Or ... Rush is not ready to get into it. Or ... Rush is not 100% on the good side.
Of the options, I also think the following are possible:
1st Choice: At a time where the public is about to learn the MSM has been betraying them by taking intel leaks from the CIA daily at 4 am (Project Mockingbird still lives!), Rush needs to stay away from the appearance of accepting or utilizing intel leaks from the current adminstration(Q).
2nd choice: Conservatives are in jeopardy in the mainstream as it is; even speculating about the existence of Q would at the very least eliminate airtime.
3rd choice: He’s never heard of Q or doesn’t believe Q is legit.
