We consider the election model in which voters choose a subset from the set of candidates. Both voters and candidates are assumed to possess preferences with separable strict orderings. We investigate a rule satisfying candidate stability, which is the requirement to deter any candidate from strategic withdrawal. We show that a rule satisfies candidate stability if and only if it satisfies independence of the selection for each candidate.
