LC- Mark Graves Facebook Share By The Oregonian/OregonLive This year’s May election is a special election, meaning voters are seeing only local candidates -- city councils, school boards, fire districts and the like -- and local ballot measures. It’s too late to mail your ballot to have it counted in time. Instead, take your ballot to a drop box by 8 p.m. Tuesday. Find the one closest to you with this Oregon drop box locator.
