Over the past couple of decades Ranked Choice Voting (RCV) has been advocated in the U.S. as a substitute for the current first-past-the-post (FPTP) electoral system. While its entrance to the electoral system of the U.S. is yet to be seen, it has found strong support among numerous voter groups, activists and voting theorists. We discuss the proposed voting method in some detail evaluating it in the light of standard social choice criteria of performance. We conclude that while RCV certainly represents an improvement over FPTP in terms of richness of voter input, it falls short of satisfying several important, even essential, conditions for a satisfactory voting method. A modification of and an
alternative to RCV is discussed well.
