The LEFT graced lord McCain as eligible well before the Berg question got filed. BamBam knew/knows his eligibility status and he has kept silent and hides all historical documentation of who he is. Hindsight being 20/20 Hillary would have not taken for granted that her destiny was in stone and would have made darn sure BamBam's eligibility was in question from the 'get-go'. Politically speaking she was brain dead and did not see the possibility of her NOT being the nominee until it was toooooooo late to save it.
McStain was an open target for question, in that he was born in Panama, and maybe not really in the Canal Zone.
I do not know when the Obambie birth issue came up.
I do not think it was even on the radar screen at first.
Keep in mind, I have not been in the USA since Jan. 2005
and had no idea who Obama was. I had never heard of him.
I think someone, far too late, saw flaws in the bogus certification, pointing out that anyone could walk in off the street and get one.
That is when people started taking names and asking questions.
Everything about Obambie is questionable.
If he were a Republican he would be in jail by now.
