Diana Jackson, Karim Delgado and Dorian Russell, who campaigned together as the "Seeds of Change" candidates, each won their respective races handily, according to updated tallies Tuesday. The three ran on a shared platform that took direct aim at large corporate tax breaks and unfettered data center development, while elevating housing and affordability as top priorities.

"Loosely calling ourselves the 'Seeds of Change' candidates, we shook hands on our campaigns mutually supporting one another in the fight for affordability and working class values," the bloc said in a joint statement. "Together, the slate found solidarity across differences and a wave of community support more powerful than corporate interests and big donors."

Hillsboro has historically been a corporate-friendly city, home to major employers including Intel, Tokyo Electron America and Epson. Part of the draw has been the city's enterprise-zone program, which waives property taxes for three to five years for qualified capital projects. The city also hosts Hillsboro Airport, the state's second-busiest airfield, where a New York company has sought to build private jet hangars—a proposal that was recently rescinded but is expected to return.

How the city supports its economy became a central dividing line on the campaign trail. Nine candidates competed across the three races, offering different visions for the city's biggest challenges, including data centers, private jet storage, urban growth and rural preservation.

In North Hillsboro, Jackson unseated controversial incumbent Cristian Salgado and defeated candidates Luis Garcia and Sarah Marugg. Updated tallies showed Jackson with 44.83% of the vote, followed by Garcia at 24.66%, Salgado at 16.09% and Marugg at 13.77%. Jackson is a legal assistant at a nonprofit legal firm and has served on Hillsboro's Planning Commission. She was the lone member to abstain from a vote to approve the private jet hangar project at the airport.

Delgado, who owns Beaverton bar 649 and aligns with the Democratic Socialists of America, took 54% of the vote to defeat Ivette Pantoja, a co-founder of Briar Rose School and a Hillsboro School District Board of Director member. Delgado, a longtime community activist who made headlines last October for physically blocking federal immigration agents alongside his wife in their car, will represent south Hillsboro.

"Government can work for you, it just chooses not to. Our work to change that started on election night," Delgado said in a statement.

In west Hillsboro, Russell won with over 50% of the vote as of Tuesday, beating Titonian Wallace at 34.6% and Kimberly Culbertson at 13.44%. Russell was raised in Hillsboro and graduated as valedictorian from Liberty High School in 2013. They now serve as executive director of nonprofit HomePlate Youth Services, which serves people ages 12 to 24 experiencing homelessness.

The progressive shift in Hillsboro mirrors a broader national trend seen on election night, with progressive candidates gaining ground in local races across the country. The Seeds of Change candidates described their victory as a "generational call to action" and vowed to make the city a better place for working families.

"Building solidarity and the power of everyday people will make this government work for the working class," the bloc said. "Our work starts now."
