text: Negative voting Negative voting allows a vote that expresses the people's disapproval of a candidate. For explanatory purposes, consider a hypothetical voting system that uses negative voting.  In this system, one vote is allowed, with the choice of either for a candidate or against a candidate. Each positive vote adds one to a candidate's overall total, while a negative vote subtracts one, arriving at a net favorability. The candidate with the highest net favorability is the winner. Not only is a negative total possible, but also, a candidate may even be elected with 0 votes if enough negative votes are cast against their opponents.
  Under this implementation, negative voting is no different from a positive voting system, when only two candidates are on the ballot. However, in the case of three or more candidates, each negative vote for a candidate counts positively toward all of the other candidates.
  Consider the following example:
  Three candidates are running for the same seat. Two hypothetical election results are given, contrasting positive and negative voting.  (The illustration assumes perfect polling accuracy and total voter turnout.)
  Election results with positive voting:
  A-voters, with the clear advantage of 40%, logically vote for Candidate A.  B-voters, unconfident of their candidate's chances, split their votes exactly in half, giving both Candidates A and C 15% each.  C-voters, also logically vote for their candidate.  A is the winner with 55%, C at 45%, and B at 0%.
