Democrat Scott Colom wins Mississippi Senate seat, defeating incumbent Cindy Hyde-Smith

Mississippi has elected a Democrat to the United States Senate for the first time since 1982, after the Associated Press called the state's closely watched Senate race for Scott Colom on Wednesday, eight days after polls closed, a result PBS NewsHour and other outlets confirmed that evening. Colom, a Democratic prosecutor and former circuit judge from Columbus, defeated two-term Republican incumbent Cindy Hyde-Smith in a contest that remained too close to call for more than a week while county election officials worked through absentee and affidavit ballots.

The outcome makes Colom the first Black senator elected from Mississippi since Reconstruction, and it hands Democrats a seat in a state President Trump carried by 23 points in 2024. It is also one of the narrowest statewide results in recent Mississippi history, decided by a few thousand votes out of more than a million cast.

A margin that kept growing

With nearly all precincts reporting, unofficial tallies put Colom at roughly 49.2 percent of the vote to Hyde-Smith's 48.7 percent, with independent candidate Ty Pinkins taking about 2 percent, according to count updates reported by CNBC as results trickled in through Tuesday and Wednesday. Colom's lead widened steadily rather than appearing all at once: it stood near 2,990 votes early Wednesday and had grown to about 4,400 by midafternoon, as officials finished processing affidavit ballots in Hinds County, home to Jackson, where Colom was running more than four-to-one ahead of Hyde-Smith.

Mississippi has no automatic statewide recount provision, and county election commissions must forward certified returns to the Secretary of State's office within ten days of the election, a deadline that falls this week. Hyde-Smith's campaign had said for days that it would wait for "every legally cast vote" to be counted before conceding, and Colom's team avoided declaring victory outright until the Associated Press made its call.

A rematch rooted in a blocked nomination

The two candidates had clashed before. In 2023, Hyde-Smith withheld the "blue slip" needed to advance Colom's nomination to a federal judgeship on the U.S. District Court for the Northern District of Mississippi, a nomination President Biden had made at the recommendation of Mississippi's congressional delegation. She cited, among other objections, Colom's past campaign support from donors aligned with George Soros, a dispute chronicled at the time by the Mississippi Free Press. The blocked nomination became a central thread of Colom's Senate campaign, which he framed as a chance to answer directly to voters after being denied a seat on the bench.

Hyde-Smith, Mississippi's first woman elected to Congress, has held the seat since a 2018 special election that followed her appointment to fill the remainder of the late Sen. Thad Cochran's term; she won a full six-year term in November 2020, according to her official Senate biography. She sits on the Appropriations, Agriculture, Energy and Natural Resources, and Rules committees, assignments that will pass to her successor's party when the new Congress convenes in January, and her name still appears on the Senate's current roster of Mississippi's two members pending her replacement's swearing-in.

The race drew national money into a state that rarely sees competitive Senate contests. The Democratic-aligned Senate Majority PAC spent nearly $2.1 million on advertising, matched by a comparably sized buy from the Republican-aligned Senate Leadership Fund, according to AdImpact figures cited by NBC News. Colom's own campaign committee, Scott Colom for Senate, reported total receipts of roughly $4.4 million through mid-October, per its most recent Federal Election Commission filing — a sum that dwarfs what Mississippi Democratic Senate candidates have typically raised.

Exit polling reported by NBC News found that a majority of Mississippi voters disapproved of Trump's overall job performance, that majorities said his tariff policies had hurt the economy, and that majorities called it wrong for the United States to have taken military action against Iran. Those findings help explain how a state Trump won by double digits produced a Democratic Senate winner, even as Colom's personal appeal and Hyde-Smith's long record in office also shaped the result county by county.

Reaction on both sides

Hyde-Smith acknowledged the outcome Wednesday without disputing it. "While this is not the outcome we worked for or hoped for, I respect the decision of Mississippi voters," she said, adding that she wanted to congratulate Colom and that her campaign had "worked tirelessly to ensure every legally cast vote was counted," according to NBC News, which first reported both candidates' statements.

Colom, for his part, cast the win in language drawn from his campaign's closing argument in a heavily Baptist, heavily Black state where Democrats had written off statewide races for decades.

"We were never a lost cause. We were a betrayed cause," Colom told supporters, adding that "this journey started with a prayer" and that "in Mississippi, our prayers have often changed the course of history."

NAACP President Derrick Johnson, a longtime Mississippi civil rights figure, said the result showed what resources can do in a region national Democrats have often bypassed. "The Scott Colom campaign proves that it is possible to win in the South when there's investment," Johnson said.

What happens next

Colom's win is one of several Senate pickups that have given Democrats at least 55 of the chamber's 100 seats heading into the 120th Congress, with only Alaska's Senate race, where Democrat Mary Peltola held a narrow lead over Republican Sen. Dan Sullivan, still uncalled. Combined with Democrats' takeover of the House, the Mississippi result adds to a wave that has already reordered leadership fights in both parties, even as the specifics of committee assignments and seniority in the new Senate majority remain to be settled when lawmakers organize in January.

For now, the immediate step is procedural: county commissions must finalize their returns and forward them to the Mississippi Secretary of State's office for statewide certification, a routine process that is expected to confirm Colom's win in the coming days. Barring a legal challenge, which neither campaign has signaled it will pursue, Colom is set to be sworn in alongside the rest of the incoming Senate class when the new Congress convenes on January 3, succeeding Hyde-Smith after eight years in office and ending a 44-year Republican hold on one of Mississippi's two Senate seats.
