Modifies provisions relating to elections

This bill proposes an amendment to the Missouri Constitution to change how elections are conducted and who can vote. It would restrict voting rights to U.S. citizens over 18 who are state residents, while explicitly excluding individuals with legal guardians due to mental incapacity, those involuntarily confined in mental institutions, and people convicted of felonies or crimes related to voting. The amendment also limits voting methods to paper ballots or mechanical systems, ensures voters cast only one vote per issue or office, and mandates that the candidate with the most votes in a primary election is the only one allowed to appear on the general election ballot for that party. Additionally, it requires election officials to keep voter choices secret, with exceptions only for legal investigations or contested elections where ballots may be examined as evidence.
