Obama has produced his official birth certificate. It was certified by the Republican Governor of Hawaii, Linda Lingle, as authentic. There are birth announcements documented from at least 2 newspapers in Honolulu at the time. The whole birth certificate conspiracy theory was debunked during the election. If there were any truth to it at all, Hillary Clinton would have killed him with it in the primaries. See:

It's easy to define what you're willing to fight for; but what are you willing to stand for without fighting? What are you willing to lay down your life for?
