Massachusetts Senate: Markey Heads Into Primary Day With a Wide Polling Lead
Massachusetts voters go to the polls Tuesday in a primary season that includes the state's marquee contest: 80-year-old incumbent Ed Markey's bid for renomination against Rep. Seth Moulton in the Massachusetts Senate race. A UMass Amherst/YouGov survey completed August 12 put Markey at 51 percent in a general-election trial heat against Republican John Deaton, with Deaton at 30 percent, but the more immediate question is the Democratic primary itself. An Emerson College poll cited by The Hill has Markey at 60.4 percent among likely Democratic primary voters, a double-digit cushion that suggests Moulton's challenge has not closed the gap heading into voting day.
The race has become a proxy for a broader argument playing out in several 2026 primaries: whether seniority and legislative tenure outweigh a generational contrast. Markey, first elected to the House in 1976 and to the Senate in 2013, has leaned on his record, including his authorship of the Green New Deal resolution, while Moulton, 47, has cast himself as the alternative on age grounds alone. The two met for a final televised debate in late August that produced sharp exchanges but no apparent shift in the trajectory of the race.
Money tells a different story than the polling. Moulton has outraised Markey overall, pulling in $6.2 million in total receipts compared with Markey's $5.4 million, according to FEC filings. Markey holds slightly less cash on hand than Moulton — $1.35 million to $1.84 million. That financial competitiveness has not translated into polling competitiveness, at least not yet, underscoring the limits of fundraising as a predictor of primary outcomes against a well-known incumbent. Outside race raters are not treating the seat as competitive in November regardless of the primary outcome: Cook Political Report, Sabato's Crystal Ball, and Inside Elections all rate the general election Solid D, Safe D, and Solid D, respectively.
Governor's Race: Healey Holds Wide Lead Over Minogue
In the Massachusetts governor's race, a University of New Hampshire poll ending August 24 shows Democrat Maura Healey leading Republican Michael Minogue 54 percent to 30 percent. That 24-point margin, combined with the lack of any competitive rating in the provided data, points to a race that has generated far less national attention than the Senate primary this cycle. No FEC fundraising figures for the gubernatorial candidates were included in the available data, limiting further comparison on the financial side of that contest.
House Money Race: Open Seat Fundraising Outpaces Some Incumbents
Massachusetts House fundraising figures show significant sums flowing into several districts. Daniel Koh reported $4.7 million in total receipts with $1.99 million on hand, while John Beccia raised $4.5 million with $750,000 remaining. Both are Democratic candidates, though the data provided does not specify which district each is running in or whether either is challenging a sitting member. Among sitting House members, Katherine Clark raised $4.5 million and retains just over $2 million on hand; Jake Auchincloss brought in $3.6 million in receipts but leads the delegation in cash reserves with $7.3 million banked; Richard Neal raised $2.5 million with $3.3 million on hand; and Lori Trahan raised $1.6 million with $1.77 million remaining. The disparity between Auchincloss's lower receipts and his outsized war chest suggests accumulated reserves from previous cycles rather than a surge in recent fundraising activity.
State Legislature: Record Number of Contested Incumbent Primaries
Beyond the federal races, Tuesday's ballot includes primary contests for all 160 Massachusetts House seats and all 40 state Senate seats. Twenty-six incumbents face primary challengers, the highest number since at least 2010, according to Ballotpedia. That volume of contested incumbent races points to unusual internal turnover pressure within the state's legislative majority, though the available data does not break down how many of those races are considered competitive or which incumbents face the most serious threats.
What to Watch
Results from the Markey-Moulton primary will be the headline number out of Massachusetts Tuesday night, testing whether Emerson's 30-point spread holds up against actual turnout. Down-ballot, watch how many of the 26 contested legislative incumbents survive — a high attrition rate would mark a notable shift in Beacon Hill's political dynamics heading into November.
