A week remains before the deadline for Washington's all-mail Nov. 6 election, but hundreds of thousands of people in King County already have put their ballots in the mail or drop boxes.

A week remains before the deadline for Washington’s all-mail Nov. 6 election, but hundreds of thousands of people in King County already have put their ballots in the mail or drop boxes.

Call them the “decided” voters.

About 367,000 ballots had been received by King County Elections as of Tuesday, according to spokeswoman Kim van Ekstrom. That’s more than a third of the roughly 1 million ballots King County expects to be cast.

Snohomish County reported more than 108,000 ballots in hand on Tuesday, and Pierce County had more than 126,000 ballots returned to its elections offices.

King County is projecting 87 percent voter turnout. That’s substantially higher than the statewide projection of 81 percent turnout by Secretary of State Sam Reed, and higher than other nearby counties. Pierce County, for example, is projecting 80 percent. King County’s voter turnout in 2008 was 84 percent.

But van Ekstrom said that, so far, King County’s high turnout prediction is holding up based on the votes arriving by mail.

“We’re a little ahead of where we thought we would be,” she said. The county had 60,000 new voter registrations since June, she added.

Statewide turnout hit a record of nearly 85 percent in the 2008 election.

Ballots must be dropped off or postmarked by Tuesday, Nov. 6, to be valid.
