Salon writer claims DOJ is trying to block Ohio law providing early voting to vets

At the link, Salon writer Joan Walsh claims that Romney is willfully misreading the Justice Department’s efforts to block an Ohio law that limits early voting to vets.  What in the world is she talking about?

Note to Salon Editor:  I know it is difficult to discern the difference between the Obama campaign and the Obama Department of Justice, but it is doubtful there is any truth that DOJ is actually involved in the lawsuit (except behind the scenes).  Waiting for the correction or simply removing the article altogether.
