Well, if he's so capable as you claim, it makes it even worse that he represents the right so poorly on air, coming across as a non-serious jerk as he does much of the time.
When you listen to talk radio, there's one particular attribute of a host that really sets him apart from the others and makes him exceptionally good. Don Imus, for all his faults, took this skill and used it to make his show one of the most profitable in the history of talk radio. The on-air advertisements he reads are just as entertaining as the content of his show. Listen to Curtis Sliwa do a show from start to finish, and one of the things he does best is turn his advertisements into a storyline unto themselves. I haven't heard Curtis and Kuby's radio show in years, but I can still remember the names of some of their advertisers because of Curtis' comical portrayals of their products on the air ... "Kuby could use some o' 'dat Esotique by Chamonix ... he's got all 'doze wrinkles on his face from bein' angry wit' me for so many years."
There was a big ambulance-chasing law firm, Weitz & Luxenberg, that would advertise on their show. Curtis would read off their ad, which included a list of the types of cases they took, and he would add his own "editorial content" to the script: "The law firm specializes in recovering settlements from workplace injuries for their clients. So maybe you've had a fall at work, or injured your back ... or maybe you were minding your own business on the job and got tuned up by some hammerhead from Canarsie in a case of mistaken identity. Call Weitz & Luzenberg today ... they won't take a penny in fees unless they win a settlement for you!" Flipping to another radio station was never an option while you're listening to this kind of nonsense. LOL.
