Negative. He is affectionately lampooning his hero and mentor, William F. Buckley. Buckley, as you probably know, had some very unusual speech patterns, and in his television show when he introduced the Reverend Jesse Jackson, he pronounced it much like Rush does.
When Rush began his Sacramento show he drove around the area and hit a slum area on the fringe of Rio Linde. He decided to poke fun at the ritzy Rio Linde folk for the cars he saw sitting on blocks, the couches on the front porches, etc.
He is imitating the way Reiche introduced himself after his appointment to the Clinton cabinet.
