Actually, he says quite clearly that he believes she is being persecuted for her pro-life position.
There are hundreds os Pro Life politicians, none of whom are being assaulted, period. For him to claim that her Pro Life stance is the reason why they are after her is an obvious lie and an intentional distraction.
O'Reilly isn't that stupid. He's just covering his own butt, toeing the party lines to make sure he remains in favor with the Beltway Sphincters. It's how he continues to have access to the DemRep weasels for his show.
He's selling snake oil, and that's not really so different from what the rest of the media is doing. Why I take exception to it is because, unlike the rest of the steaming pantload media, he claims to be "Looking out for us."
He's a phony and a charlatan who is going after Palin (in his subtle, vile, deceptive way) because she snubbed his show.
