I don't think you can call Oreilly a cheerleader for the right. He comes down pretty hard on the neocons. I think he has an ego, but he trumpets his views not the agenda of the right.
Unlike the clearly conservative Hannity, O'Reilly is actually neither left nor right. He's a populist. He only seems "right wing" in comparison to the center-left reporters and commentators on most other network shows.
