Palin isn’t qualified? And Obama is?
Neither 0bama nor Palin are qualified. 0bama didn't become POTUS because of his qualifications...he became POTUS because the media had a love affair with him and didn't vet him. Unfortunately, Palin is not loved be the media...they will do anything to destroy her. The treatment Christine O'Donnell got from the media is nothing compared to what Sarah Palin would get if she ran.
One benefit of her running, though, is that she would draw all of the negative attention from the media during primary season...then when another Republican wins the nomination it will be difficult for the media to do that same to that candidate.
