Sarah Iannarone, a progressive activist and critic of Portland’s government, announced her second campaign for mayor on Tuesday, taking direct aim at the current officeholder, Ted Wheeler, and pledging a new administration that aligns with residents’ liberal sensibilities.

In a 2 minute, 47 second announcement video, Iannarone, said Wheeler had adopted a progressive outlook to win election as mayor and had failed to embody it once in office.

“Mayor Wheeler, the social, economic and environmental issues you pledged to solve in 2016 still plague us today, only now with increased urgency,” Iannarone, 46, said in the video, which shows her riding a bike, taking public transit and participating in rallies.

She continued: “When you ran for mayor you cloaked your campaign in the rhetoric of progressivism. But when the time came to lead, you abandoned those values.”

Iannarone criticized Wheeler’s handling of violent protests, saying he had “ceded the streets of our sanctuary city to armed gangs of bigots.” And she said the mayor has a too-cozy relationship with wealthy campaign donors.

Above all, she said Wheeler was not the leader Portland needs, declaring, “Ted, your time is up.” Portland instead needs “dynamic visionary leadership to unite us and get our city back on track,” she said.

Iannarone is a neighborhood organizer and self-described “everyday antifascist” who has supported nonviolent confrontations with right-wing groups. She is also an advocate for greater bike- and pedestrian-friendly infrastructure and opposes a planned expansion of Interstate 5 through Portland.

In an interview, Iannarone said that if elected she would ease what she described as the city’s harsh treatment of homeless people and pursue major transportation reforms, including the “decommissioning” of I-5.

Iannarone formerly operated the Arleta Library Bakery Cafe and was a leader of First Stop Portland, a Portland State University office that organizes tours of the city’s eco-friendly infrastructure.

She left her job at First Stop in February. Her online resume describes her as a self-employed urban policy consultant and as a faculty member of Wayfinding Academy, a private two-year college in Portland.

Iannarone and Wheeler are familiar opponents. They faced off in the May 2016 primary, in which Wheeler won with 55 percent of the vote to Iannarone’s 12 percent.

Wheeler has said the public should assume he is seeking reelection and his confidants are certain of his intention to run. But he has not officially declared and has not fundraised.
