Former Biden White House aide Dan Koh has won the crowded Democratic primary for Massachusetts' 6th Congressional District, a seat vacated by Rep. Seth Moulton. Koh positioned himself as a candidate with deep ties to the Democratic establishment, actively campaigning with endorsements from former President Joe Biden and former Vice President Kamala Harris, as well as support from former Labor Secretary Marty Walsh.
Koh's campaign significantly out-raised his opponents in the five-way primary. He also benefited from over $700,000 in spending from Think Big, a super PAC affiliated with the pro-AI Leading the Future network. Koh previously served as deputy cabinet secretary in the Biden White House, overseeing communications, policy, and logistics between the White House and federal agencies. He also held positions as chief of staff at the U.S. Department of Labor and was a member of the Andover Select Board.
Koh stated his aspiration is to improve government's ability to help people and to lower costs for constituents. He acknowledged public disillusionment with politics and corruption, aiming to restore faith in government. In contrast, other candidates in the primary emphasized an anti-establishment, outsider message. Koh is expected to be the favorite in the general election in the heavily Democratic district.
