1) Many people, including some experts, have claimed that the certificate of live birth released by the Obama campaign wasn't legitimate. In all fairness to them, it can be difficult to judge some of the features needed to determine the authenticity of a birth certificate over the Internet. However, the people at FactCheck.org have seen the certificate of live birth provided from the state of Hawaii to the Obama campaign and it is genuine.
FactCheck.org staffers have now seen, touched, examined and photographed the original birth certificate. We conclude that it meets all of the requirements from the State Department for proving U.S. citizenship. Claims that the document lacks a raised seal or a signature are false. We have posted high-resolution photographs of the document as "supporting documents" to this article. Our conclusion: Obama was born in the U.S.A. just as he has always said.
So again, despite claims to the contrary, Barack Obama did provide a genuine copy of his birth certificate to the public.
2) Although Hawaii "state law prohibits the release of a certified birth certificate to persons who do not have a tangible interest in the vital record," the director of Hawaii’s Department of Health has certified that Obama does have a legitimate birth certificate on file in Hawaii.
3) In a print copy of the 1961 Honolulu Advertiser, there's a notice that Barack Obama was born. In and of itself, this is a game, set, match conversation-ender on this subject unless people want to argue that this isn't genuine or that there was a conspiracy going all the way back to the day of Obama's birth to make him President.
Quite frankly, this evidence is as definitive as it gets. Obama has a legitimate birth certificate on file, he released a copy of it to the public, and there is a news clipping that confirms he was born in Hawaii in 1961.
The latest tactic of the Birthers is to demand that the Supreme Court rule on this issue, but I would suggest to you that if the evidence that has already been made publicly available on this issue hasn't changed someone's mind, then having the Supreme Court rule that Barack Obama was born in Hawaii wouldn't do it either.
