Wisconsin has one statewide ballot measure appearing on the April 1st ballot. This measure, if approved by voters, would enshrine Wisconsin's current photo identification requirement for voting into the state's constitution. Currently, Wisconsin's photo ID requirement for voting is a state law - this ballot measure, if passed, would further support and solidify that law.
