He doesn't have to.
It should be up to him to prove it, not up to everyone else to simply accept his claims.,p> The onus is on those making the the charged to prove their case, not the one the charges are leveled at. The whole 'innocent until proven guilty' deal. And to date nobody has shown any evidence he was not born in Hawaii.
I'll bet that McCain, Palin, and Biden can all produce original, authentic birth documents and a supporting paper trail. Can Obama? So far seems not.
Because neither he, nor Palin or McCain or Biden...or Bush or Kerry or Gore are/were required to do so.
“Because neither he, nor Palin or McCain or Biden...or Bush or Kerry or Gore are/were required to do so (produce a birth certificate)”
But Obama is being sued because he apparently can’t provide a simple document that the others easily could provide.
