Yeah, I agree. But I think he has other motives than just being "neutral" all the time. I think he's positioning himself, and Foxnews in general, to be the "go to" source for not only Prime Time news, but Prime Time entertainment in general for a major portion of the viewing audience.
In his mind, he can't get that kind of credibility by bashing liberals every night.
Just be patient with the guy. He's not the enemy.
