Progressive organizer Katie Wilson, a democratic socialist and longtime transit advocate, has unseated incumbent Bruce Harrell in Seattle’s mayoral race after late-arriving ballots tipped the close contest in her favor. Harrell conceded on Nov. 13, clearing the way for Wilson to take office in January.
Seattle’s all-mail elections once again produced a nail-biter: Bruce Harrell led in early returns, but later-counted ballots pushed Katie Wilson ahead by a narrow margin as turnout in the city climbed to roughly the mid‑50s percent. Harrell conceded on Nov. 13 after updated counts showed Wilson maintaining a small but durable lead.
Wilson, who has not previously held elected office, co-founded and led the Transit Riders Union and ran on an affordability-focused platform that included expanding social housing, boosting transit and childcare access, and exploring new progressive revenue such as a city‑level capital gains tax. She will oversee a municipal government with roughly 13,000 employees and a budget near $9 billion, according to the Associated Press.
The race’s trajectory mirrored a political fight that played out earlier this year over how to fund Seattle’s new social‑housing developer. In a Feb. 11 special election, voters approved Proposition 1A—an “excess compensation” tax on employers for pay above $1 million per employee—by about a 26‑point margin (roughly 63%–37%). Harrell supported the competing Prop. 1B alternative; large employers including Amazon and Microsoft backed the campaign opposing 1A. The Nation’s account links the social‑housing vote to momentum for Wilson’s challenge.
Wilson’s record as an organizer figured into her pitch. She and allied groups helped spearhead minimum‑wage campaigns in nearby cities, including a 2025 Renton initiative that passed with roughly 58% support. Her organization also pushed for employer‑funded transit benefits and broader access to low‑ or no‑cost fares; Washington’s youth ride‑free policy took effect region‑wide in 2022. Earlier, Wilson was part of the “Trump‑Proof Seattle” coalition that successfully urged the City Council to unanimously pass a high‑earner city income tax in 2017 (later invalidated by the courts).
Harrell and allies emphasized experience and a focus on public safety, homelessness and fiscal stability. Labor initially leaned his way—MLK Labor endorsed Harrell in May—before shifting to a dual endorsement with Wilson in September. Harrell also counted support from Gov. Bob Ferguson and business-aligned groups, while a pro‑Harrell PAC amassed more than $1 million. In October, U.S. Rep. Pramila Jayapal publicly endorsed Wilson.
After the August primary—in which Wilson finished first—Harrell moved left on tax policy, sending a business‑tax overhaul (Seattle’s B&O tax) to the November ballot. Voters approved the measure, which raises rates on larger firms while exempting businesses with less than $2 million in annual gross receipts and adding a standard deduction; city materials project it will cut taxes for most small and mid‑sized firms while raising additional revenue from bigger companies.
Personal finances briefly became a flashpoint late in the campaign after Wilson told KUOW that her parents have helped cover childcare costs during the race, an admission her campaign framed as underscoring the city’s steep childcare burden faced by many families.
Seattle voters also delivered other progressive gains citywide. Former federal prosecutor Erika Evans won the City Attorney race with about two‑thirds of the vote, defeating incumbent Ann Davison. Dionne Foster defeated City Council President Sara Nelson for the at‑large Position 9 seat, and Councilmember Alexis Mercedes Rinck won re‑election in Position 8 with a commanding margin. Regionally, progressives swept Burien’s City Council contests, and Burien Mayor Kevin Schilling—who opposed a union‑backed minimum‑wage initiative that passed there in February—lost a closely watched state House race in the 33rd Legislative District.
Taken together, the results cap a year in which Seattle voters repeatedly favored revenue measures tied to housing and social services and elevated candidates promising a more aggressive approach to affordability and public investment.
