10050.

 (a) A total of not more than 12 cities and counties may conduct a local election using ranked voting in which voters rank the candidates for office in order of preference. The 12 cities and counties shall consist of the following:

(1) Not more than four cities or counties authorized under this subdivision shall be located in the northern California counties of Alameda, Alpine, Amador, Butte, Calaveras, Colusa, Contra Costa, Del Norte, El Dorado, Glenn, Humboldt, Lake, Lassen, Marin, Mendocino, Modoc, Napa, Nevada, Placer, Plumas, Sacramento, San Francisco, San Mateo, Santa Clara, Santa Cruz, Shasta, Sierra, Siskiyou, Solano, Sonoma, Sutter, Tehama, Trinity, Yolo, and Yuba.

(2) Not more than four cities or counties authorized under this subdivision shall be located in the central California counties of Fresno, Inyo, Kern, Kings, Madera, Mariposa, Merced, Mono, Monterey, San Benito, San Joaquin, San Luis Obispo, Stanislaus, Tulare, and Tuolumne.

(3) Not more than four cities or counties authorized under this subdivision shall be located in the southern California counties of Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura.

(b) If in a single election the voters of two or more cities and counties approve the use of ranked voting, and if the authorization of one or more of these cities or counties would exceed the maximum number allowed to be authorized under subdivision (a), then all of those cities and counties shall be authorized.

(c) Ranked voting elections may be used for single-winner elections, such as Mayor or City Attorney, or for elections that elect multiple candidates to office, such as city council. Ranked voting elections are tabulated in rounds as specified in Section 10058 for single-winner elections and Section 10059 for multiple-winner elections. General provisions for both single-winner elections and multiple-winner elections are specified in this chapter.

(d) Only general law counties and general law cities may use ranked voting pursuant to this chapter. A charter city or charter county may use ranked voting if authorized by its charter or other provisions of law.

10051.

 A city or county shall submit a written request to the Secretary of State for authorization to use ranked voting in a local election upon certification of a ballot measure or the adoption or certification of the passage of an initiative ordinance pursuant to Section 10054. The Secretary of State shall approve each request in the order of its receipt until the maximum number of cities and counties, as specified in Section 10050, has been authorized to use ranked voting.

10052.

 (a) A city or county may not conduct a local election using ranked voting unless that election is conducted on a voting system that is capable of conducting the election using ranked voting and that voting system has been approved by the Secretary of State pursuant to Division 19 (commencing with Section 19001), or by another procedure that has been approved by the Secretary of State, which at minimum includes detailed specifications for counting, auditing, and reporting of results.

(b) If the Secretary of State withdraws approval of a voting system, pursuant to Section 19222, that was either intended to be used, or was used, by a city or county authorized by this chapter to conduct a ranked voting election, the city or county shall use alternative equipment or procedures approved by the Secretary of State when conducting subsequent ranked voting elections. In the absence of an approved method for conducting a ranked voting election, the authority of that city or county to conduct a ranked voting election shall be temporarily suspended until the Secretary of State approves the use of equipment or procedures to conduct ranked voting elections. A city or county affected by this subdivision shall still be considered one of the cities and counties references referenced in Section 10050.

10053.

 The following definitions apply for purposes of this chapter:

(a) “Continuing ballot” means a ballot that counts toward some candidate.

(b) “Continuing candidate” means a qualified candidate that has not been elected or eliminated.

(c) “Majority of votes” means more than 50 percent of the votes from continuing ballots.

(d) “Qualified candidate” means a candidate listed on the ballot for this election or a write-in candidate qualified for participation in this election.

(e) “Ranked voting” means an election method in which voters rank the candidates for office in order of preference, and the ballots are counted in rounds that, in the case of a single-winner election, simulate a series of runoffs until only two candidates remain, with the one having the greater number of votes being declared the winner, or in the case of multiple-winner elections, until all seats to be elected have been filled.

(f) “Ranking” for a candidate on a voter’s ballot is the number assigned to that candidate by the voter to express his or her preference for that candidate, with the “highest ranking” being the one with the lowest numerical value for a qualified candidate, in which a first choice ranking indicates a greater preference for a candidate than a second choice ranking, and “highest continuing ranking” for a candidate on a voter’s ballot is the ranking with the lowest numerical value for a continuing candidate. The “highest ranking” and “highest continuing ranking” are those rankings already advanced past blank choices or marks for unqualified write-in candidates as specified in subdivision (b) of Section 10056 and subdivision (a) of Section 10057.

