Revise election laws related to active and inactive voter lists

This bill updates Montana election laws to establish specific procedures for maintaining active and inactive voter registration lists. It requires election administrators to annually compare voter records with national address files and mail confirmation notices to registered voters, including those who did not vote in the last federal general election. If voters do not respond to these notices within 30 days, their registrations are moved to an inactive list, and the state works with the motor vehicle division to verify their addresses. The bill mandates that these procedures be completed at least 90 days before any primary or general election for federal office and applies immediately upon passage.
