The Mail-In Voter Registration deadline is this weekend to register to vote in Washington State’s September 19th Primary. Quoting the Washington Secretary of State’s website,
“The deadline for registering or transferring your voter registration is 30 days before an election. If you register by mail, your application must be postmarked by the 30-day cutoff or it will not become effective until after the election.

If you are not already registered to vote in Washington and you miss the 30-day deadline, you can register in person at your county elections department until 15 days before the election. Contact your County Auditor for assistance and information.”

“You must complete a voter registration form if you are registering for the first time in Washington or if you have moved to a new county. If you have moved within the same county, you may transfer your registration by completing a new form or contacting your County Auditor by mail, email, or phone. There is no registration by political party in Washington state.