10054.

 (a) A voting method authorized by this chapter may be adopted by either of the following means:

(1) By approval of a ballot measure submitted to the voters by the governing body of the city or county at an election pursuant to Division 9 (commencing with Section 9000).

(2) By initiative ordinance adopted pursuant to Division 9 (commencing with Section 9000).

10055.

 A city or county using ranked voting in a local election shall conduct a voter education and outreach campaign to familiarize voters with ranked voting in English and in every language in which a ballot is made available to voters in that city or county. The voter education and outreach campaign shall include public service announcements on radio or television or in the print media that are disseminated consistently with the language assistance requirements of the federal Voting Rights Act of 1965 (42 U.S.C. Sec. 1973aa-1a).

10056.

 (a) A ranked voting ballot shall allow voters to rank as many choices as there are candidates. If the voting equipment cannot feasibly accommodate a number of rankings on the ballot equal to the number of candidates, the elections official may limit the number of choices a voter may rank to the maximum number allowed by the equipment. This limit shall never be less than three.

(b) The ballot shall not interfere with a voter’s ability to rank at least two write-in candidates. For the purposes of this section, a mark for an unqualified write-in candidate shall not be considered a mark for a candidate.

10057.

 (a) In the first or any round, if a ballot reaches a ranking with no candidate indicated, that ballot shall immediately be advanced to the next ranking. If a mark for an unqualified write-in candidate as described in subdivision (b) of Section 10056, that ballot shall be advanced to the next ranking.

(b) If two or more candidates tie for the smallest number of votes, the candidate to eliminate shall be chosen by lot in a manner similar to that described by subdivision (a) of Section 15651, except that subdivision (b) of Section 15651 shall not apply, and the candidate chosen by lot shall be eliminated.

(c) After each round, any ballot that is not continuing is an undervote, overvote, or exhausted ballot, pursuant to this subdivision. A ballot that has no candidates indicated at any ranking shall be declared an “undervote.” If a ballot reaches a ranking with more than one candidate indicated, that ballot shall immediately be declared an “overvote.” If a ballot cannot be advanced because no further candidates are ranked on that ballot, that ballot shall immediately be declared “exhausted.” A ballot that has been declared an undervote, overvote, or exhausted shall remain so and shall not count toward any candidate in that round or in subsequent rounds.

10058.

 Ranked voting pursuant to Section 10050 for an election to elect a single candidate to office shall be known as “instant runoff voting” and shall be conducted in the following manner:

(a) The ballots shall be counted in rounds pursuant to the following order:

(1) In the first round, every ballot shall count as a vote towards the candidate indicated by the highest continuing ranking on that ballot.

(2) After every round, if exactly two candidates remain, the candidate receiving the greater number of votes from the continuing ballots shall be declared elected. If both candidates received the same number of votes from the continuing ballots, the tie shall be resolved by lot.

(3) If more than two candidates remain, the candidate receiving the smallest number of votes shall be eliminated, and every ballot counting toward that candidate shall be advanced to the next-ranked continuing candidate on the ballot. If there is a tie between two or more candidates for the smallest number of votes, the tie shall be resolved by lot. All the ballots shall be counted again in a new round.

(b) During the elimination stage of any round, if a candidate has more votes than the combined vote total of all candidates with fewer votes, but less than a majority of votes, all the candidates with fewer votes than this candidate shall may be eliminated simultaneously, and those ballots advanced to the next-ranked continuing candidate. If two or more sets of candidates meet this criterion, the provisions of this subdivision apply to the largest set. For purposes of this subdivision, “sets “set of candidates” means ____ a continuing candidate and all other continuing candidates with the same or fewer votes than that candidate.

(c) Notwithstanding the provisions of this section, if a voting system cannot feasibly continue the count until only two candidates remain, the system may terminate the count when a candidate receives a majority of votes from the continuing ballots, and the candidate who received the majority of votes shall be declared elected.

10059.

 Ranked voting pursuant to Section 10050 for an election to elect two or more candidates to office shall be known as “choice voting” and shall be conducted in the following manner:

(a) The minimum threshold of votes required for election shall be determined by dividing the total number of votes cast for that office, excluding undervotes as defined in Section 10057, by one more than the number of offices to be filled and then adding one vote, and then disregarding any fraction, as shown in the following formula:

The total number of votes cast, excluding undervotes as defined in Section 10057, divided by the sum of one plus the number of offices to be filled, plus one, disregarding any fraction, equals the minimum threshold of votes necessary to be elected.

