De la manipulation des élections indirectes

This paper is devoted to the analysis of two tiers voting rules. First, one candidate is elected in every jurisdiction and next, an aggregation procedure collects the results from the jurisdictions in order to designate the final winner. It appears that whenever individuals are allowed to change jurisdiction when casting their ballot, it is possible that they can manipulate the result of the election, except when the voting rule is the Priority rule, which assigns a priority order to the candidates.
