I think I see the intent of Warren's proof. This also generalizes on the tie-breaking situation proposed by Dave Ketchum. I agree this is correct. > You might say that these voting situations are very rare indeed, so > that a single vote *most of the time* does not affect the > outcome. However, "most of the time" is not the same thing as > "always". This suggests that the critique in regard to the meaning of a vote must be a matter of probabilities, and not absolutes. I try to restate it in a more correct form: It is probable that the course and outcome of the election will affect the voter, yet improbable that the voter will affect the course and outcome of the election. This imbalance amounts to a fault in the electoral method, because the individual ought not to be subject to a power over which she (or he) has no corresponding influence. This fault bears upon the human rights of the individual and the moral legitimacy of state power.

In fact, I think that such imperfect methods are necessary > stepping stones to your vision. I agree too, it's necessary that we reach that goal. I also agree that imperfections can be useful as stepping stones. Consider a novel interpretation of this in the situation of a mainstream political party: (a) The party has a maximum of freedom and influence in the election of state officials without infringing on the equal freedom of other parties. (b) The party has a maximum of freedom and influence in the promulgation of state laws, again without infringing on the equal freedom of other parties. (c) The political power and laws of the state that bear upon the party are legitimized in the eyes of the party by corresponding political freedoms (a, b). Insofar as the sovereignty of the state depends upon the loyalty of the party, that sovereignty is secure. (d) The party employs a primary electoral method and system that has decisive effect within its scope. Where the winner of the general election is a party member, that member was previously the winner of the primary. (e) The political freedoms of the party (a, b) are enabled by the decisiveness of the primary electoral method (d), without which the party would have none of those freedoms. (f) The party chooses its own primary electoral method independently of other parties' choices. In freely and independently making this choice, the party is the author of its own liberty (a, b, d, e). The individual has the same goal. To reach this goal, it would be sufficient to follow in the footsteps of the party. Replace "party" by "individual" in the statements above, and then identify what is needed to make each statement true for the individual as it is true for the party. * The crucial thing to note is that (f) requires all electoral methods to be treated equally; the political liberty of the individual depends on the technical liberty of the experts who design, deploy and administer those electoral methods. Where a method is discovered to be imperfect, the experts need not petition or agitate in order to correct the problem; they need only deploy the solution. * Maybe the toughest thing is to reconcile the decisiveness of the primary electoral method (d) with the freedom of the individual to choose her own method (f). Thomas von der Elbe's invention of vote mirroring offers one possible solution. It is based on the translation of votes, a practice that depends upon a detailed knowledge of the differences among the various electoral methods.
