Does the media need to hire more conservatives?

In a switch from the norm, Thomas Frank (the Wall Street Journal's token moderate commentator) writes about Washington Post ombudsman Andrew Alexander who said the media is too liberal and needs to hire conservatives (I'm paraphrasing Alexander, but this is the gist of what he's written). Frank points out the media is quite conservative already (no questioning of the run up to the Iraq war or, frankly, much else at the Bush White House until the final couple of years when it imploded, or questioning the banking industry as it took America down).

Hearkening back to basic journalism 101, Frank says what is needed is a media willing to hold power accountable. More power to him and his views.
