Democrat Dan Koh is projected to win Massachusetts's 6th Congressional District, according to Decision Desk HQ, securing the seat vacated by Rep. Seth Moulton (D). The projection came shortly after polls closed at 8 p.m. EST, with Koh's victory widely anticipated following his hard-fought primary win earlier this year.
Koh, who served in the Biden administration, defeated Republican Micah Jones, an Army veteran and attorney. The district, which leans heavily Democratic, was expected to remain in Democratic hands, and Koh's win continues the party's hold on the seat.
Koh's campaign drew significant support from high-profile Democrats of the previous administration, including former President Biden, former Vice President Kamala Harris, former Transportation Secretary Pete Buttigieg, and former Labor Secretary Marty Walsh. This backing underscored Koh's deep ties to the national Democratic establishment.
Koh's political career has been closely linked to Walsh. He served as Walsh's chief of staff during Walsh's tenure as mayor of Boston. In 2018, Koh ran for Congress but narrowly lost the Democratic primary to Rep. Lori Trahan (D-Mass.). After that setback, he joined the Biden administration, initially as Walsh's chief of staff at the Labor Department before moving to the White House, where he served as deputy assistant to the president and deputy director of the Office of Intergovernmental Affairs.
Koh's victory in the primary was seen as a significant achievement, given the crowded field and the district's competitive history. His win in the general election was never in doubt, but his primary victory set the stage for his ascension to Congress.
Moulton, who had represented the district since 2015, chose not to seek reelection, instead mounting a challenge to Sen. Ed Markey in the Democratic Senate primary. Moulton's bid to unseat the two-term senator was unsuccessful, ending his political career in the House.
Koh's win is part of a broader pattern of Democratic successes in Massachusetts, where the party holds all nine House seats. The 6th District, which includes parts of the North Shore and Merrimack Valley, has been a Democratic stronghold, and Koh's victory ensures that remains the case.
Looking ahead, Koh is expected to focus on issues such as economic opportunity, healthcare access, and infrastructure, aligning with the priorities he championed during his time in the Biden administration. His experience in intergovernmental affairs could also make him a key bridge between federal and local governments, particularly as Massachusetts faces challenges like the opioid crisis and housing affordability.
Koh's win also highlights the ongoing influence of the Biden administration's alumni in Democratic politics, as several former officials have successfully transitioned to elected office. His victory, along with other Democratic wins in the region, signals continued Democratic strength in New England.
