IL SB2004

Authorizes units of local government in Illinois to conduct local primary, general, or special elections using ranked-choice voting, potentially eliminating the need for separate primary or runoff elections

Requires ballots to allow voters to rank at least 5 candidates in single-winner elections, or at least 4 more candidates than seats available in multi-winner elections

Establishes tabulation procedures where candidates are eliminated in rounds until one candidate receives a majority (single-winner) or candidates meet the threshold based on seats available (multi-winner)

Mandates that local governments implementing ranked-choice voting use State Board of Elections-certified voting systems and provide voter education materials

Directs the State Board of Elections to adopt implementation rules, including requirements to release round-by-round results on election night and ballot-level ranking data in machine-readable format upon certification
