There are different outlets for different people. The average political junkie that is here on the Q threads has already heard almost everything that Rush is going to say. The average Rush listener hasn't. I don't listen to Rush much, anymore, but Rush has 43 million weekly listeners, and most of them would tune out if he started talking about Q.
Y'know how they talk about red-pilling people? You can't give them everything at once, or they'll shut down. Rush is the into to conservatism.
Whatever role Rush was originally supposed to play has been forestalled due to his cancer diagnosis and treatment.
The Q Team may have determined he is unreliable. Not disloyal, but simply unreliable in the sense that no one, including Rush, can be certain how many days he may have to take off for treatment and rest.
It may be that when the Q word is uttered on the Rush Limbaugh Show it is done so by some honored guest host who gets that honor due to his past loyalty to the movement. He will thus be singled out as one of the major conservative voices of the future.
This would be done with Rush’s consult and blessing. He would be the maker of the next conservative broadcast king.
