Louisiana holds a U.S. Senate race in 2026, on the ballot November 3, 2026, under one of the country's most distinctive election systems, a majority-vote "jungle" primary in which all candidates run together. Here's a nonpartisan guide.
What's on the 2026 ballot in Louisiana?
The U.S. Senate seat held by Republican Bill Cassidy is up, with the incumbent facing a notable intraparty challenge. Below it: all of Louisiana's U.S. House seats, state offices on their cycle, legislative races, and local contests. Louisiana does not elect its governor in 2026, that race runs in odd years.
What makes Louisiana's race distinctive?
Louisiana uses a majority-vote system in which every candidate, regardless of party, appears on the same ballot, and if no one wins a majority, the top two advance to a runoff. That changes strategy: candidates compete against the whole field at once, and a runoff is a real possibility that extends the campaign. The state votes reliably Republican in federal races, so the real contest is often within the party and in whether the incumbent clears a majority outright.
Why turnout decides Louisiana
Under a majority-vote system, mobilizing your supporters to clear the threshold, or to force and then win a runoff, is the whole game, and a midterm lowers turnout. Louisiana's early and mail voting and its diverse electorate, with a large Black population concentrated in its cities, make turnout and community-specific outreach both decisive.
