{{main|Independence of clones criterion}}
In order to simplify the issue, academic attention sometimes focuses on a specific kind of strategic nomination: the kind that involves '''clones'''. Clones in this context are candidates between whom every voter is indifferent. They will be tied in every ballot if the voting system allows ties, and will otherwise be consecutive.

It is desirable for the outcome of an election to be essentially unaffected by the addition or removal of clones. Adding or removing a clone candidate should only change the winner if the old winner, the new winner, and the candidate added or removed are all clones of each other. A voting system that satisfies this criterion is considered "independent of clones". Independence of clones was first formulated by [[Nicolaus Tideman]].<ref name="b054">{{cite journal | last=Tideman | first=T.
