I must respectfully disagree. He has been certified by the States as being the Democrat Nominee for President - NOT that he is constitutionally qualified to be President. That is the substance of the Donofrio suit, which is currently in conference before the Supreme Court.
The State of Hawaii has certified that Obama has a birth certificate on record, but they have not indicated that the birth certificate actually says he was born in Hawaii. As another poster pointed out, his Indonesian-born sister has a COLB on file in Hawaii, too.
The burden of proof remains on Obama to prove that he is Constitutionally qualfied to be President. Of the three requirements (age, residency, and natural birth status), the birth certificate proves two of them.
NOT that he is constitutionally qualified to be President
That alone says it all.