(b) All ballots are counted and each ballot is allocated as a vote to the candidate receiving the highest ranking.

(c) Each candidate that receives the minimum threshold of votes necessary to be elected shall be declared elected.

(d) If a candidate on the first count has a number of highest ranking votes exactly equal to the minimum number of votes required for election, that candidate is declared elected, and the counted ballots indicating that candidate as a highest ranking are put aside and the other rankings recorded on the ballots are not examined.

(e) If a candidate on the first count gains more than the minimum number of votes required for election, the candidate is declared elected, and the number of votes in excess of the number of votes required for election (the surplus) is recorded. All of the elected candidate’s ballots are then reexamined and assigned to candidates not yet elected according to the highest continuing ranking on the ballots of those who gave a first preference vote to the elected candidate. These votes are allocated according to a “transfer value.” The formula for the transfer value is:

Surplus votes cast for the elected candidate, divided by total number of votes received by the elected candidate, calculated out to four decimal places using “rounding to nearest” equals the to five decimal places, with any remainder discarded, equals the transfer value.

(f) If two or more candidates on the first count gain more than the minimum number of votes required for election, all of those candidates are declared elected. Each of the ballots of the candidate with the largest number of highest ranking votes will be reexamined first and assigned (at the transfer value) to candidates not yet elected according to the next highest continuing ranking marked on that ballot. The ballots of the other elected candidates will then be reexamined and their surpluses distributed in order according to the number of highest ranking votes each candidate received in accordance with paragraph (2) of subdivision (i).

(g) (1) If a candidate reaches more than the minimum number of votes required for election as the consequence of a transfer of votes from an elected candidate, the number of votes in excess of the number of votes required for election shall be transferred to other continuing candidates. This transfer will be to the next highest continuing ranking shown on each of this candidate’s ballots. These ballots now include (A) ballots indicating this candidate as the highest ranking, and (B) the ballots transferred to the candidate from one or more elected candidates. The transfer value for the ballots on which the candidate was indicated by the highest ranking is the same as the transfer value defined in subdivision (e).

(2) The transfer value for each ballot transferred to the candidate from one or more previously elected candidates shall be the surplus votes cast for the elected candidate divided by the total number of votes received by the elected candidate multiplied by the previous transfer value of the ballot received by that candidate, as shown in the following formula:

The surplus votes cast for the elected candidate, divided by the total number of votes received by the elected candidate, multiplied by the previous transfer value of the ballot received by that candidate, calculated out to four decimal places using “rounding to nearest.”

(h) If no candidate has a number of votes equal to or greater than the minimum number of votes required for election, either on the first count or as a consequence of a redistribution of surplus votes from a previously elected candidate, the candidate with the smallest number of votes is eliminated. All of the eliminated candidate’s ballots, both ballots indicating that candidate as the highest ranking and any ballots transferred from other candidates, are transferred to the next highest continuing ranking on the eliminated candidate’s ballots. The ballots in which the eliminated candidate was indicated by the highest ranking are transferred to the candidate indicated by the next highest continuing ranking on that ballot at full value. Ballots received from previously elected or previously eliminated candidates are transferred at the transfer value at which the ballots were received.

(i) Tabulation of votes shall continue in the following sequence:

(1) Determine whether a candidate received more votes than the sum of the combined vote total of all candidates who received fewer votes than that candidate and the combined total of all surplus votes not yet redistributed. If this is the case, all candidates with fewer votes than this candidate shall may be eliminated simultaneously according to the procedure specified in paragraph (3), so long as the number of elected and remaining continuing candidates is greater than, or equal to, the number of candidates to be elected. If two or more sets of candidates meet this criterion, the provisions of this paragraph apply to the largest set. For the purposes of this paragraph, “sets “set of candidates” means ____ a continuing candidate and all other continuing candidates with the same or fewer voters than that candidate.

(2) The surplus votes of elected candidates shall be redistributed until no more candidates receive the minimum threshold of votes required for election. The surplus votes of the newly elected candidate with the greatest surplus will be distributed first, and the surpluses of the other newly elected candidates will then be distributed in order according to the number of surplus votes of each elected candidate awaiting transfer of surplus votes.

