"Birthers" as you call folks are not the ones who are required to prove anything. We are not the ones with access to documents or who have eligibility requirements to meet.
We do have prima facie evidence of FRAUD from the Obots in the form of Photoshopped official documents and Photoshopped pictures from the Acting President's pre-Chicago past. These ARE facts. In a more law abiding society, these folks would all be swinging from trees.

Did your "evidence" come from this guy?
