Jay Rosen, a communications professor, had an interesting blog entry on the reaction of political reporters and pundits to Rove's resignation. This is a quote from his entry:
Whereas I believe that the real—and undeclared—ideology of American journalism is savviness, and this is what made the press so vulnerable to the likes of Karl Rove.
Savviness! Deep down, that’s what reporters want to believe in and actually do believe in— their own savviness and the savviness of certain others (including operators like Karl Rove.) In politics, they believe, it’s better to be savvy than it is to be honest or correct on the facts. It’s better to be savvy than it is to be just, good, fair, decent, strictly lawful, civilized, sincere or humane.
While politicians and political reporters both love politics, there is a profound difference in the results of that love. When politicians and their helpers engage in politics, the purpose is not to be political, it is to gain power. With power comes the ability to make decisions that affect our society.
Political reporters, however, don't engage in politics at all, at least not in the sense of trying to obtain power. They are like sportswriters in that they are covering an activity that they love, but, like sportswriters, they can't play.
This means that they end up focusing on the part of politics that is concerned with winning elections as opposed to actually exercising power. Hence their love of writing about operators like Rove and their dislike for covering politicians who are actually interested in policy.
Combine those character traits with the fact that most political reporters who work for large corporations like Time, the Washington Post, CNN, Fox News, and others, don't really need government programs that help the average American, and you end up with a media that is just interested in being "savy" and not interested in actual policy. It is relatively easy for an intelligent guy like Karl Rove to manipulate those personalities.
