Yep, that's the one I was thinking of, too. They got away with it, of course.
AG Rob McKenna let them get away with it. He claimed in an mail to me that he had no authority to investigate vote fraud. I then pointed him the the statute that gave him the authority. Never heard back from him. He was tied at the hip to Gregoire.
Last thing McKenna wanted was a Rossi Governorship because that would mean McKenna would be shut out for at least eight years.
