Dan Koh holds a commanding position in the Massachusetts 6th Congressional District Democratic primary, scheduled for September 1, driven by substantial fundraising advantages—over $4.5 million raised with more than $3.6 million cash on hand as of late June—and recent polling that shows him leading by double digits. Late July and early August surveys place Koh near 34 percent, ahead of John Beccia and Tram Nguyen in the mid-teens, amid a crowded field that includes several state legislators and local figures. The open seat, created by incumbent Seth Moulton’s Senate bid, has featured super PAC activity, television advertising waves, and debate scheduling disputes in August. Nguyen, a sitting state representative, maintains a smaller but notable share of support as the leading alternative, while remaining candidates trail further behind with limited resources and visibility. These dynamics reflect trader consensus on the race’s trajectory one week before voting.
