The issue is the Constitutional requirement that the POTUS be born in the USA. The burdon of proof is on Obama not us. Why is he being so coy about it? Embarassment? We already know his father was an alcoholic bigamist and his mother was a ditzy left wing flower girl. What's left to hide?
The only "burden" Obama had was to prove eligibility in the '08 election,
which he did as verified by the State of Hawaii in accordance with federal election law.
That's the
end of the debate, legally speaking. Birthers don't understand that they don't get to impose additional legal burdens simply because they aren't personally satisfied. I don't blame Obama for not capitulating to the demands of the inherently unreasonable.
