Going through some old files, dug up this clip on one of my favorite topics, Why The Media Isn't Necessarily Liberal. Reporters vote Democratic, but the institution as it functions is not liberal. Or, as Eric Alterman says in The Nation:

CNN does not cover trade from the perspective of the antiglobalization movement. It does not cover business from the perspective of the labor or environmental movements. It does not cover war from the perspective of the peace movement and it does not cover dictatorships (and illegal military occupations) from the perspective of their victims. It does not even cover George Bush from the perspective of the people who had their election subverted. Indeed, a recent study of the guests on Wolf Blitzer's Inside Washington recently found that the guests were more often Republican than Democrat, more often conservative than liberal. True, not all those who count as "conservative" are willing to go on record about Tom Daschle's supernatural satanic powers [as Rush Limbaugh did recently], but that's why we have Rush, Fox News, the Wall Street Journal editorial page, the Weekly Standard, the Washington Times, the New York Post, Matt Drudge, etc., etc.
