 Ranked Choice Voting

Presenter:         Vincent Ferlini, Professor of Mathematics, Keene State College

Abstract:           A voting method has two components: Each voter fills out a ballot that lists two or more
candidates, and then a method is used to evaluate all voters’ ballots in order to determine a
winner.  Ranked Choice Voting refers to the first component – instead of a voter choosing one
candidate, a voter ranks the candidates in order of preference.  There are, however, many
different ways to evaluate ranked ballots.  This talk will give an overview of some of the
well-known methods including the one that has been adopted in Maine along with an
introduction to the analysis of the effectiveness of the methods.

Biography:       Vince receive his Ph.D. in Mathematics from the University of Michigan and has been in the
Keene State Mathematics Department for the past 26 years.  In recent years, mathematicians
have become more interested in exploring such topics as voting systems, fair division
algorithms, apportionment, and gerrymandering issues. Vince’s interest has led to the
establishment of a course at Keene State called Voting, Power, and Apportionment.
