OR SB1592

Establishes a "top-two" primary system for "voter choice offices" (U.S. Senator, Representative in Congress, Governor, Secretary of State, State Treasurer, Attorney General, state Senator, and state Representative), where all candidates appear on a single ballot regardless of party affiliation and the two highest vote-getters advance to the general election.

Allows any registered elector to vote in primary elections regardless of party affiliation, while political parties may opt out of the unified primary to nominate candidates through their own internal process if they ensure fair participation by affiliated members (but forfeit public funding for doing so).

Permits political parties to endorse candidates, with up to three party endorsements listed on ballots preceded by "Endorsed by:" — parties must adopt endorsement rules ensuring fair participation and file them with the Secretary of State at least 180 days before the election.

Repeals provisions governing precinct committeepersons, county central committees, and state central committees, and removes requirements that candidates be members of a specific party or that appointees to fill legislative vacancies share party affiliation with the prior officeholder.

Becomes operative March 1, 2027, and applies to elections and appointments occurring on or after that date; does not apply to presidential primary elections, which retain existing party-based voting rules.
