VoteFair Representation Ranking

  
First -most representative choice is: Farah
Second -most representative choice is: Clifford
Third -most representative choice is: Gordon

VoteFair representation ranking results should be used when more than one choice is to be selected. Why? When there are 100 voters, 51 of them can choose the first winner, so the other 49 voters deserve extra influence in choosing the second winner (instead of letting the 51 voters also choose the second winner). When should representation ranking results be used? When a second candidate is elected to a second equivalent seat on a board of directors, or when an organization pursues a second activity in addition to the most popular activity.

Notice that the choice with the most plurality votes is not necessarily the most popular. Similarly the choice with the fewest plurality votes is not necessarily the least popular.
