Vote-by-mail in Oregon

The U.S. state of Oregon established vote-by-mail as the standard mechanism for voting with Ballot Measure 60, a citizen's initiative, in 1998. The measure made Oregon the first state in the United States to conduct its elections exclusively by mail. The measure passed on November 3, 1998, by a margin of 69.4% to 30.6%. Political scientists say Oregon's vote by mail system contributes to its highest-in-the-nation rate of voter turnout, at 61.5% of eligible voters.
