San Francisco's Board of Supervisors will take up the issue of ranked-choice voting at Tuesday's meeting.

Under ranked choice, voters name their first, second and third choice of candidates, thereby eliminating the need for a run-off election. Critics say the system is confusing.
 
California Watch reporter Lance Williams says one proposal before the board is to change the system for mayoral elections only.

"The measures that the supervisors are looking at are tweaks or changes aimed at recognizing that the mayor's race is just a bigger deal, I suppose, than the supervisors' race," said Williams. "You want that debate between the top two candidates, as opposed to a big field with no one really engaging on the issues of the day."

Supporters of ranked-choice voting say the new system has not been in place long enough to judge it, and that continuing to make changes only confuses voters more.
