Establishes tabulation procedures for ranked choice voting, including rules for eliminating candidates with fewest votes and redistributing those votes to next-ranked choices until a winner is determined.

Requires the Secretary of State to conduct voter education campaigns about ranked choice voting in English and all languages required by state law and the Voting Rights Act of 1965.

Modifies ballot language and instructions to explain ranked choice voting instead of the previous "vote for not more than one" instruction.
