first thing is to get at least one state to make showing a long form birth certificate mandatory for running for the office of president.
Or sadly, the U.S. Armed Forces to get a prove that he is their legit C-i-C!!!
What if a long form birth certificate doesn’t exist for a person who is otherwise qualified? I am an American citizen born and raised in this country. When I joined the Marine Corps I didn’t have a birth certificate. I contacted the state I was born in (Oregon) and they sent me the certificate of live birth because according to them the original no longer existed. The Marine Corps was fine with what I had.
