Seattle Mayor Katie Wilson is jumping straight into a family fight inside her own party, lining up behind progressive challengers to two of the city’s most entrenched Democratic lawmakers. Over the weekend, Wilson endorsed Hannah Sabio‑Howell in her bid to unseat State Senate Majority Leader Jamie Pedersen, and Ron Davis in his race against Rep. Gerry Pollet, turning a simmering political feud into a full‑blown storyline as the Aug. 4 primary creeps closer.
Wilson Breaks With Longtime Seattle Incumbents
Wilson confirmed the endorsements in an emailed statement to the Washington State Standard, saying she is done with the unwritten rule that Democrats reflexively back each other once in office. "There is strong pressure for elected officials to endorse fellow incumbents," she wrote, adding that she does not want to treat relationships as a "quid pro quo of governing."
Her move is not limited to one race. Wilson has also endorsed Jaelynn Scott in the 37th District, signaling that she is siding with a slate of upstart, labor‑aligned candidates who want to tug the party further to the left, even if that annoys some of the people she has to work with in Olympia.
National Primaries Help Drive Local Momentum
Wilson’s timing is not an accident. Progressives nationally have been riding a recent burst of primary upsets in New York, where Mayor Zohran Mamdani’s endorsements helped knock out sitting members of Congress. Those results, chronicled by The Guardian, were quickly read by national observers as proof that organizing muscle on the left is still very real.
That wave has emboldened local activists to test long‑serving Democrats at home. In Seattle circles, Wilson’s choices are being folded into that same narrative, with organizers openly comparing the city’s skirmishes to New York’s and treating her endorsement list as a West Coast chapter of the same insurgent playbook.
Labor And The Party Establishment Push Back
Wilson’s endorsements did not land softly. While the King County Democrats and the 43rd District organization have lined up behind Sabio‑Howell, heavyweight labor unions are circling the wagons around Pedersen. In an emailed statement to KUOW, Washington State Labor Council president April Sims said, "Jamie Pedersen is the most progressive Senate Majority Leader we have ever had," warning that losing him could weaken the caucus’s ability to deliver big policy wins.
That tension is where things get tricky for Wilson. Many of the labor groups defending Pedersen are the same institutions that have been crucial to Democratic victories statewide, and they are not thrilled to see the mayor trying to knock out one of their top allies.
What Pedersen's Leadership Means
Pedersen is not just another senator on a nameplate. He serves as the Senate Democratic majority leader and is one of the lead sponsors of the state’s new income tax measure, Senate Bill 6346, a marquee policy win this year. The bill’s official summary on the Washington State Legislature website lists Pedersen among its sponsors.
That record is why Wilson’s endorsement against him lands with extra force. Leadership posts decide what gets a hearing, what gets buried, and how budget fights play out. For both organizers who want sharper policy and unions that care about protecting a reliable deal‑maker, the outcome in Pedersen’s race is about power inside the caucus as much as it is about any single bill.
What To Watch Next
The Aug. 4 primary will send the top two finishers in each race on to November, setting up what could be a bruising general election in seats that have often looked sleepy from the outside. The King County Democrats list already includes Sabio‑Howell in its 2026 endorsements, and campaigns across these districts are hustling to lock down voters and raise money before crunch time.
Expect the usual election‑season blitz to spike through July, with field organizers knocking on doors until their knuckles hurt, union mail hitting mailboxes, and digital ads chasing voters around their social feeds.
For now, Wilson’s endorsements have sharpened a split that has been visible inside Seattle’s Democratic coalition for a while. Her supporters see a mayor trying to line up city policy wins with a generational push for structural change. Some longtime labor leaders and Olympia veterans see a high‑risk move that could sideline one of their strongest players. "It's just astonishing to me," one veteran lawmaker said after the endorsements were announced, a reaction the Washington State Standard reported as emblematic of the shock inside parts of the party.
