Bill > HB1029

This bill establishes a closed primary system in Indiana, requiring voters to formally affiliate with a specific political party in order to vote in that party's primary election. Under the new law, voters may affiliate with a political party either when registering to vote or by submitting a party affiliation form, but they must do so no later than December 31 before the primary election. Each county voter registration office is required to mail a party affiliation form to voters by September 1, 2025, and voter registration forms must now include a section asking voters to choose their political party. Voters will only be allowed to vote in the primary election for the political party with which they are affiliated, and if a voter is not affiliated with any party or attempts to vote in a different party's primary, they will be prohibited from casting a ballot in that primary election. The bill aims to create a more structured primary election process by ensuring that only party-affiliated voters can participate in a specific party's primary, thereby potentially reducing crossover voting and strengthening party-specific candidate selection.
