Arizona Proposition 140, officially the Single Primary for All Candidates and Possible RCV General Election Initiative, was an initiated constitutional amendment on the November 5, 2024 ballot in Arizona. The amendment would have replaced partisan primaries with primaries in which all candidates appear on a single ballot. It would have also introduced the use of ranked-choice voting and an electoral threshold of 50% in general elections.
The state of Arizona uses semi-closed partisan primaries, where voters registered with political parties choose their party's candidates for a general election, and independents can participate in one party's primaries. [1] [a] Arizona voters elect two candidates per district to the Arizona House of Representatives, and one to the Arizona Senate. [2]
General elections use a plurality voting system; the candidate – or candidates, for the state house – who receives the highest number of votes is elected to the office. [3]
Under Proposition 140, partisan primaries would have been replaced with a single ballot, with a certain number of candidates advancing to the general election. [3] The state legislature would have needed to pass a bill to determine the specific number of candidates that would have advanced from primaries to general elections. [3] [1]
Candidates in general elections would have needed a majority of the votes to win. [1] If the state legislature opted for a top-two primary system, where two candidates advance to the general election, one candidate would inherently win more than half the votes. If the legislature opted for a top-three, top-four, or top-five primary, where multiple candidates advance to the general election, ranked-choice voting would be used to eliminate candidates until one achieves a majority. [4]
Additionally, Proposition 140 would have amended the state constitution to prohibit denying a citizens rights to vote, hold office, or vote for candidates based on their political affiliation. It would have also banned the use of public funds to administer partisan primaries. [3]
