No way. He basically endorsed Bush over Gore in 2000 and has been kind to Bush on some issues and hard on him on others. I think that O'Reilly is an independent (probably brought up Democrat but through life experience and education has learned how the economy and real world really work) with conservative personal values (Catholic who married and had kids relatively late).
All in all, O'Reilly is pretty fair and balanced, with a tilt to the right.
I agree with your conclusion. It would be a mistake to wish that our favorite news guy would always toe the consertative line.
All in all, O'Reilly is pretty fair and balanced, with a tilt to the right. I definitely agree. He just angers the far left 80% and the far right 20% of the time!
But those in the rigid right have no room to bend.
