Bill > HB2380

This bill makes significant changes to primary election procedures in Missouri, with a key focus on implementing a "protected primary election system" that restricts primary election participation based on political party affiliation. The bill requires voters to be registered with a specific political party at least 23 weeks before a primary election in order to vote in that party's primary. Voters will only be able to vote on the primary ballot corresponding to their registered party affiliation, with an additional unaffiliated ballot available for those not associated with an established political party. The bill also introduces new rules around changing party affiliation, candidate filing, and voter registration, including provisions that candidates must be affiliated with their party for at least 23 weeks prior to filing. The implementation of these changes will be gradual, with most provisions becoming effective on January 1, 2027. Additionally, the bill includes new cybersecurity requirements for election authorities and mandates periodic security reviews to enhance election integrity. These changes aim to create a more structured and controlled primary election process that ensures voters can only participate in the primary of the party with which they are officially affiliated.
