I am more convinced every day that the only way to handle this thing is at the state level. If even one or two conservative state legislatures can vote to require that candidates provide documentary proof of natural born citizenship, 0 might be gone after one term for that reason alone.
Though, it can take as little as a state Sec. of State or election comission head to ask for proof of eligibility....birth cert....etc. The states have a lot of authority in how elections are handled....and Obama supporters would have a harder time in court
I don’t know how the last election affected things, but the lefties have been remarkably successful in electing SoS’s in recent years, with Soros’ money.
