Does RCV help avoid vote splitting and weak plurality?
Spoiler effect has long been a point of contention in close political contests, where a third candidate appears to have drawn first-choice votes away from one candidate in a closely contested race. Ranked-choice voting allows these voters’ full range of preferences reflected in the outcome.
Also, in races with numerous candidates, the winning candidate frequently receives less than 50% of the vote. In such contests, the leading candidate may receive a weak plurality of the vote. Examples from the San Francisco Board of Supervisors elections demonstrate how ranked-choice voting yields a majority or, at least, strong plurality winners in such elections.
