Democrat Scott Colom Wins Mississippi Senate Seat, CBS News Projects
A Democratic win in Mississippi, a state that last sent a Democrat to the Senate in 1982, signals a continued shift in Senate composition following the 2026 midterm cycle.
Democrat Scott Colom has been projected to win a United States Senate seat in Mississippi, according to a CBS News projection reported November 12, 2026. The race was described by CBS News as a "highly contested Senate battle" before Colom's victory was called. The win marks a significant shift in Mississippi's federal representation.
Mississippi last elected a Democrat to the United States Senate in 1982, when John C. Stennis won re-election. He served until 1989. Since that period, both of the state's Senate seats have been held by Republicans, according to official Senate historical records maintained by the United States Senate Historical Office.
Colom previously served as a district attorney in Mississippi's 16th Circuit Court District, covering Clay, Oktibbeha, and Webster counties, a position he held beginning in 2015, according to Mississippi state court records. His background as a prosecutor formed the centerpiece of his public profile entering the race.
The seat Colom is projected to win has not yet been officially certified by Mississippi state election authorities as of the time of this report. Certification timelines are governed by Mississippi Code Annotated Section 23-15-601, which outlines the canvassing process for statewide elections. The specific Republican incumbent or appointed officeholder whose seat was contested, and the precise vote margin, have not been confirmed in publicly available certified results as of publication.
The CBS News projection, delivered by correspondent Mark Strassmann, did not specify the vote percentage or the total votes counted at the time of the call, according to the CBS News video report published November 12, 2026. Those figures will be available in the official canvass report issued by the Mississippi Secretary of State's office.
Mississippi's shift comes amid a broader midterm environment that analysts have attributed in part to independent voter movement toward Democratic candidates. The Congressional Times reported November 12, 2026, that independent voters handed Democrats midterm gains, based on analyst assessments of the 2026 cycle results.
If certified, Colom's election would alter the partisan balance of the United States Senate. The precise new composition of the Senate following the full 2026 midterm cycle has not been finalized as of this report, as multiple races remain uncalled or uncertified nationally, according to the Associated Press race call tracker as of November 12, 2026.
Colom's campaign finance filings with the Federal Election Commission, including total receipts, total disbursements, and donor composition, are publicly available through the FEC's electronic filing database at fec.gov. Those filings provide a full accounting of which individuals, party committees, and political action committees contributed to his campaign and in what amounts. This publication has not yet reviewed those filings in full.
The Republican candidate who lost the race has not been named in the CBS News source material reviewed for this story. That candidate's identity, vote total, and any pending legal challenges to the result, if any, are not confirmed in publicly available records as of publication time.
What remains unknown is the final certified vote margin, the total voter turnout, and whether any formal challenge to the results will be filed. The Mississippi Secretary of State's official canvass report, once issued, will answer those questions. FEC filings by both campaigns will reveal the full financial picture of one of the most closely watched Senate contests of the 2026 cycle.
