I think he should do it, just to quiet all the questioning, and instead... all he's been able to do... is have another site (Fight the smears), post a photograph of a Hawaiin COLB(Certificate of Live Birth, Not a birth certificate), which (Assuming its real.... which Obama had never vouched for) can actually be produced without having been born in Hawaii.
