Bill O'Reilly say's he's independent, yet He seems like More a Traditional Republican / Moderate republican?

If He's independent? What's he independent about? Or On, he never talks about his reasoning behind being independent. Other than the fact that he says he is , his talking points are all GOP Talking points, he agree's with the GOP on everything. He spend's 90% of his show railing against the President.. When Bush was President, he spent 90% of his show defending Bush...To me it seem's O'reilly is a Establishment Republican or Traditional. He's not Ultra right like Sean Hannity or Glenn Beck. His ideology is more in line with Bush- Senior Bush - Tom Coburn - Olympia Snow, a 1990's Republican.
