Well, I don't think O'Reilly's any different than he's always been. I agree with him sometimes, and disagree with him other times. He backs up his assertions with facts, and, when he gives his opinion, you know it's his opinion.
And, O'Reilly has the highest rated prime-time cable show on television and his numbers, when they've varied, have varied upwards.
For some reason, people at Free Republic thought that he was a conservative, and are now disappointed to find out that he's not. I knew, from the first, that he was liberal on some things, conservative on others. He's an outstanding interviewer, and his show is interesting. It doesn't bother me that he's not an ideologue.
