Currently, each major party has a separate primary election ballot. Major party's registered voters nominate party's candidates; others' primary ballots include only nonpartisan candidates; all vote for one candidate per office. General election ballot may include multiple candidates per office: unaffiliated, major, minor party candidates. Measure replaces that system for most partisan offices, including many federal (not Presidential), all state, county, city, district offices. Single primary ballot lists all candidates for each office. Voters may vote for any candidate, regardless of voter's or candidate's party affiliation. Only top two candidates per office appear on general election ballot; may be from same party. Primary, general election ballots must contain candidates' party registration/endorsements. Eligible person, regardless of party, may be selected to fill vacancy.
