Generally revise laws related to voter list maintenance

This bill updates Montana's voter registration maintenance laws by requiring courts and the Department of Motor Vehicles to share address change information with county election administrators. It mandates that election administrators annually compare voter lists against national address databases and utility company records, while also sending confirmation notices to registered voters to verify their addresses. The bill establishes procedures for moving voters to inactive lists if they fail to respond to verification attempts and requires these processes to be completed at least 90 days before federal elections. These changes directly affect county election administrators, the Department of Motor Vehicles, courts, and registered voters by creating new data-sharing requirements and verification steps.
