Sunday's Oregonian included a story about the Interstate 5 bridge replacement that opened with this intriguing line: "The proposed Columbia River Crossing project is controversial in some quarters, but not among the major candidates running in Oregon's special congressional election." The Oregonian helpfully identified the "major candidates" as Republican Rob Cornilles and Democrats Brad Avakian, Suzanne Bonamici, and Brad Witt.
The Oregonian didn't, however, identify how it selected three of the eight Democrats and one of the five Republicans as being the "major candidates." Perhaps it based its determination on fundraising potential, in which case the major candidates aren't being identified by the media, nor by the voters, but by how well they can court contributions from people who would like their ear in Congress.
Equally possible is that the major candidates are those who support the Columbia River Crossing project, implying that a candidate who is less than gung-ho about spending $3 billion or more on the bridge, light rail, and freeway ramps can't be a major candidate. I think I like that alternative even less than the first.
