Here.  Analyze this blurb from this recent article:

The ACLU, the ACLU of Wisconsin and National Law Center on Homelessness & Poverty filed the complaint on behalf of state residents who may not be able to vote under the law. 

Note the speculation in the language: "on behalf of state residents who may not be able to vote."  There is only rank speculation in this complaint and no actual evidence of anyone not being able to register to vote, obtain adequate photo identification, much less cast a vote.
