Letterman, whom I do watch, is becoming just as intolerable. I didn't watch when Bill Clinton was on the show last week -- I like my low blood pressure and my TV to much to risk either one. Your description of the Leno show fits Letterman like a glove as well, if not better; the slams on Kerry are about his horse-face, his touchiness with Edwards and, of course, Teresa (aka 'Ratwoman). The nightly bits about Bush's verbal stumblings are par for the course for a late-night funnyman (I've said it before -- Bush is the worst Presidential speaker in the history of recorded sound), but ever since the false CNN story about the White House allegedly accusing Letterman of doctoring a video clip of Bush, the punch lines have been about how stupid Bush is, mischaracterizing Bush Admin statements about WMDs, and suggesting that oil was the motivation for war in Iraq. It seems that Letterman refuses to believe that the CNN's retraction was genuine, and somehow, the White House called him a liar.
Have you never heard the Peanut President?????? Bush is absolutely eloquent when compared with cartbilly.
