Scott Colom has won Mississippi’s U.S. Senate race, defeating Republican incumbent Cindy Hyde-Smith after election officials spent more than a week counting outstanding ballots.
The result, called Wednesday, November 11, gives Democrats a major upset in one of the country’s most reliably Republican states.
Hyde-Smith has conceded the race, while the results remain subject to Mississippi’s certification process.

Scott Colom defeats Cindy Hyde-Smith
Colom, a Democratic district attorney from northern Mississippi, finished ahead of Hyde-Smith in a contest that remained too close to call for days after the November 3 election.
The latest reported count showed Colom with roughly 470,000 votes, or about 49.1 per cent, compared with approximately 467,000 votes and 48.8 per cent for Hyde-Smith.
Independent candidate Ty Pinkins received about 20,000 votes.
The margin widened as counties processed absentee and affidavit ballots.
Colom held only a 43-vote advantage after an early election-night update, but later batches increased his lead to several thousand votes.
Mississippi Secretary of State Michael Watson’s office has said counties have 10 days from the election to submit certified results.
That deadline is Friday, November 13.
A historic result for Mississippi
Colom is set to become Mississippi’s first Black U.S. senator since Reconstruction, the period following the American Civil War when Black lawmakers served in state and federal office across the South.
His victory also ends a decades-long run of Republican control over Mississippi’s U.S. Senate delegation.
Hyde-Smith had held the seat since 2018 and was seeking her second full term.
The outcome is particularly significant because Republicans have dominated statewide elections in Mississippi for years.
President Donald Trump carried the state by a wide margin in the 2024 presidential election, and Republicans continue to hold most major statewide offices.
Why the race took so long to decide
Mississippi’s election system is administered from the county level.
Local circuit clerks and election commissioners count ballots and submit results to the secretary of state.
The count continued after election night because officials still had to process absentee ballots and affidavit ballots.
Affidavit ballots are provisional votes cast when a voter’s eligibility or registration information requires additional review.
The secretary of state’s office said before the race was called that thousands of absentee ballots and an unknown number of affidavit ballots remained in the process.
Those ballots were reviewed by county officials before being included in updated totals.
The prolonged count drew national attention because the margin was initially so narrow that relatively small batches of ballots could have changed the result.
What happens next
Mississippi counties must complete their certifications before the statewide result can be finalized.
The state’s election authorities will then compile the certified returns.
The reported result could still face legal challenges, although any challenge would have to proceed under Mississippi election law and would not automatically change the outcome.
Colom will take office in January 2027 if the result is certified and any legal proceedings do not alter the outcome.
He will join a Senate reshaped by the 2026 midterm elections.
For Hyde-Smith, the defeat ends her tenure in the Senate but not necessarily her public career.
She entered the chamber in 2018 after winning a special election and later secured a full term in 2020.
What Colom campaigned on
Colom focused his campaign on the cost of living, wages, rural health care and issues affecting Mississippi communities.
His support was strongest in heavily Black areas, but he also made gains with some white voters and younger voters compared with recent Democratic statewide performances.
The result suggests that Mississippi’s electorate remains strongly conservative but is not immune to competitive statewide campaigns.
Turnout, candidate-specific factors and the national political environment all played a role in producing an unusually close Senate contest.
Colom’s victory will now make Mississippi one of the most closely watched states in the new Senate, both because of its historical significance and because of the narrow margin by which the seat changed parties.
