As his Election Law Blog Rick Hasen has a fairly thorough summary of the just-released Justice Department Inspector General’s report on the politicization of the Civil Rights division. The bottom line: liberal and conservative employees of the division did not play well with one another. The IG largely absolves attorneys within the division of engaging in improper conduct but (as Hasen notes) there are some close calls. In most cases, however, it appears that what one side considered improper conduct was simply the other side pursuing its vision of how the division should operate, and that such decisions are within the discretion of each administration and its political appointees.
