Dan Koh holds an overwhelming lead in the MA-06 Democratic primary market due to his dominant fundraising edge—over $4.5 million raised with roughly $3 million cash on hand—and high-profile endorsements from figures including former President Biden and former Labor Secretary Marty Walsh. As the open-seat race to replace Rep. Seth Moulton heads into its final week before the September 1 primary, Koh’s federal government experience and institutional backing have translated into consistent polling advantages. State Rep. Tram Nguyen trails as the main alternative, relying on her legislative record and local support in a field that also includes self-funded candidate John Beccia and several lower-profile contenders. Trader consensus reflects these resource and visibility gaps in the final stretch.
