Not sure if it will become conservative talk or not. Salem tried conserv talk here before and it didn’t well but they did just launch a new “Answer” on former Radio Disney station WDDZ (now WPGP) in Pittsburgh. Also they tend to run their own talkers (Gallagher, Praeger, Medved, Bennett); would they take Rush (...and pay for him?) In Pitt. they do have one local talker, Rose Tennant.
Its highly doubtful that a tiny squeaker like 620 KMKI Plano/Dallas is going to take Rush from WBAP 820 powerhouse.
