Dan Koh holds a commanding position in the MA-06 Democratic primary, driven by his substantial fundraising edge—more than $3.6 million cash on hand as of late June—along with prior roles as a White House and Labor Department official and Boston mayoral chief of staff. The September 1 primary for the open seat follows incumbent Seth Moulton’s decision to seek the U.S. Senate nomination. State Representative Tram Nguyen, the leading alternative with an immigrant-refugee background and focus on affordability, trails significantly in resources and polling. Recent candidate forums and an internal poll released by the Koh campaign have reinforced his frontrunner status ahead of the vote, while the crowded field of lesser-funded contenders shows limited momentum.
