Modifies provisions relating to elections

HB 2371 updates Missouri election laws to clarify who can vote, how to register, and the rules for absentee ballots. The bill sets the voting age at 17 years and six months, allowing eligible residents to register before their 18th birthday, while prohibiting voting for those adjudged incapacitated or currently serving prison sentences. It requires voters to present specific forms of identification, such as a birth certificate or driver's license, when registering and mandates that registration be completed by a set deadline before an election, with limited exceptions for military personnel and new residents. Additionally, the legislation expands the reasons a voter may request an absentee ballot to include employment as a first responder, health care worker, or law enforcement officer, and allows certain covered voters to use a federal postcard application to register and vote absentee.
