</blockquote><div><br></div></div><div>Yes, but see my other message about your median-based system. For contentious elections, I prefer the Droop quota. With the Hare quota, the last candidate elected is likely to have about half the support of all the rest.</div>
</div></blockquote><div><br></div><div>I don't think that's necessarily true. It all depends how the voters are divided, how many candidates they approved, and the order in which they are eliminated. If we're electing ten candidates, there's really no reason that, out of the last two-elevenths of the population, exactly 50% will be happy with the last candidate and 50% won't. And I don't think we can decide beforehand that each candidate should represent one-eleventh of the population and one-eleventh of the population should be left unrepresented.</div>
<div><br></div><div>Droop quota is natural in STV because it is the smallest number that can elect no more than the desired number of candidates. With a cardinal method I think Droop is just arbitrary. With one-winner approval voting, even 50% doesn't have any special significance. We just take whoever is the candidate with the most approvals.</div>

<div class="gmail_quote"><div>Suggestions:</div><div>- When a candidate is elected and you need to discard ballots, you could specify a more detailed preference order:</div>
<div>1. Ballots which delegated to that candidate</div><div>2. Ballots which bullet voted that candidate and didn't delegate</div><div>3. Ballots which approved two candidates</div><div>4. Ballots which approved three candidates</div>
<div>5. Ballots which approved four candidates</div><div>6. And so on.</div><div>This eliminates ballots first which approve fewer candidates. You may still have to select randomly within these tiers, but it gives an incentive for people to approve more candidates, which helps the method work better. Right?</div>
</div></blockquote><div><br></div></div><div>Well, up to a point. The problem would be if people approved a "no-hope" candidate, just to puff up the number of approvals on their ballot. This is a form of "Woodall free riding", and it could lead to DH3-type pathologies in the worst case. I'd rather not go there.</div>
<div></div></div></blockquote></div><br><div>Good point. Although if there do happen to be any voters who bullet voted for that candidate but didn't delegate to him, then you should definitely eliminate those first (even before the delegated ones, I think). Once that candidate is elected, ballots which don't approve any other candidates are pretty useless, so you might as well get rid of them.</div>
<div><br></div><div>But after that, I can see why you would be reluctant to incentivize approving more candidates.</div><div><br></div><div>- Andy</div>
