Democrat Scott Colom wins Mississippi Senate seat, becoming state's first Black senator in over 140 years

Democrat Scott Colom has captured Mississippi’s U.S. Senate seat in a historic upset, unseating Republican incumbent Cindy Hyde-Smith and becoming the state's first Black U.S. senator in more than 140 years and its first Democratic senator in more than four decades, according to The Associated Press (AP).

As per The Associated Press (AP), the tightly contested race was called on Wednesday after local election officials finished processing outstanding mail-in and provisional affidavit ballots from the November 3 midterm elections.

With nearly 99 percent of the vote tallied, the 43-year-old district attorney captured 49.19 percent (473,336 votes) against Hyde-Smith’s 48.71 percent (468,667 votes), while independent candidate Ty Pinkins received 2.10 percent (20,234 votes).

Under Mississippi election law, the state does not hold runoff elections for U.S. Senate contests or provide a statutory mechanism for recounts. Following the race call, Hyde-Smith telephoned Colom to concede and issued a statement wishing him well.

What historical milestones does Scott Colom’s Senate victory achieve?

According to CNN and Reuters, Colom’s victory breaks more than 140 years of racial exclusion in Mississippi's federal representation, making him the state's first African-American senator since the post-Civil War Reconstruction era—when Blanche Bruce was elected by the state legislature in 1874 and served until 1881—and the first Black senator from Mississippi ever elected by popular vote.

The upset also ends more than four decades of Republican dominance in Mississippi's Senate delegation, making Colom the first Democrat to win a U.S. Senate race in the state since John Stennis in 1982.

According to CBS News, the win gives Democrats their eighth flipped Senate seat in the 2026 midterm cycle, further expanding their newly reclaimed majority in the upper chamber.

Which campaign issues and political dynamics shaped the upset?

According to Reuters, Colom capitalized on voter frustration over economic pressures, surging fuel prices tied to the conflict with Iran, and an intensive grassroots campaign across rural and conservative communities in a state President Donald Trump had carried by nearly 23 percentage points in 2024.

The victory also carried personal political resonance, as Hyde-Smith had previously blocked Colom’s 2023 nomination by former President Joe Biden to serve as a federal district judge in northern Mississippi.
