Four nights a week for sixteen years, Jon Stewart, the host and impresario of Comedy Centrals The Daily Show, has taken to the air to expose our civic bizarreries. He has been heroic and persistent. Blasted into orbit by a trumped-up (if you will) impeachment and a stolen Presidential election, and then rocketing through the war in Iraq and right up to the current electoral circus, with its commodious clown car teeming with would-be Commanders-in-Chief, Stewart has lasered away the layers of hypocrisy in politics and in the media. On any given night, a quick montage of absurdist video clips culled from cable or network news followed by Stewarts vaudeville reactions can be ten times as deflating to the self-regard of the powerful as any solemn editorialand twice as illuminating as the purportedly non-fake news that provides his fuel.
