Only several hours after Ed Murray decided against running for reelection, the HA Editorial Board decided to endorse Ed Murray not running for reelection. Unlike The Seattle Times or other editorial boards, the HA Editorial Board encourages dissent (at Drinking Liberally last night).
So no, Ed Murray can run if he wants. Nothing has been proven. That said, if he decides to run, or even just in his public statements and defense in court, he should stop the victim blaming. And obviously, fuck him if he did it.
