Reinstates the presidential preference primary and modifies provisions for absentee voting

HB 367 reinstates Missouri's presidential primary election to be held on the first Tuesday in March during presidential election years, replacing the current system. It modifies absentee voting rules by requiring photo identification for mail-in ballots (unless voting due to specific reasons like incarceration or address confidentiality program participation) and expanding eligible reasons for absentee voting to include religious observance, certain employment (e.g., first responders), and financial hardship in school districts. The bill directly affects Missouri voters participating in presidential primaries and those seeking absentee ballots, particularly incarcerated individuals, participants in address confidentiality programs, and voters with religious or occupational constraints. Key provisions include new requirements for absentee ballot envelopes and streamlined registration via federal postcard applications for eligible voters.
