Seattle Mayor Katie Wilson has stepped into several competitive Washington state legislative primaries, endorsing progressive challengers against two long-serving Democratic incumbents — including Senate Majority Leader Jamie Pedersen — in a move that reflects ongoing tensions within the state’s Democratic Party.
Why It Matters
Wilson’s endorsements signal a growing willingness among progressive municipal leaders in Washington to challenge the established legislative hierarchy, even within their own party. The mayor is backing candidates who emphasize tenant rights and grassroots organizing in districts where renters make up a large share of the electorate.
What Happened
Wilson endorsed Hannah Sabio-Howell, a renter and progressive activist, in the race against Pedersen in the 43rd Legislative District — which covers Capitol Hill, the University District, Fremont, Belltown, Montlake, Eastlake, and Laurelhurst. Pedersen has represented the district since his election in 2006 and has held the Senate Majority Leader position since late 2024.
In a separate race, Wilson backed Ron Davis, who helped lead fundraising for her own mayoral campaign, in a challenge against Rep. Gerry Pollet in the 46th District, which encompasses much of north Seattle east of Aurora Avenue. Pollet has held his House seat since 2011. Wilson also endorsed Jaelynn Scott in the 37th District House race, a seat that opened after Democratic Rep. Chipalo Street announced a bid for the state Senate. The 37th District includes Beacon Hill, the Central District, Rainier Valley, Columbia City, and Renton.
Wilson, a first-term mayor and self-described democratic socialist, acknowledged the political risk of crossing fellow incumbents. “There is strong pressure for elected officials to endorse fellow incumbents,” she said. “It’s a way of maintaining relationships, part of the quid pro quo of governing.”
Pollet did not conceal his frustration. “It’s just astonishing to me,” he said. “I have worked hard to support the city’s agenda, including since she became mayor.”
By the Numbers
- Three in four residents in the 43rd District rent their homes, a demographic factor Sabio-Howell’s campaign is expected to center.
- $442,000 in campaign fundraising raised for Wilson’s mayoral run, an effort Davis helped lead.
- 20 years: Pedersen’s tenure in the Legislature, dating to his 2006 election.
- 15 years: Pollet’s time holding his House seat, beginning in 2011.
- 3 races in which Wilson is now actively involved through endorsements.
Zoom Out
The endorsements reflect a pattern seen in several states where progressive city executives have begun prioritizing ideological alignment over institutional loyalty when weighing in on down-ballot primaries. In Washington, intraparty Democratic friction has grown as the legislature navigates difficult budget decisions and new tax policy. Pedersen was a principal architect of the state’s recently enacted income tax on high earners, a measure that drew both support and pushback across Democratic constituencies.
Washington’s labor market has shown mixed signals in 2026, with the state adding 10,600 jobs in May while unemployment held at 5.2 percent — economic conditions that are likely to shape voter priorities heading into legislative primaries. Separately, cost pressures on public institutions, including a 45 percent increase in school district insurance costs tied to sexual abuse settlements, are adding to fiscal strain that state lawmakers will be expected to address.
What’s Next
Washington holds a top-two primary, meaning candidates from all parties compete on a single ballot and the top two vote-getters advance to November regardless of party affiliation. All three districts Wilson is engaged in are heavily Democratic, making the primary effectively the decisive contest.
Pedersen and Pollet are both expected to mount well-funded incumbent defenses. How Wilson’s endorsements translate into organizing support and voter mobilization — particularly among renters and younger progressive voters in urban Seattle neighborhoods — will be closely watched as the primary approaches.
