Dan Koh banks early cash lead in competitive Democratic primary race to succeed Seth Moulton
In his 2018 campaign for Massachusetts’ 3rd District, Koh was also a prolific fundraiser. He outraised Representative Lori Trahan, who narrowly defeated him in a recount in the primary for the open seat that year.
The $2 million haul would be a strong total for a statewide candidate, much less a candidate for House, putting Koh in a favorable position as candidates ramp up their efforts for the September 1 primary.
But other notable Democrats are running for this solidly blue seat, most of whom have demonstrated their ability to raise funds needed to compete.
Nearly all candidates entered the 6th District race in the two weeks after Moulton announced his decision to challenge Senator Ed Markey on October 15, except for software engineer Beth Andres-Beck, who was previously seeking to unseat Moulton. The first full fundraising quarter of the race will fall between January and March of 2026.
John Beccia, a cryptocurrency lawyer from Lynnfield, said in a press release his campaign has $1 million on hand, coming from a “mix of fundraising and self-funding.”
“This campaign has real momentum and we’re just getting started,” Beccia said.
Andres-Beck’s campaign did not provide overall fundraising numbers, offering instead that they had “over 4,100 contributions with an average contribution size of $21.62.” Andres-Beck reported raising over $108,000 in the third quarter of 2025, with $25,000 of that sum provided by the candidate.
“We’re still running this like the grassroot effort that the constituents of MA-06 have wanted since the beginning, and that Beth believes is necessary to bring much needed change to D.C.,” said campaign manager Prinxe Oliver.
Rick Jakious, Moulton’s former chief of staff, raised “nearly $300,000 by listening to voters in all 39 communities, not courting Washington insiders—and he’s just getting started,” said a Jakious campaign spokesperson.
The campaigns of Jamie Belsito, Topsfield town moderator and a former state representative, and state representative Tram Nguyen did not respond to requests for comment.
Moulton’s decision to run for Senate has created the first truly open race for the 6th District since the 1990s — Moulton won his seat in 2014 by challenging an incumbent — making this election a rare opportunity for North Shore Democrats with ambitions of advancing to Washington. It’s also the first House open primary in Massachusetts since 2020.
In addition to his fundraising totals, Koh has touted endorsements from high-profile national Democrats, like former Vice President Kamala Harris, as well as from local officials and key labor unions, like the International Brotherhood of Electrical Workers 103.
“The response to this campaign shows that people want leaders who are willing to do the work, listen first, and fight hard to get results,” Koh said in a statement.
