In Louisiana, rules to participate in primaries vary by the office up for election. For congress, justice of the supreme court, the State Board of Elementary and Secondary Education, and the Public Service Commission, the state uses a semi-closed primary. In these primaries, only unaffiliated voters and voters registered with a party may vote in that party's primary. For all other statewide offices—including state senator and representative—Louisiana uses the majority-vote system. In this system, if a candidate receives a majority of the votes cast for an office, they win the election outright. If, however, no candidate reaches that threshold, a second round of voting is held between the top two vote-getters. Any registered voter can participate in both the first-round and second-round elections.[1][2]


This page focuses on Louisiana's 3rd Congressional District Republican primary. For more in-depth information on the district's Democratic primary and the general election, see the following pages:

Candidates and election results

Note: The following list includes official candidates only. Ballotpedia defines official candidates as people who:

  • Register with a federal or state campaign finance agency before the candidate filing deadline
  • Appear on candidate lists released by government election agencies

Beginning in the 2026 elections, Louisiana elections for U.S. Congress, the Louisiana Supreme Court, the Public Service Commission, and the Board of Elementary and Secondary Education use a closed partisan primary and primary runoff system. Candidates for those offices no longer run in majority-vote system primaries.

Note: At this time, Ballotpedia is combining all declared candidates for this election into one list under a general election heading. As primary election dates are published, this information will be updated to separate general election candidates from primary candidates as appropriate.
