Washington Post: How Rove helped George W. Bush become President, how the Democrats wanted him to resign over Plame and the firings of the US Attorneys. Worth a Read, very fair article.
Time: Looking at the Rove myth and not finding much to be positive about, elections won yes but policy below a pass level. In other words a typical Liberal view of Karl Rove.
RealClearPolitics: A very positive article about Rove from an insider. Worth a read for some of the background details about Rove.
The New York Times: Not the greatest friend for Karl Rove but very informative article, covers the same areas victories but policy problems and investigations. Don't expect them not to be happy that he has left the administration.
