He won't be the last, but he certainly wasn't the first. In fact, former Arkansas Gov. and Republican presidential-candidate Mike Huckabee is just the latest among many high-profile figures to recently proclaim the demise of the 4th estate:

I’m sad to report today a death of a good friend to all of us…..Journalism, the once esteemed 4th estate of our nation and the protector of our freedoms and a watchdog of our rights has passed away after a long struggle with a crippling and debilitating disease of acute dishonesty aggravated by advanced laziness and the loss of brain function.

  • The Atlantic's Own Mark Bowden says political hit men are the new journalists: "In this post-journalistic world, the model for all national debate becomes the trial, where adversaries face off, representing opposing points of view."
  • The president of the United States used the occasion of Walter Cronkite's death to talk about that of journalism itself. But don't worry, he offered hope for its resurrection: "If we choose to live up to Walter's example, if we realize that the kind of journalism he embodied will not simply rekindle itself as part of a natural cycle but will come alive only if we stand up and demand it, and resolve to value it once again, then I'm convinced that the choice between progress and profit is a false one and the golden days of journalism still lie ahead."
  • And of course, all know about journalism-major Sarah Palin's feelings on the matter: "When did we start accepting as hard news sources bloggers, anonymous bloggers especially? It's a sad state of affairs in the world of the media today, mainstream media especially, that they're going to rely on bloggers, anonymous bloggers, for their hard news information."
  • LA Times writer Michael McGough blames the departed Robert Novak and others of his ilk: "But in his later career Novak was known less as a reporter and more as an opiner and television talking head. His metamorphosis says a lot about the evolution (or devolution) of Washington journalism."
