If the President is merely inept, incompetent and/or stupid, that's a matter for the ballot box to correct.
But if the President isn't Constitutionally eligible and may broken various laws in a quest for that office, that is a matter for the legal system.
The intent of the founders that the President be a natural born citizen with no divided loyalty to America and to some other foreign power(s) is very clear.
Even though “birthers” continue to be dismissed as nuts, the question remains, Why the secrecy? It certainly ought to be up to the president to prove that he is eligible for the job, not for the people to have to dig up the evidence that he isn’t. Even an birth certificate that proved O was born in the USA wouldn’t clear up all the questions about his citizenship, passports, etc. Time for him to live up to his “transparency” claim, or resign.
