Must be, and Rush knows it because he has noticeably shifted his attitude towards the Cuban Cabana Boy if the last few days.
Nah, it's FR and other sites that have been hammering him. I'm sure he has a service that scours the media for mentions of himself, more so to gloat about being the first, id'ing salacious attacks by the LSM, er, "DBM" as he calls them, etc, and I bet that includes other like/dislike/ineffectual info.
Well, that and his call screener getting pounded about his Rubio propaganda from the first caller before the show to the last caller at the end, day after day, week after week, recent month after recent month.
His ego must be hurting from not succeeding with Rubio while denying it, and then from not being able to claim that FNC was "just following his lead" in toning down, if not effectively abandoning, Rubio marketing.
