Organizers of the three-day event at the Meydenbauer Center in Bellevue appeared to have designed the lineup of speakers in a way that would mask any divisions in party ranks. Democratic gubernatorial hopeful Mark Mullet, a state senator from Issaquah, wasn’t invited to speak at the event, so he chose to skip it all together. Also not invited to speak were state attorney general candidates Nick Brown, a former U.S. attorney, and state Sen. Manka Dhingra, D-Redmond, along with state lands commissioner hopefuls Dave Upthegrove, a member of the King County Council, and state Sen. Kevin Van De Wege, D-Lake Sutherland.
