Washington — CBS News projects that Democrat Scott Colom has defeated incumbent Republican Sen. Cindy Hyde-Smith in the Mississippi U.S. Senate election. The result marks the eighth seat flipped by Democrats in the current election cycle, contributing to a projected 55-seat majority for the party in the upper chamber.
The race remained uncalled for several days following Election Day as officials tabulated votes. While early returns showed the candidates separated by only a few dozen votes, Colom’s lead grew as more ballots were processed. The outcome represents the first time a Democrat has won a U.S. Senate seat in Mississippi since 1982. Donald Trump won the state by 20 percentage points in 2024.
Colom, a 43-year-old district attorney, focused his campaign on healthcare and cost-of-living concerns. Hyde-Smith, 67, has served in the Senate since 2018 and was the first woman to represent the state in Congress. During the final weeks of the campaign, national Democratic groups invested in television advertising, and the Cook Political Report adjusted its rating of the race from "solidly Republican" to "leaning Republican" amid broader national trends involving inflation and the war in Iran.
On a national scale, this victory brings the Democratic caucus to at least 55 seats, compared to 44 for Republicans, with the Alaska race currently uncalled. This majority size provides the party with a larger buffer to confirm judicial nominees and executive appointments, as well as influence over committee assignments and the legislative calendar. The shift in Mississippi illustrates a change in voter behavior in a traditionally reliably Republican state, where national issues like the war in Iran and persistent economic concerns appeared to influence the local outcome.
The result confirms that Democrats will hold a majority when the new Congress convenes in January. For small-business owners, students, and healthcare recipients in Mississippi, the shift in representation may lead to different policy stances on federal programs or regulations starting next year. Following the conclusion of the "lame-duck" session currently underway, the newly elected senators will be sworn in.
