Overview
Updated 3 hours agoBoston Mayor Michelle Wu turned a policy defeat into a personal political fight. She backed primary challengers against two state senators who blocked her property tax plan in January. The results: one lost decisively, the other is locked in a razor-thin race.
The primaries also delivered a decisive win for Senator Ed Markey over Representative Seth Moulton, extending a pattern of incumbents fending off younger challengers. The outcome could reshape Beacon Hill's balance and test Wu's political influence.
Why it matters
If either tight Senate race flips, it shifts power on Beacon Hill and measures whether mayors can effectively primary state legislators who defy them.

Historical Context
2 moments from history that rhyme with this story — and how they unfolded.
Pressley vs. Capuano (2018)
Boston City Councilor Ayanna Pressley took on 20-year incumbent Mike Capuano in the 7th District primary. Pressley argued Capuano wasn't progressive enough and won 59-41.
Pressley became the first Black woman to represent Massachusetts in Congress.
It showed that incumbents can be defeated in Massachusetts if an outsider energizes new voters around racial and generational themes.
Wu's challengers tried to tap similar dynamics, but most failed this cycle, showing that conditions were not ripe for a repeat.
Markey vs. Kennedy (2020)
Senator Ed Markey, then 74, faced a primary challenge from Joe Kennedy III, a 40-year-old congressman. Kennedy argued for generational change; Markey ran as a progressive with a strong climate record. Markey won by 11 points.
Markey won re-election and went on to co-lead the Green New Deal resolution.
It demonstrated that Massachusetts voters may prefer seniority and policy record over youth in Democratic primaries.
Markey's 2026 victory over Moulton repeats the 2020 pattern, reinforcing that age alone is not a liability in this state.
