1. In an affront to environmental poster boy, Sierra Club leader and mayoral candidate Mike McGinn, the King County Conservation Voters have decided not to endorse either candidate in the mayor's race.

2. In other mayor's race news: I guess Mike doesn't always bike—especially when (as we  reported last night), he can bum a car ride from his opponent, Joe Mallahan.

3. Conservative blogger Angie Vogt has filed a complaint with the Public Disclosure Commission against King County Executive candidate Dow Constantine for a hit piece that the Service Employees International Union, the Washington Education Association, Washington Labor Council AFL-CIO, and the hotel and restaurant employees union among other labor groups ran on Constantine's behalf during the primary.

The $50,000 ad actually focused on Democrat Ross Hunter. (Hunter lost to Constantine, who now faces Republican-backed Susan Hutchison).

The labor coalition, which was called the Working Families Coalition, worked on the hit piece with political consultant Moxie Media, a firm that shares office space with Constantine's consultant, Northwest Passage.

No one has produced evidence of collusion between SEIU and Constantine—it's illegal for groups that run independent expenditures to collaborate with the candidates they're supporting—but the shared offices has got the GOP hopping mad.

Asked if they're now worried that labor might run and independent expenditure against them out of Constantine's campaign consultant's headquarters in the general election, Hutchison spokesman Jordan McCarran said, "Yes. We definitely are."

4. Former Stranger crime newsie Jonah Spangenthal has published his latest scoop in the PI. (This one, published last night, is about a manslaughter case in North Seattle.)

Spangenthal-Lee's was fired from the Stranger two weeks ago.
