To my knowledge, nobody has ever seriously challenged a candidate's birthplace or age (the rumors that Chester A. Arthur was born in Canada never led to a contest). No candidate for the presidency has ever had to prove his age or place of birth that I know of, nor has one ever been required to produce a birth certificate.

Presumably, if that was in doubt, there would be a lawsuit of some sort at which point evidence of all kinds, including birth certificates would be admissible.

Not only do we need to see his birth certificate, but we need to see his baptismal record.
I doubt if it exists, after all, Obama’s church said they have many Muslim members.
