The Wisconsin Department of Motor Vehicles is reminding people how to get a valid I-D so they can vote in next month’s primary election. Potential voters can find the list of required documents they will need online at WisconsinDMV.gov. The closest D-M-V Customer Service Center can help you get the documents you need free of charge. Valid identification for voting includes a driver’s license, an identification card, a military I-D card, or a student I-D card. Many questions can be answered by the Wisconsin Elections Commission.
