A handful of stations -- none in Florida IIRC -- canceled their CBS affiliations as a "stunt" to garner conservative cred after the Bush documents affair. Among them WNIS Norfolk and KPRC Houston.
As someone else pointed out on this thread, WFLF still keeps a stealth affiliation with CBS, as apparently many other ostensibly "Fox News" affiliates do. That strikes me as tacit admission that the Fox News Radio product alone simply is not of sufficient quantity or quality to sustain a talk station with a significant "news" branding.
