I agree to a point. He could also go back to the biting satire and ridicule he was so good at in the beginning. Abortion updates with the sound of a vacuum cleaner - Slim Whitman's Paloma Blanca - A new IRS update theme using the Beatles Taxman, NSA updates using Secret Agent Man and etc. etc. One thing many fail to remember from Andrew Breitbart's brief but brilliant career was one of his axioms: "Politics is downstream from popular culture." The American pop culture is in such a spectacular ethics free fall that politics is almost invisible to the masses. JMHO.
I’m liking your retro-Rush programming thoughts and would only add the need for the occasional “caller abortion”.
