Sure, I think there's a conspiracy that Rush isn't talking about RP.
But it's not any kind involving a conference room in an underground military bunker or anything.
Rush knows that if he starts talking about Ron Paul, he's going to start losing major face among not only the MSM but his own listeners. He is at the front line of the establishment neocons who get all their political news and commentary from the likes of him, Hannity, and to a lesser extent Glenn Beck and Mike Savage.
The number one reason we don't hear any neocon in the spotlight talking about Dr. Paul is very simple: his stance on the war in Iraq. If Rush starts talking positively about him, he's going to not only take a multi-faceted attack about being a flip-flopper on the war issue, but he'll have defense contractors ringing his phone off the hook asking him if he realizes the importance to the U.S. economy of continuing the war effort (read: lucrative defense contracts that keep Lockheed in business).
It's that simple.
Unfortunately, I don't think a compromise can be reached, because Dr. Paul's stance on Iraq is central to his government philosophy. And until we get some fresh commentators on the airwaves with points of view closer to the American public's, we're not going to hear anyone praising Dr. Paul.
