Clone (voting)

In the analysis of voting systems, a clone is an additional candidate who appears as attractive to each voter as an existing candidate. In preference voting systems, voters will rank apparently identical candidates next to each other.

In some systems, the introduction of a clone will divide tend to support between the similar candidates, making it less likely either will be elected. In some other systems, the presence of a clone will tend to reduce support for dissimilar candidates, making it more likely that one (or more) of the similar candidates will be elected. In yet other systems, the introduction of clones will not significantly affect the chances that one of the similar candidates will be elected. There are further systems where the effect of the introduction of clones depends on the distribution of other votes.
