Wikipedia defines Karl Rove this way: "the former Deputy Chief of Staff to President George W. Bush until his resignation on 31 August 2007. He has headed the Office of Political Affairs, the Office of Public Liaison, and the White House Office of Strategic Initiatives. Now he’s working as a political analyst and contributor for Fox News, Newsweek, and the Wall Street Journal."
My definition would be less kind and sure to include Joseph Georbells, a German politician and Minister for Public Enlightenment and Propaganda in Nazi Germany from 1933 to 1945. Georbells inclusion is intentional for the purpose of asking this question; Would you hire him after the fall of Nazi Germany as a political analyst for any media outlet? Then why has the U.S. media been so reckless calling on his services at a time when their own credibility is being called into question. Perhaps author James Moore of "Bush's Brain" put it best when he said this;
As the Democurmudgeon, I have been attempting to point out the elements of marketing; positioning and framing. Over the two Bush terms, Karl Rove has ruthlessly defined his enemies and crushed them, mastering the art of propaganda in politics as a blood sport. Too continue to allow his voice to subvert and poison the important role the media has as a checks and balance over the three branches of government is a mistake we can't afford to make.
