How An Election in Massachusetts Illustrates the Extent of Democrats’ Argument for Generational Change

On Sept. 1, 2026, Incumbent Democratic Senator Ed Markey (D-Mass.) fended off challenger House Representative Seth Moulton (D-Mass.) in the Massachusetts Democratic Senate primary. Markey’s win deviates from a recent string of Democratic lawmakers losing to younger challengers in other elections across Colorado, New York, Michigan and Connecticut, but aligns with a broader evolving progressive movement ahead of the upcoming midterm elections. 

Markey, 80, served 20 terms in the House of Representatives from 1976 to 2013 before resigning in order to run for, and ultimately win, a seat in the U.S. Senate in a special election following the resignation of Senator John Kerry (D-Mass.) to serve as the 68th U.S. Secretary of State under President Barack Obama. Markey subsequently served two full consecutive terms and is now seeking his third. He has been widely popular in Massachusetts after winning his first general election for the U.S. Senate by just over 66% in 2020 — following his initial win in the special election in 2013. 

Moulton, 47, has served Massachusetts 6th Congressional District in the House of Representatives, covering much of the North Shore, since 2015. In choosing to run against Markey, Moulton gave up his opportunity to be reelected in his current office. His campaign attacked Markey for his age and stagnance in the U.S. Senate, arguing it was time for younger voices to be let in. 

An attack ad from Moulton’s campaign joked: “Doctors agree: Democracy suffers when politicians won’t pass the torch,” emphasizing a broader argument being used across the country that older incumbent Democratic lawmakers need to let go of their roles and make space for younger candidates. 

Despite their wide age gap, Markey and Moulton aligned on many policy issues, and both framed themselves as progressive lawmakers. However, Markey was largely viewed as the more progressive candidate, since Moulton leans more moderate on certain topics — such as the rights of transgender athletes. Markey is already an established leader of his party’s progressive wing who has been advocating for left-wing policies — including protection for transgender individuals — for years. 

Both candidates supported expanding access to health care, but Markey argued for a single-payer Medicare for All system, aligning with progressive views. Moulton supported an expansion of Medicare with caveats for individuals who chose to hold onto their employer-provided health care, supporting a more moderate proposal. Both candidates are supporting Democratic agendas but Markey’s plan is more ideologically aligned with progressive goals. 

Progressive candidates have been defeating incumbent candidates across U.S. elections recently, but mostly in the context of a desire for age-based change, since the younger candidates are often also the more progressive candidates. In Connecticut, voters ousted Incumbent Democratic Representative John Larson (D-Conn.), one of the longest-serving Democrats in Congress, for Luke Bronin, a challenger who campaigned on generational change. 

“This is a political earthquake in Connecticut,” Bronin said on the day of his primary victory. “But the goal is to shake things up in Washington, D.C., and we’re just getting started.”

Markey and Larson both ran as incumbent Democratic candidates in two reliably Democratic states in New England, but their primary outcomes differed dramatically: Markey won with a sweeping 64.7% of the votes, while Larson garnered just 33.4% of the votes. Their challengers — younger up-and-coming politicians with substantially less experience in government — both targeted Markey and Larson’s age and stagnation, citing a need for generational change. 

The age-based attacks against Markey and Larson echo rhetoric that is being used in campaigns across the U.S. as midterm elections approach on Nov. 3, 2026. This strategy proved successful for politicians such as Bronin; Melat Kiros, a 29-year-old democratic socialist who defeated incumbent Representative Diana DeGette (D-CO) in Colorado; and Donavan McKinney who ousted incumbent Representative Shri Thanedar (D-MI) in the 13th Congressional District of Michigan. 

While these age-based attacks worked for young candidates in several other elections across the U.S., Markey’s victory suggests that generational change alone is not sufficient to sway voters. Despite facing many similar criticisms of age and stagnation, Markey won his election decisively, proving platforms still matter to voters. 

The age-based attacks against Markey were unsuccessful for Moulton, largely because of how progressive Markey’s platform was in comparison to the older incumbents running in other elections; Markey’s progressive track record acted as a “shield” against Moulton’s attacks. Much of the Democratic base may be dissatisfied with the “tired old status quo,” and want younger candidates in Congress, but Markey’s longstanding popularity highlights that if an older candidate is campaigning on modern and progressive plans, their platform might outweigh their age.  

Markey’s win emphasizes that age only goes so far with Democratic voters, and platforms remain essential, especially when both candidates share many similar progressive ideas. Ideological stances appear to matter more to Democratic voters than generational change alone, despite what the campaigns of many up-and-coming politicians across the country have been harping on. 

The Democratic Party is divided both ideologically. This division comes through in terms of contrast between moderate and progressive platforms, and on the importance of generational change. Markey’s decisive primary victory, in the context of significant Democratic incumbent losses, challenges the simplified rhetoric that Democratic voters are focused solely on making generational changes in Congress and highlights the nuance of voters in balancing a desire for younger voices with  progressive policymaking. 

“A lot of people tried to make this race about generational change,” said Representative Ayanna Pressley (D-Mass.), referring to Markey’s win, “It doesn’t matter if you’re young, if your ideas are old.”
