Singleton, a housing advocate with a master's degree in social work, ran as a progressive reformer focused on repairing the county's social safety net. She pulled ahead by 14 percentage points after Brim-Edwards, once considered the favorite, saw several colleagues raise concerns about her leadership and early supporters rescind endorsements in the campaign's final stretch.

"While the outcome was not the one I hoped for, I gave the campaign my best effort and am proud I ran a strong and positive campaign that earned the support of a broad and diverse coalition," Brim-Edwards said in a statement. She added that she intends to keep fighting for the community, saying "a title doesn't make a leader." Brim-Edwards will remain on the board as a commissioner until her term ends in December 2028.

Singleton celebrated in Northeast Portland alongside Bri Williams, who won the District 2 commissioner race. Williams, a current county employee and former Preschool for All staffer with a social work background, led Serena Cruz by nearly 6,000 votes. "I want to build a county where every resident regardless of race, ZIP code, or income has the opportunity to live a healthy, stable, and dignified life," Williams said during her campaign.

In Portland, six incumbent city councilors won reelection, including three democratic socialists, despite a well-funded effort by business-aligned groups to reshape City Hall. In District 3, Steve Novick led, with Tiffany Koyama Lane and Angelita Morillo nearly tied behind him after multiple rounds of ranked-choice counting. Challenger Kellie Torres, backed by Mayor Keith Wilson and the Portland Metro Chamber's political arm, finished a distant fourth.

In District 4, Olivia Clark held the largest lead, followed by Mitch Green and Eric Zimmerman. Eli Arnold, a Portland police officer, trailed in fourth despite a well-financed campaign.

"It wasn't a fluke," Green told supporters at a Democratic Socialists of America election night party at the White Owl Social Club. "The question was: Is our politics durable? I think we know it's durable." Koyama Lane urged the Portland Metro Chamber and Portland Police Association to "pay close attention," adding that "Portlanders are not going back to how it was. Portlanders want councilors who are going to put people before profit."

At the state level, Governor Tina Kotek declared victory over Republican Christine Drazan, holding 53 percent of the vote to Drazan's 44 percent. Drazan acknowledged that news organizations had called the race but stopped short of conceding. "I don't yet know what the coming days will bring," she said. "But I know that my love for Oregon is not measured by the outcome of an election."

Democrats are poised to expand their supermajorities in both chambers of the Oregon Legislature. Michael Welsh led Republican Kevin Mannix by nearly 10 points in House District 21, Hank Sanders pulled ahead in House District 52, and Virginia Stapleton led in Senate District 11, giving Democrats a 19th Senate seat.

In Congress, U.S. Senator Jeff Merkley won reelection with 57 percent of the vote, and Representative Janelle Bynum secured a second term in Oregon's 5th District with 54 percent. Representatives Suzanne Bonamici, Maxine Dexter, Val Hoyle, and Andrea Salinas also won reelection, as did Republican Cliff Bentz in the 2nd District.

Portland voters rejected Measure 26-267, known as "Your 2 Cents PDX," which would have allocated roughly $16 million annually—2 percent of the city's discretionary general fund—to community-led budgeting priorities. Two-thirds of voters opposed the measure. Campaign co-chief petitioner Jim Labbe said proponents would continue working to bring participatory budgeting to Portland. "We're committed to keeping that vision alive and building a path forward," he said.

In Multnomah County Circuit Court races, Diane Sykes won Position 2 with 57 percent of the vote over Laura Maurer Rowan, and Elizabeth Savage won Position 14 with 55 percent over Joe Hagedorn. Sykes, a former public defender who led the Oregon Department of Justice's civil rights division, said she has spent her career "fighting to make sure the law works for everyone, not just those with the resources to navigate it."

The results mark a durable win for progressive candidates in Portland and Multnomah County, even as business groups spent heavily to counter them. The county expects turnout to reach around 70 percent once all ballots are processed.
