father of the Constitution.”
Presidents James Buchanan and Chester Arthur had fathers born in Ireland; Woodrow Wilson’s mother was born in England; Herbert Hoover’s mother was born in Canada, Barack Obama’s father was born in Kenya; and Donald Trump’s mother was born in Scotland.
I agree that Martin Van Buren was the first president to ge a natural born citizen. The seven before him were born as British subjects.
Trump’s mother became a citizen 4 years before he was born.
Obama’s father was never a citizen.
Trump’s mother became a US citizen prior to DJT’s birth. Obama’s father remained a Kenyan.
Your dishonesty never ceases to amaze.
