(Excerpt)
�Voting is a solution to the problem of turning individual preferences for
different outcomes into a single choice by the group as a whole. And
although many procedures have been developed to reduce a list of
alternatives to a desired option, it's surprising how few people realize
that the method of voting they use can significantly impact the outcome of
an election.�
