Oregonians will be left with winner-take-all elections for federal and statewide offices, with partial results for Measure 117 showing the “no” vote ahead.

Partial registrations Tuesday showed 59 percent of voters oppose the measure and 41 percent support it.

The vote measure would be called on officials to implement ranked-choice voting by 2028 for elections for president, Congress, governor, secretary of state, attorney general, treasurer and labor commissioner. It also would have allowed cities and counties to implement the voting system for local elections and would have required the Secretary of State’s Office to create a voter education program for the new system.

Under the hierarchical choice system that the measure will establish, voters rank the candidates on the ballot in order of preference. If no candidate receives more than half of the first-place votes, the candidate with the fewest votes is eliminated. Votes for that candidate are then redistributed to the remaining candidates based on subsequent voter preferences. This process continues until one candidate receives the majority of votes.

Supporters of the measure said it would encourage candidates from diverse backgrounds to run for office because they would have fewer concerns about splitting votes with similar candidates. Additionally, they believe ranked choice gives more voters a voice in the election and increases voter engagement.

Opponents of the measure argue that the expanded ballots required for ranked-choice voting create more opportunities for voter error. They also argue that voters will not factor in the result if their top choices are removed during the vote counting process.

The measure received support from many prominent civil rights, labor and civic engagement groups in Oregon, including the American Civil Liberties Union of Oregon, the League of Women Voters and the Portland Urban League.

Wealthy pro-choice supporters from outside Oregon contributed millions of dollars to support the ballot measure. The political action committee supporting Measure 117 has raised $9.4 million as of Tuesday, campaign finance filings show, almost all of it from out-of-state nonprofits.

While no campaign has raised money to oppose Measure 117, a group of county clerks launched a political action committee in August to voice concerns about the measure. Clerks said the new voting system would overburden their offices and cost millions to implement. They also said they weren’t adequately consulted when the Legislature sent the measure to the 2023 ballot.
