This one from Wisconsin. As in Farrakhan v. Gregoire, the main argument is that the state’s felony disenfranchisement law violates Section 2 of the VRA. But unlike Farrakhan and the other federal circuit court cases to have addressed the question, the Wisconsin case arises from a criminal prosecution for allegedly voting in violation of the state’s law. You can find Defendants’ brief in State v. Henderson/Maclin here and the State’s brief here. The circuit court judge appears to be taking the argument very seriously.
