That's why its very enlightening sometimes to listen to the other points of view - confirming our core beliefs! Even if privately O'Reilly knew W is the only clear choice, he won't go out on a limb to say so. But...showing Kerry's old interview was like he said interesting. If he was so stuck on Kerry he wouldn't have run his old interview with him saying the opposite what is now Kerry's current stance on Iraq. O'Reilly keeps you guessing - I think that's not necessarily a bad thing.
I think Oreily did a ratings analyis and figured if he could fake being Rush lite he would be able to be bigger than Rush. He is not honest, he just dives to the percieved middle, which the MSM has established as left. (homosexual adoption, civil unions, opposing FMA)
