Finally, any voting system that relies on a particular strategy to produce good results can be replaced by another voting system that executes that strategy on behalf of the voters - so-called declared strategy voting methods. This is a consequence of the [[w:revelation principle]]. It is thus not possible to get around impossibility results by relying on tactical voting.
