The closing of the polls takes on a whole new meaning in all-mail elections.

A general election ballot needs to be postmarked today, which usually means getting to a post office by the close of its business day.

If the post office is closed, head on down to the King County Elections Division headquarters at 919 S.W. Grady Way in Renton. There’s a drop-off box in the parking lot that will take the ballot envelopes until 8 p.m., the official close of the election. No stamp is necessary.

The elections headquarters in Renton also is an Accessible Voting Center, where those with a disability or who need help filling out a ballot can go for assistance by 8 p.m.

Voters can track their ballots online.

The county will release the first results just after 8 p.m. and then daily at 4:30 p.m., except weekends and the holiday.

The Canvassing Board will certify the results on Nov. 29, with the final results posted at the elections website at noon Nov. 30.

The election in Renton has been highlighted by three contested City Council races and the race to replace Don Jacobson on the Board of Commissioners for Public Hospital District No. 1.

Mayor Denis Law is running unopposed for a second term leading the city.

Once the voting is done, the public can watch the ballot-processing activities in person or on live streaming video from three web cams set up at the elections office.

The election cams display activities in the sorting, opening, and scanning areas of elections headquarters.

The election cams will provide around-the-clock footage of ballot processing on the King County Elections website until the election is certified on Nov. 29.

The public can view the process in person from a viewing loop that circles the main work areas. The loop is open weekdays 8:30 a.m. to 4:30 p.m., with extended hours on Election Days. For more information, call 206-296-VOTE (8683).
