Remember to bring an acceptable photo ID for voting in the non-partisan primary election today. Our legal topic page on voting includes brochures and quick guides to what to expect at the polls, such as this City of Madison brochure: Recent Changes to Wisconsin Election Laws.
Generally you can check where you vote using the Voter Public Access database. However, if you are not sure about your polling place you can contact your municipal clerk's office for more information.
Polls are open until 8 pm. Learn more at the Government Accountability Board's website: http://gab.wi.gov/
