The clock is ticking on a federal lawsuit filed in Spokane by congressional hopeful Clint Didier against an opponent’s volunteer in Grant County, who leads the Washington State Potato Commission. Didier’s lawsuit says Chris Voigt, executive director of the potato group headquartered in Moses Lake, used state-supported resources to push the candidacy of Dan Newhouse, a former director of the state’s Agriculture Department. Didier cites internal emails from the commission in his lawsuit alleging violation of federal and state election laws by Voigt, who also allegedly used a car tied to the commission to pick up and deliver yard signs for Newhouse’s campaign.
