The Framers didn't say "show birth certificate." So it's not a requirement. What *IS* a requirement is proof that someone is a "natural born citizen."
The Framers DID say, at Article 4, Section 1:
Full faith and credit shall be given in each state to the public acts, records, and judicial proceedings of every other state. And the Congress may by general laws prescribe the manner in which such acts, records, and proceedings shall be proved, and the effect thereof.
Hawaii proved and published documentation of Obama's birth, just as the Framers stated in the Constitution. And the Framers said that when that is done, "Full faith and credit shall be given in each state to the public acts, records, and judicial proceedings of every other state." That applies even in the State of DiogenesLamp.
Nobody is questioning a record from Hawaii that actually proves birth in Hawaii. They just haven't submitted such a record, nor are they required by law to create one.
Their document is not the equivalent of similar documents created in other states. It does not serve the purpose of proving birth in the state.
And they haven't even shown us an original document.
Hawaii proved and published documentation of Obama's birth
They showed documentation of his birth, but they haven't proven it occurred in Hawaii.
