Before saying more, I want to say that, in spite of anything that I say below here, SSD is what I want for public elections.
If you've ever participated in an EM poll, the ones where we use all sorts of balloting, then you know that ranking is _lots_ easier than rating. And you know that, especially when there are lots of candidates, Approval is easier than ranking.
In fact, Approval's very easy voting and handcount, in EM polls, will give you a new appreciation for Approval.
In general, I much prefer Approval to RV (in its versions other than Approval). Approval has a simple elegance and beauty that RV doesn't even come close to. In Approval, a sincere vote is essentially the same as a strategic vote.
And, though Approval doesnt give you the kind of expressiveness that Condorcet does, it gives you another kind of expressiveness that rank-balloting cant give: Expressiveness about _how_ good or bad a candidate is. You express that when you vote for him/her or not. You can rank all the candidates in order of preference, but that doesnt tell which ones are disgusting. With Approval you say something that you dont say in a ranking.
Yes, Id rather have SSD, but if its to be a handcount, or there are lots of candidates, and you might not want to ask people to rank that many candidates, then the much easier Approval offers a very good substitute for Condorcets expressiveness, Approvals own kind of expressiveness. Approval would be my 2nd choice then.
RV lets you express fine gradation of preference? Illusory. RVs strategy problem stifles expressiveness more than it provides it.
Now, having said all that about Approval vs. RV, I have to also say that, due to the special situation in our elections, RV would probably give a better result than Approval in our public elections, in spite of Approvals general superiority to RV, and in spite of Approvals great aesthetic superiority to RV.
Ive also talked about RVs much greater familiarity and popularity, and peoples widespread misunderstanding about Approval and 1-person-1-vote. So RV is probably a good public proposal, if SSD turned out to be un-gettable.
By the way, I highly recommend another EM poll. In fact I recommend that we do them regularly. You dont know how you feel about the voting systems and balloting systems until you actually vote them and count them. Take my word for it. In EM polls I substitute Cloneproof SSD for SSD. CSSD is equivalent to BeatpathWinner, the easier, but less obviously-motivated and justified, implementation of CSSD.
When we do a poll, I suggest using rank-balloting, Approval balloting, and ratings. I suggest asking voters to vote sincerely, not strategically in the ratings, since the Approval ballot takes care of strategic voting.
When a definite answer isnt desired, its enough to just get answers from the various methods used. When a definite answer is desired from a multi-mode poll, then I suggest Voters Choice, which weve used in past multi-mode polls.
