<DIV style="RIGHT: auto">For those who feel that Bayesian Regret is the be-all-and-end-all measure of voting system quality, that SODA's BR for 100% strategic voters will beat all other systems, including Range/Approval. </DIV></BLOCKQUOTE>
<DIV style="RIGHT: auto"> </DIV>
<DIV style="RIGHT: auto">I guess you will have a hard time arguing this, especially if you have multiple audiences. For instance, whether Range/Approval</DIV>
<DIV style="RIGHT: auto">are even all that great is controversial. But if you're an anti-majoritarian type or think it's unfair/unrealistic to propose that voters</DIV>
<DIV style="RIGHT: auto">are strategic, I guess that SODA looks like a step down.</DIV>
<DIV style="RIGHT: auto"> </DIV>
<DIV style="RIGHT: auto">Didn't you post an example where SODA declined to elect a "weak CW" that you said was actually a good thing? If that's</DIV>
<DIV style="RIGHT: auto">true, I guess some people won't agree with that.</DIV>
<DIV style="RIGHT: auto"> </DIV>
<DIV style="RIGHT: auto">It seems to me that there would be a lot more candidates under SODA. It's pretty hard to spoil the race and there is benefit to</DIV>
<DIV style="RIGHT: auto">be had in receiving some votes. It seems parliamentary that way. How many supporters is too few to consider running?</DIV>
<DIV style="RIGHT: auto"> </DIV>
<DIV style="RIGHT: auto">(I have a simple rule for cutting down the number of candidates. I don't think I've ever mentioned it because I know how </DIV>
<DIV style="RIGHT: auto">idealistic you all are. Just say that the first-preference winner auto-wins if he has more first preferences than second and third</DIV>
<DIV style="RIGHT: auto">place combined. This can make it risky even to compete for third place. The idea is that voters should definitely then realize</DIV>
<DIV style="RIGHT: auto">which candidates are the top three in their race, which could amount to a viability/visibility boost for #3. My rule assumes </DIV>
<DIV style="RIGHT: auto">there's no equal-ranking, but I bet something could be devised for other ballots.)</DIV>
