Katie Couric and the CBS Evening News tie all-time ratings low.

Surprisingly, there are still 4.5 million people who are watching her every evening on average. I caught a few minutes of Couric recently, and I was struck at how I couldn't really notice any difference between her delivery and that of any other cable news anchor babe, except of course that she is older and less attractive in comparison with her younger competitors.

Is it the credibility? Well, I'm not sure what credibility she every had for hard news. She had been occasionally confrontational on the Today show and I guess that gets confused with gravitas by network executives. There is no sense that she is operating from a larger insight the way Peter Jennings or Tim Russert did.

She appears to be a perfect liberal-left-wing icon; a loyal partisan whose lack of talent and style was supposed to have been hidden by manufactured praise (brilliant! sexy! smart!) that in the end, just can't hide the figure flaws of this naked Empress.

Sound familiar? I'd venture to say that the entire left-wing establishment is in the same boat these days. Minority leader John Boehner called for the resignations or firings of Obama's entire economic team, which of course won't happen, but highlighted a political reality.

Various senior Democrats insisted that Tim Geithner had to be confirmed in spite of his tax problems, because he was uniquely qualified to deal with the financial crisis, there being NO ONE ELSE IN THE COUNTRY who could do the job....

Predictably, Geithner works alone these days for a simple reason--success has many fathers, but failure is an orphan.

Wheel barrels of praise, followed by epic failure, followed by embarrassment, followed by obscurity after they find some other poor sap to help them start the process all over again.

Are you listening General Petraeus?
