This year’s filing deadline for candidates running for the U.S. House of Representatives in Mississippi was Dec. 26, 2025.

Fifteen candidates — nine Democrats and six Republicans — are running for Mississippi’s four U.S. House districts. That’s 3.8 candidates per district. There were three candidates per district in 2024, 5.8 in 2022, 3.8 in 2020, 3.5 in 2018, 2.8 in 2016, and 4.3 in 2014.

Here are some other highlights from this year’s filings:

• No districts are open this year, meaning all incumbents — one Democrat and three Republicans — are running for re-election. There was one district open in 2018, the only election cycle since 2014 in which a district was open.
• Five primaries — three Democratic and two Republican — are contested this year. In total, there were three contested primaries in 2024, seven in 2022, five in 2020, three in 2018, three in 2016, and six in 2014.

• Two districts — the 2nd and the 4th — are tied for the most candidates running for a district this year. Three candidates are running in each district.
• Two incumbents — Reps. Bennie Thompson (D-2nd) and Mike Ezell (R-4th) — are facing primary challengers this year. There was one incumbent in a contested primary in 2024, four in 2022, three in 2020, one in 2018, two in 2016, and three in 2014.
• Candidates filed to run in the Republican and Democratic primaries in all four districts, meaning no districts are guaranteed to either party.

Mississippi is the only state holding U.S. House primaries on March 10, 2026. If needed, Mississippi will hold runoff elections on April 7, 2026.

In Mississippi, a primary candidate must win a majority of the votes cast for the office they seek to secure the nomination. If no candidate for an office wins a majority of votes cast in the primary, a runoff election between the top two vote-getters is held.
