Scott McClellan's departure is apparently only one-half of today's White House shake-up. As the Associated Press is reporting, Karl Rove is "giving up oversight of policy development to focus more on politics with the approach of the fall midterm elections."
Joel Kaplan, who was incoming Chief of Staff Josh Bolten's No. 2 man at the Office of Management and Budget, will get Rove's current title of deputy chief of staff for policy. Rove will apparently remain at the deputy chief of staff level, too.
