I haven't commented on the latest circus routine, but it is worth noting David Foster Wallace's Atlantic profile of the circus-master, John Ziegler:
KFI's John Ziegler is not a journalisthe is an entertainer. Or maybe it's better to say that he is part of a peculiar, modern, and very popular type of news industry, one that manages to enjoy the authority and influence of journalism without the stodgy constraints of fairness, objectivity, and responsibility that make trying to tell the truth such a drag for everyone involved. It is a frightening industry, though not for any of the simple reasons most critics give.
