Either one of three options takes place:
1) CC flips either 104.5 or 106.1 to an FM talk format. It would be more likely if CC/Premiere wanted to break Rush's contract with WPHT, although if that was the case, CC would have done so already. Greater Media won't do anything, obviously because they won't have the possibility to poach Rush like CC could.
2) Salem's WNTP picks up Glenn Beck (and Hannity as well) shuttling off Mike Gallagher and Micheal Medved to the late night hours. All they need to do is drop Savage and Dennis Miller - which for some oddball reason only air back-to-back from midnight-5am.
Glenn Beck has really benefited from Salem adding the show on their conservatalkers in Chicago, Dallas, Los Angeles and Lancaster CA, and Washington, DC. (The DC clearance also came after CBS pushed Glenn off of their abysmal WHFS/1580 in favor of infomercials.) What also helps is the fact that Salem often pushes Gallagher's show off into obscure time-slots as it is; he's not live in any of the aforementioned cities, nor is he live in his home market of New York.
And don't forget Salem's clearance of Hannity on KNUS in Denver (and also cleared it on the former WTTT/Boston).
3) Neither Beck or Hannity gets picked up by any station whatsoever, and fans will have to listen to suburban signals instead. That's not likely at all IMO.
