Massachusetts Democrats largely rewarded incumbency in Tuesday's primaries, with 80-year-old Sen. Ed Markey decisively defeating his challenger, 47-year-old Rep. Seth Moulton, in a marquee Senate contest. The results underscored the party's deep-blue stronghold status, as voters backed established figures across various factions and selected a Biden-Harris-backed candidate for an open House seat.
Markey's victory over the more moderate Moulton was seen as a win for the progressive wing of the Democratic Party. Moulton had argued for a generational shift, urging the party to "pass the torch," but Markey's long record and progressive bona fides resonated with voters. Despite facing campaign attacks regarding his stances on issues such as transgender athletes' participation in women's sports, the incumbent secured a clear mandate.
Following his concession, Moulton acknowledged the difficulty of unseating a long-term incumbent but stated the campaign initiated important conversations. He expressed confidence that others would be inspired to challenge the status quo.
The trend of incumbent success extended to the House of Representatives, where Reps. Richard Neal and Stephen Lynch fended off younger challengers. Reps. Katherine Clark and Jake Auchincloss also advanced, indicating a lack of broad anti-incumbent sentiment within the state's Democratic delegation.
In the 6th Congressional District, former White House aide Dan Koh secured the Democratic nomination for the open seat left by Moulton's Senate bid. Koh, who received endorsements from President Joe Biden, Vice President Kamala Harris, and other Biden administration alumni, aims to bring a new face to the delegation. Democratic National Committee Chairman Ken Martin congratulated Koh, highlighting his dedication to public service and focus on issues such as lowering costs, protecting healthcare, and affordable housing.
On the Republican side, the party struggled to field nominees in several key races. They failed to nominate candidates in four House districts, including the 7th District, where Democratic Rep. Ayanna Pressley will face no GOP opposition. Pressley ran unopposed in her primary.
Republicans will still have a statewide candidate in the gubernatorial race, with businessman Michael Minogue winning the GOP nomination to face incumbent Democratic Gov. Maura Healey, who ran unopposed. The GOP did nominate House candidates in five of the state's nine districts. In the open 6th District, Micah Quinney Jones will face Koh in the general election.
