What a laugh. The only reason the DoJ is there this time is to maximize Democratic chances to defeat Walker. I suspect they will be very Jennifer Brunner-esque in their activities. That is to say, they won’t publicly pull anything blatantly fraudulent, but they will almost surely apply the most advantageous interpretation to any rules or authority they can invoke to affect the outcome.
Whoops, my bad. I didn’t read far enough to see it was the state level justice department at work here.