(3) Candidates are eliminated as specified in subdivision (h), and the votes of eliminated candidates are redistributed until another candidate receives the minimum threshold of votes required for election.

(4) When the number of elected and continuing candidates is equal to the number of candidates to be elected, all of the continuing candidates are declared elected even though they may not have reached the minimum threshold of votes required for election.

(j) A tie between two or more candidates for fewest votes, as specified in subdivision (h), shall be resolved by lot, and the candidate chosen by lot shall be eliminated. A tie between two or more candidates for the number of highest ranking votes received, as specified in subdivision (f), or the most surplus votes, as specified in paragraph (2) of subdivision (i), shall be resolved by lot, and the candidate chosen by lot shall be the first to have his or her surplus votes transferred.

10060.

 (a) The instructions to the voters for an election that uses ranked voting shall read substantially as follows:

“To vote in this election, indicate by selecting or marking a ‘1’ in the voting square to the right of your first choice, a ‘2’ in the voting square to the right of your second choice, a ‘3’ in the voting square to the right of your third choice, and so on. Do not give the same number to more than one candidate. You may rank as many or as few of the candidates as you choose, up to the limit specified, if any. Your second choice will not hurt your first choice, your third choice will not hurt your first two choices, and so on.

“You may include one or more qualified write-in candidates in your rankings by writing each person’s name in one of the blank spaces provided for that purpose after the names of the other candidates for the same office, and then writing the desired ranking in the voting square to the right of that name.”

(b) The instructions may be modified as appropriate for the specific voting equipment used, as long as the intent of this chapter is preserved.

10061.

 (a) As soon as possible after the close of polls of a ranked voting election, the local elections official shall post ballot image reports on the official Internet Web site for the city or county. If a city or county does not have an official Internet Web site, the local elections official shall make the ballot image reports available to the public by other means as soon as possible after the close of polls and notice of the availability of the ballot image reports shall be prominently displayed in an appropriate public location of the city city’s or county’s election division. The “ballot image report” for an election means a report that lists, for each ballot, the candidate or candidates indicated at each ranking, the precinct of the ballot, and whether the ballot was cast by mail. In the report, the ballots shall be listed in an order that does not permit the order in which they were cast in each precinct to be reconstructed.

(b) The local elections official shall also make a summary report and a comprehensive report available to the public after each ranked voting election. The “summary report” for a race means a report that lists the candidate vote totals in each round, along with the cumulative numbers of undervotes, overvotes, and exhausted ballots in each round.

(c) The “comprehensive report” for a race means a report that categorizes the numbers in the summary report by precinct. The report shall list, for each round, the number of ballots cast in each precinct that count as votes for each candidate in that round, that have been declared undervotes, that have been declared overvotes up to that point, and that have been declared exhausted up to that point.

(d) The local elections official shall make preliminary versions of the summary report and ballot image report available as soon as possible after the commencement of the official canvass of the vote pursuant to Section 15301 and prior to the 1 percent manual tally pursuant to Section 15360. The summary report, ballot image report, comprehensive report, and preliminary versions of the summary report and ballot image report shall be made available to the public during the canvass on the Internet and by other means. The ballot image report and preliminary versions of the ballot image report shall be made available in a plain text electronic format.

10062.

 (a) A city or county that conducts an election using ranked voting pursuant to this chapter shall prepare a report, in a format specified by the Legislative Analyst, describing the success of the conduct of the election, including, but not limited to, any statistics on the cost to conduct the election, voter turnout, and the number of ballots that were not counted and the reason those ballots were rejected. Whenever possible, the report shall compare the election using ranked voting to similar elections that were not conducted as ranked voting elections. The report shall also include feedback received by the city or county about voter satisfaction with ranked voting and any problems that became known to the city or county during the election or canvass.

(b) The report required by subdivision (a) shall be submitted to the Legislative Analyst by a time specified by the Legislative Analyst.

(c) Within six months of its receipt of the reports required by this section, the Legislative Analyst shall, based on those reports, report to the Legislature regarding the success of using ranked voting in general law cities and counties and shall make recommendations to the Legislature about whether the Legislature should authorize the expansion of ranked voting in general law cities and counties, and, if so, any procedures that the Legislature should adopt or change to improve the conduct of elections conducted using ranked voting.
