Democrats’ generational battle erupts as 80-year-old senator faces younger challenger
Massachusetts held Democratic primary elections on Tuesday featuring a closely watched Senate contest between 80-year-old incumbent Sen. Ed Markey and 47-year-old Rep. Seth Moulton, reflecting a wider generational struggle within the party. Unusually, progressive figures are backing the older incumbent rather than the younger challenger, reversing the pattern seen elsewhere as Democrats grapple with age and leadership questions since Joe Biden's withdrawal from the 2024 presidential race.
Markey, a senator since 2013 after 37 years in the House, is supported by prominent progressives including Elizabeth Warren, Bernie Sanders and Alexandria Ocasio-Cortez, and is campaigning on issues such as the Green New Deal, Medicare for All and taxing billionaires. Moulton, a Marine veteran backed by New Jersey Governor Mikie Sherrill and endorsed by the Boston Globe, has made the case for age limits in politics central to his campaign, though he was forced to apologise during the race for earlier comments about transgender athletes in women's sport. Markey entered the primary as the clear frontrunner in polling and fundraising, with the winner set to face Republican John Deaton in the general election. The same ballot also features a six-way race to succeed Moulton in the House, primary challenges to several sitting Massachusetts Democrats, and a Republican gubernatorial primary to challenge Governor Maura Healey.

New here? Start with this
Ed Markey has represented Massachusetts in the US Senate since 2013, after decades in the House of Representatives. Seth Moulton represents a Massachusetts district in the House and is a former Marine. Both are Democrats seeking their party’s nomination for the Senate seat.
Their contest comes as Democrats debate age and leadership following Joe Biden’s withdrawal from the 2024 presidential race. Markey has the backing of prominent progressives and campaigns on policies including the Green New Deal; Moulton has argued for age limits in politics. The primary winner will face Republican John Deaton in the general election.
Both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Markey’s supporters can argue that voters should judge him by his record and current agenda, not his age alone: he has championed progressive priorities including climate action, expanded health care and higher taxes on billionaires. His experience and standing with prominent progressives may also help him advance those goals, while his strong polling and fundraising suggest substantial support among Massachusetts Democrats.
The case against
Moulton’s supporters can argue that elected officials need to reflect the generations they represent, and that age limits could encourage renewal and bring newer perspectives into political leadership. His challenge gives voters a chance to weigh Markey’s experience against the case for change, while Moulton’s support from other elected Democrats and a major newspaper offers backing for that argument.
