The US Constitution has two criteria for being President. You have to be 35 years of age and a natural born citizen.
It doesn’t matter (in theory) where you went to college or who you married or how much property you own, if any.
And conveniently, there is one document every natural born American citizen has that proves you are Constitutionally qualified to be President.
That’s a birth certificate.
So showing yours should be a no-brainer if you are running, especially if for whatever reason, voters start mumbling about it/you.
