The deadline to vote in this election is Tuesday, May 20, and Multnomah County is offering an array of assistance for those who have yet to return their ballots.

Starting Saturday, May 17, Multnomah County Elections will offer some weekend and evening hours for voter assistance at both the Voting Center Express, 600 N.E. Eighth St. in downtown Gresham, and the Multnomah County Duniway-Lovejoy Elections Building. 1040 S.E. Morrison St., Portland.

Temporary hours are: Saturday, May 17, 10 a.m. to 2 p.m.; Monday, May 19, 8 a.m. to 7 p.m.; Tuesday, May 20: 7 a.m. to 8 p.m.

Voters have two choices for returning ballots: By mail (no stamp needed) or taking it to an official county ballot drop site. All 32 drop sites are listed here.

Oregon law requires all elections offices to count any mailed ballot that was postmarked on or before Election Day and also arrives within seven days of Election Day.

People also can track their ballots. Voters can choose to receive ballot alerts and updates in English, Spanish, Russian, Somali, Ukrainian, Vietnamese or Chinese. Text, email or voice alerts will tell voters when their ballots are in the mail and when their voted ballots have been received.

Alerts also indicate whether ballots have been accepted for counting or whether further action is required by the voter. “Accepted Ballot” messages also include a virtual Oregon “I Voted” sticker ready to share on social media.

After the Tuesday deadline, final election results will be certified by Monday, June 16.
