Today's winner: Mayoral candidate Ed Murray.

UPDATE: As we predicted, the fifth council endorsement is from Jean Godden, whose backing brings Sen. Ed Murray's council support to a five-member council majority. 

In a statement, Godden said McGinn "has not reached out for a one-on-one meeting with me in over two years. We work in the same building. He doesn't have to walk far," and added that Murray has committed to partnering with her to "tackle" gender pay equity at the city.  

"I am assured that Ed will recruit and promote qualified women to positions of authority. Working with Ed, we will address the gender pay gap in City government, then in the city as a whole."

State Sen. Ed Murray plans to announce a fifth endorsement from a Seattle City Council member—one guess, based on a recent Crosscut editorial she co-wrote with Murray endorser Tim Burgess blasting Mayor Mike McGinn's record on gender equity, is that it'll be Jean Godden—this afternoon. (Murray wouldn't tell us who the mystery endorser is.)

Along with council members Tom Rasmussen, Bruce Harrell, Tim Burgess, and Sally Clark, the mystery council member will bring Murray's support on the council to a majority—something the Murray camp says hasn't happened since at least the 1970s. 

McGinn will likely use the council endorsements for his opponent to bolster his claim that Murray is the "establishment" candidate.

However, it's worth noting that several of the achievements McGinn's campaign lists as his top "accomplishments" as mayor were supported by (and, in fact, initiated by in some instances) the so-called establishment council members who are now endorsing his opponent. These include paid sick leave (which passed 8-1), the doubled Families and Education Levy (which passed 9-0), and the First Hill Streetcar (also approved unanimously).
