On whom is the burden of proof? Those who doubt his citizenship, or on the man who wants to be Head of State, Chief Executive, and Commander-in-Chief?It's on the doubters. The existing and easily obtained evidence supports the fact that Obama was born in Hawaii to an American mother. There is no credible evidence to the contrary. Obama's refusal to release his original birth certificate is all they have, and since he isn't under any legal obligation to release this document, it's a pretty weak case.
There is no “existing” evidence that Obama was born in Hawaii.
