Rush, O’Reilly, and others make money telling us what they think we want to hear. They are entertainers - nothing more. I will admit that Rush played a large part in turning me into a conservative, though I think it would have happened anyway as I got older. Still, I don’t worship the golden microphone and am thankful we can get our news from a lot of different sources, the best being FR.
Some of these "conservative media personalities" are dumb as bags of rocks once they are off the air and out of their controlled environment. I don't necessarily include Limbaugh in this group, but you might be shocked at how mediocre some of his counterparts in the industry are.
