"This book deals with how uncertainty can be dealt with in models of voting procedures. Using the recent U.S. presidential elections as an example, it demonstrates the extremely large variation in voter opinions that would have resulted in the same observed outcome. Another case discussed to some extent is the vote in German Bundestag that resulted in the transfer of government and parliament from Bonn to Berlin. Also this vote as well as the 2001 British parliamentary elections exhibit a high degree of procedure dependence of outcomes. It turns out that differences in voting outcomes can be explained by differences in the description of consensus states and ways in measuring preferences distances."--Jacket.
