This IS odd. All internet mentions of Carl Limbacher have been scrubbed. As if he's in a Stalin photograph, and became an un-person.
My favorite talk show caller nowadays is Jimmy from Brooklyn. He has a pretty encyclopedic knowledge of communist history and movements around the world. Savage and Bill Cunningham both take him seriously. Hannity always writes him off as a conspiracy nut and starts playing the Twilight Zone theme...just one more reason I find it hard to take Hannity seriously.
