He needs to do a lot more of it. I, for the most part, change stations when he takes calls now days. He used to have no patience for sycophantic callers. Now he lets them drone on forever about how much they love him.
He used to tightly manage that aspect of the show with seminars for callers and the shtick about the purpose of the caller being to make the host look good. He seems to have forgotten all of that, and will let any idiot or conspiracy theorist babble on and on for whole segments.
I’ve noticed the same response by Hannity, and Levin to some extent, recently. The caller will start off sweetly sucking up to the host, then start with a sing-song whine about “give Obama a chance”, blah blah blah. The host just listens and is overly polite. I, too, cannot stand it and turn the stations more than I used to.
