SEATTLE - Extra-long ballots in three Washington counties mean it will take more than a single stamp for some voters to mail in their votes this year.

The Seattle Times reports that extra initiatives in Snohomish, Whatcom and Douglas counties mean mail-in ballots will take more than one first-class stamp. Ballots, however, can be returned for free in county drop boxes.

In each county, the need for extra postage is noted on both voter material and the return envelope.

Ballots were sent to voters across the state last week. In all other counties the cost to return a ballot is 47 cents, the price of a standard stamp.

The Legislature has considered making return ballots postage-free, a topic that has emerged as a minor issue in this year’s campaign for secretary of state. The state estimated last year that it would cost between $2 million and $3 million per two-year election cycle to put prepaid return postage on every ballot.
