It's not hurting him among his supporters, and I suggest that the mighty hand of God could descend from the clouds with a copy of Obama's birth certificate and most of those now opposed to him would still say, "Yeah, but...".
AOL’s poll indicates he is hurting himself with a far wider group than FReepers.
And it is false that the vast majority of us would not accept a valid birth certificate something he has NOT produced no matter your belief that he has.
Should he direct Linda Lingle to release it to the media and it is valid we will grin and bear it.
