Primary Election Process
Closed Party Primary Elections in Louisiana
Starting in 2026, Louisiana will adopt a closed primary system for the following offices: U.S. Senator, U.S. Representative, Louisiana Supreme Court Justice, Public Service Commissioner, and the Board of Elementary and Secondary Education (BESE).
Only voters registered as Democrat or Republican may vote in that party’s primary. Voters registered with no party may choose to vote in either the Democratic or Republican primary, but not both. Voters registered with any other party cannot vote in closed primaries.
Most other offices will continue to use the open primary system.
Open Primary Elections in Louisiana
Louisiana uses an open primary system for most state, parish, and local elections. All candidates run together on one ballot, and any registered voter can participate regardless of political party.
If a candidate receives more than 50 percent of the vote, they are elected. If no one receives more than 50 percent, the top two candidates go to a runoff election.
This open primary system does not apply to presidential primaries or to certain offices that use a closed party primary.
If you have any questions about your state’s primary election, please contact your local election officials.
