Do I detect some jealousy on Derbyshire's part -- given that he and his print media buddies no longer have a monopoly on the dissemination of conservative thought?
Kind of petty of you, Derb, ol' boy.
Not petty -- he's essentially correct in his analysis. Conservative talk radio doesn't disseminate "conservative thought." In it's current form it is little more than a mouthpiece for a few guys' personal opinions, presented in a manner designed to entertain and tweak the emotions of its niche (large, but niche) audience.
