Mississippi voters will choose Democratic and Republican nominees for Congress on Tuesday.   

All four of Mississippi’s incumbent U.S. representatives and its incumbent junior U.S. senator are running for reelection in 2026. Party nominees chosen Tuesday will compete in the general election on Nov. 3. 

Republicans hold slight majorities in both chambers of Congress. Mississippi’s congressional delegation currently consists of five Republicans and one Democrat. The only member of the delegation not on the ballot Tuesday is Sen. Roger Wicker, who isn’t up for re-election until 2030.

Here is a breakdown of the candidates in each primary.

U.S. Senate

Democratic Primary: Scott Colom, the district attorney for Noxubee, Clay, Lowndes and Oktibbeha counties, is competing against Marine Corps veteran Albert Littell and Priscilla Williams-Till, a distant cousin of lynching victim Emmett Till. 

Republican Primary: Incumbent Republican Hyde-Smith is competing against physician Sarah Adlakha in the GOP primary. 

Hyde-Smith has the power of incumbency, existing campaign infrastructure and the endorsement of President Donald Trump. But national Democrats believe the junior U.S. senator is vulnerable and have said they’re willing to pour money into the state to try to flip a Senate seat blue in Mississippi. 

U.S. House District 1 

Democratic Primary: Cliff Johnson, a University of Mississippi law school professor, is running against former Marshall County state Rep. Kelvin Buck.

Republican Primary: Incumbent Trent Kelly is running unopposed in the Republican primary 

U.S. House District 2 

Democratic Primary: Incumbent Bennie Thompson is running against Evan Turnage, a former aide to Senate Minority Leader Chuck Schumer of New York and Senate Conference Vice Chair Elizabeth Warren of Massachusetts. Thompson is also attempting to stave off a challenge from Pertis Williams III, who has focused on agricultural issues. 

Thompson has represented the 2nd Congressional District, which covers Jackson and the Delta, since 1993. Thompson, a civil rights leader and former chair of the House Select Committee investigating the Jan. 6th Capitol attack, is a towering figure in state and national politics. 

Republican Primary: Adams County Supervisor Kevin Wilson is squaring off against Ron Eller, a physician’s assistant and military veteran who is running again for the GOP nomination after losing to Thompson by nearly 25 points in 2024. 

U.S. House District 3 

Democratic Primary: Michael Chiaradio, a former baseball player turned regenerative farmer from New Jersey, is running unopposed for the Democratic nomination. Chiaradio told Mississippi Today he believes a localized message built around economic frustration can unite both disaffected conservatives and a fractured Democratic Party.

Republican Primary: Incumbent Michael Guest is running unopposed for the Republican nomination. Guest has sailed to general election victories three times since he was first elected in 2018. In 2024, he survived a primary challenge from the right that went to a runoff but ran unopposed in the general election.

U.S. House District 4 

Democratic Primary: Three candidates are competing for the Democratic nomination. They are Jeffrey Hulum III, a state representative from Gulfport, D. Ryan Grover, a business consultant who was the Democratic nominee for lieutenant governor in 2023 and Paul Blackman, a Navy veteran.

Republican Primary: Incumbent Republican Mike Ezell, first elected in 2022, is running against Sawyer Walters, who works for the Department of Marine Resources and serves as a lieutenant in the Mississippi Army National Guard.
