Democrat Scott Colom has won the US Senate seat in Mississippi, defeating Republican incumbent Cindy Hyde-Smith in one of the biggest surprises of the 2026 midterm elections. CNN's Decision Desk projected Colom as the winner on Wednesday, and Hyde-Smith congratulated him in a video posted to social media on Wednesday evening, bringing an end to one of the nation's closest and most closely watched Senate races.
Colom, a longtime district attorney, becomes the first Democrat elected to the US Senate from Mississippi since 1982, and the first Black Mississippian elected to the Senate since the Reconstruction era. The last Democratic senator from the state, John Stennis, was an avowed segregationist, and Mississippi's last Black senator, Blanche Bruce, was born into slavery. Colom opened his victory speech at the historically Black Tougaloo College on Wednesday night by honouring Mississippi's Black roots, naming Hiram Revels, the country's first Black US senator, and civil rights icons Fannie Lou Hamer and Medgar Evers.
The victory capped a campaign that transformed what was once considered a long-shot Democratic bid into one of the most closely watched contests in the country. Colom built his campaign around economic issues, government accountability and expanding opportunities in rural communities, and he drew support from national Democratic figures, including former President Bill Clinton, who campaigned for him in the race's final days, and former Vice President Kamala Harris, who appeared with him before 1,000 people at Columbus High School in Columbus.
The contest attracted national attention, and outside groups and party organisations poured millions of dollars into Mississippi, sensing an opportunity in a state Republicans had comfortably carried for decades. The effort was driven in part by Senator Raphael Warnock of Georgia, who had been pointing out since last November that the percentage of Black voters in Mississippi was higher than in Georgia, which had itself defied history to elect him twice.
Colom's path to the race began in an unlikely place. Running for Senate at all seemed like a long shot on an afternoon in November 2024, when Senate Democratic leader Chuck Schumer agreed to have Colom and his father over for lunch. Six months later, Colom was standing on the floor of his old high school gym in Columbus, challenging Donald Trump to a debate. The slogan that carried him through the campaign was simple: "Mississippi matters."
Hyde-Smith, who had served in the Senate since 2018, ran a campaign in which she was rarely seen, and her narrow defeat comes after a noticeably quiet eight years in the chamber. She had projected confidence in rare remarks to reporters in the Capitol hallways on Tuesday, but by Wednesday evening she had conceded. Her defeat is one of the most significant losses for Republicans in a midterm cycle that has seen the party suffer heavy losses in congressional and state races.
The reaction from Democrats was immediate. Schumer quickly hailed the result, posting on X that "Blue Mississippi is here", and Senator Cory Booker of New Jersey emphasised the historic nature of the win. Clinton celebrated the outcome on X, and Harris, who had campaigned with Colom during the race, also celebrated the victory. The result was widely described by national political observers as one of the biggest surprises of the 2026 midterm elections.
Colom's win is also significant for what it says about the politics of the South. Mississippi is the state with the highest proportion of Black residents in the country, and Colom's campaign argued that the state's voters had been taken for granted for too long. His focus on rural hospitals, many of which face closure because of Medicaid cuts scheduled to kick in over the weeks ahead, gave his campaign a concrete, local message that cut across party lines.
With Colom's victory, Democrats have extended their majority in the Senate, adding to gains that have already given them control of both chambers of Congress. The result will be felt in Washington, where the new Democratic majority will shape the agenda for the remaining two years of President Trump's term, and in Mississippi, where a Democrat will now represent the state in the Senate for the first time in more than four decades.
For Colom himself, the work begins now. He will take his seat in January, and his first task will be to deliver on the promises that carried him to victory: to protect rural hospitals, to hold the government accountable, and to prove that Mississippi, long written off by both parties, matters after all. His victory speech ended where it began, with the history he now carries with him into the Senate, and with the voters who made it.
