How many votes does it take to win?
In a ranked choice election with one winner, a candidate needs at least ½ the votes to win because if one person has more than ½ the votes, we know all the other candidates must have less ½.
The same principle applies to elections with more than one winner.
- If there are two winners, each winner needs at least ⅓ of the votes. If two candidates each have more than ⅓ , then all the other candidates must have less than ⅓, so we know those two must be the top two.
- In a three-seat race, each winner needs ¼ of the votes. If three people each have more than ¼, then all the other candidates must have less than ¼, and we know those three must be the top three.
In general, if a race has N open seats, each winner needs at least 1 / (N + 1) votes to win a seat. With more than one winner, ranked choice voting provides proportional representation so that candidates win seats in rough proportion to their share of the electorate.
What happens if a candidate gets more votes than they need to win?
Then their extra votes go to their supporters' next choices.
Remember: the goal of ranked choice is to give everyone the freedom to vote for who they really like without fear of "wasting" their vote, so once your favorite candidate has enough votes to win, your support will go to your next choice. You don't have to worry about supporting someone who's too popular, just like you don't have to worry about supporting someone who's not popular enough.
