Honolulu voters face a long ballot with 20 charter amendments, including one that would switch city elections to ranked-choice voting — a neutral but consequential change for candidates and voters alike.

• Mail ballots start arriving this week, with the general election three weeks away.
• One amendment would let voters rank up to five candidates instead of picking just one.
• If nobody clears a majority, votes shift to voters' next choices until someone wins.
• Supporters say it gives people more options and makes it harder for sitting officeholders to coast to re-election.
• The proposals came from a community commission, not the city council, and this charter review happens only once a decade.

Outlook: Even if voters approve ranked-choice voting, it would not take effect until 2032 and would still need action from state lawmakers.
