I have a feeling that in general news commentators attact the people in power. That is how they get their ratings.
My bet is that if the Democrats take the presidency in 2008, after a short honeymoon, he, and the rest will be after the president.
Better yet, for the newscasters, when the powerful are very unpopular.
We didn't just hear of Clinton's indescretions from Rush and Bill, everyone else piled on as well.
