The secretary of state's office says that 10.6 percent of voters have mailed back their ballots in advance of next Tuesday's election.
In an email sent Monday, spokesman David Ammons said that of the more than 3.9 million ballots that have been sent to Washington state voters, as of Monday, just over 417,000 ballots have been returned.
Washington state is a vote-by-mail state, and voters need to have their ballots postmarked by Nov. 4 in order for their votes to count. Voters also can drop off their ballots at special drop boxes set up around the state.
Voters are being asked to weigh in on two competing gun initiatives, a class size initiative, and congressional, legislative and state Supreme Court races.
