I'd be shocked if WLS dropped Limbaugh, but Cumulus has been known to do the unexpected.
KSFO the Cumulus O&O in San Francisco dumped Rush on New Years Week and Rush went to KKSF 910 AM the CC station in SFO. Also Cumulus fired Gene Burns, Len Tillem and Gil Gross (sometimes on ABC Hourly News) on the other Cumulus O&O KGO and these talk hosts went CC's KKSF 910. Look at Cumulus O&O KGO-AM 810 its a Merlin Wannabe because they do all news the same way WEMP in NYC does the all-News format.
I like to know how many Cumulus O&O's went All-News using merlin Tactics besides KGO?
