Thus, ethical action should be voluntary -- not forced by legal constraints. It should be enforced through electoral action -- voting against unethical parties (any party refusing to pledge not to abuse the system).
Yes, I have come much closer to this position. There are still a couple of things that ought to be cleaned up. First, lets use zero-based instead of 1-based Borda counts. Second, lets fix the system so that elimination works more or less as intended, that is elimination should not get stronger for each faction the more you eliminate.
Back to my expressiveness example. Instead of using the lowest count for each eliminated faction, you can reverse the direction. For ranked factions use counts:
3, 2, 1, 0
And for eliminated factions use counts:
_, 1, 0, -1 (if you want more severe use _, -2, -1, 0; or _, -3, -2, -1)
So the scores are:
3, 2, 1, 0 (none eliminated)
3, 2, 1, -1 (one eliminated, subtract one point last faction)
3, 2, 0, -1 (two eliminated, subtract one point from each of the two factions)
3, 1, 0, -1 (three eliminated, subtract one point from all three)
Now the counts for the eliminated factions would be applied evenly across all eliminated factions. This means that when you eliminate faction A, it has the same effect for faction A as if you eliminate faction A and B. In other words it allows the expressiveness of elimination, without the trick that makes your vote stronger by eliminating all you can. Its a small fix, but it makes elimination work in a way that is much closer to our intuition about it.
