Line 93:
The problem is that such tactical voting would tend to overshoot and give undesired results. This greatly complicates the comparative analysis of voting systems. If tactical voting were to become significant, the perceived "advantages" of a given voting system could turn into disadvantages - and, more surprisingly, vice versa.
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.
