Some thoughts on Karl Rove, from the head of the state Democratic party. Joe Wineke says it's really no surprise that Rove, perhaps the key behind the scenes player in the Bush White House, is taking his leave of the administration now rather than later. Rove "has largely outlived his usefulness," after presiding over the GOP loss of Congress, says Wineke. Wineke calls Rove "an attack dog" largely responsible for a tone of partisan negativity in D.C. these days. And Wineke insists there's really no one like Rove in his party. Wineke expects Rove will now "ride his black horse off into the sunset, and write a book."
