Washington State Senator Ed Murray is considering whether to enter the race for Seattle Mayor as a write-in candidate. The election is November 3. See this story.
Last week, the non-partisan primary resulted in the defeat of the incumbent Mayor, Greg Nickels. The names printed on the run-off ballot will be Joe Mallahan and Mike McGinn. The third-place finish by the Mayor was somewhat surprising, and apparently there is support for someone new to enter the race.
