Modifies provisions relating to the presidential preference primary

HB 2387 revises Missouri's election laws by establishing standardized election dates for most contests, requiring general elections on the first Tuesday after the first Monday in November and presidential primaries on the first Tuesday in March. It updates absentee voting rules to allow voters to request absentee ballots without providing a reason two weeks before an election and mandates photo ID for in-person absentee voting. The bill affects all Missouri voters, election administrators, and candidates by altering election timing and absentee procedures, while including exemptions for disaster-related bond elections, school tax elections during financial hardship, and special elections for vacancies. These changes directly modify how elections are conducted across the state.
