The latest? Portland architect Stuart Emmons says he'll formally announce a bid against Novick this afternoon. He's been quietly assuring reporters this month that he'd go forward with a race, and has raised more than $20,000 to fuel the bid in less than two months—a fact that suggests he could present a challenge.
Emmons, a longtime proponent of saving Veterans Memorial Coliseum from the wrecking ball, has said he's running on a platform that includes increased access to affordable housing, easing homelessness, and better assisting city schools (which Portland city commissioners have little direct power over). His campaign website offers an overview those issues and more, and touts a list of endorsements that includes former Mayor Tom Potter.
Update: Here's the video Emmons released with his announcement.
