<div dir="ltr" data-setdir="false">I won't reply line by line, because it gets a bit complicated and fiddly. First of all, the bit about honest voters, where you interrupted me mid-sentence! I was replying to what Kristofer said about even an honest vote requiring strategy, and my point that it wasn't particularly complex. When I put <span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;"> "you just pick your least favourite candidate to approve", I meant you pick the candidate you are going to approve who is your least favourite of those who you are going to approve. You pick an approval cut-off and approve everyone above it. Sorry for any confusion. So it's just one decision - your approval cut-off point.</span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;"><br></span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;">As for honest voting - I don't see this as similar to Borda. I think it would only be very rarely that someone would ever mis-order the candidates and approve a candidate they like less than a candidate they didn't approve. I'd say it's less likely than attempting some sort of burial in a ranked-ballot method (including Condorcet).</span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;"><br></span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;">Regarding one-person-one-vote, I think your criticism there is just generally of approval as a method rather than about it failing one-person-one-vote. Someone might prefer a candidate over another but approve both or neither, thus losing the ability to distinguish between them, and this in some cases might prove pivotal to the election result. That this can happen is a valid criticism of approval voting, as this voter was unable to cast their one vote in the most effective way. But I don't think it's enough to say that approval fails one-person-one-vote.</span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;"><br></span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;">In any case, I made that point relative to FPTP. In FPTP you can vote for the "wrong" candidate and not for your favourite of the two frontrunners, and so you can also lose the power of your vote in the same way. So a proponent of FPTP cannot point to any advantage of FPTP over approval in this respect.</span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;"><br></span></span></div><div dir="ltr" data-setdir="false"><span><span style="color: rgb(38, 40, 42); font-family: Helvetica Neue, Helvetica, Arial, sans-serif;">Toby</span></span></div><div><br></div>

We need the system to be more bullet-proof than that. Because we're not talking about impartial judges, these are *partisan* voters that want to promote their political interests by voting.

Like the "Wicked Bible". Because if you meant "just pick your favourite candidate to approve, so one decision", that's of course, no different than FPTP.<br clear="none"><br clear="none">> Approval has advantages outside the usual criterion compliance as well. The results of an approval election are easily published and digested, as with a FPTP election. It's simply a list of votes (approvals) for each candidate. I think this is worth more than it gets credit for. In a Condorcet election, how would the result be published? Every head-to-head separately?<br clear="none"><br clear="none">Yes. If C is the number of candidates (including Combined Write-In), then the number of pairs of candidates is C(C-1)/2. So C(C-1) tallies. If the method is Condorcet-Plurality (or for the legitimate interest of election observers), if we include the tallies of 1st-choice votes, then it's simply C² tallies. 5 candidates, that's 25 tallies. 10 or 12 centimeters of paper tape. Quite doable. For IRV, to make it summable it's 205 tallies, that would take about 3 meters of paper tape to print out. Not doable.<br clear="none"><br clear="none">> Also in a debate versus FPTP, approval is the only method that has no real disadvantages relative to FPTP. FPTP proponents can always fall back on saying their method is simple, much simpler than the proposed alternatives. Well, approval is essentially the same level of simplicity. FPTP passes the rarely passed participation criterion, which approval also does. FPTP proponents don't really have anywhere to go, except to make the spurious claim that approval violates one person, one vote. But this is easily countered.<br clear="none">> <br clear="none"><br clear="none">No it's not. One reason I began my paper with an old (1911) ruling from the North Dakota Supreme Court striking down Bucklin Voting is because one of the concurring opinions had an important simple insight about government elections: We're counting people. Not marks on a ballot. The marks must simply correspond to people.<br clear="none"><br clear="none">Just because the same rules apply to each voter equally does *not* mean that it satisfies One-Person-One-Vote, to count people equally. If, using whatever method you choose or scrutinize, if at the end of the day, M voters preferred Candidate A while N voters preferred Candidate B and Candidate B is elected even though M>N, then those fewer voters for B had cast votes that were somehow more effective than the greater number of voters that preferred A. A method that does not make that simple body count is not guaranteed to satisfy One-Person-One-Vote.<br clear="none"><br clear="none">(And, of course, when there is a cycle, **no** method can satisfy it. But that does not excuse a method for failing to elect the Condorcet Winner when such exists.)<br clear="none"><br clear="none">I am not a FPTP proponent. But this is not a spurious claim.<br clear="none"><br clear="none">If I read you correctly above, then that voter has not been able to express a vote that differentiates their favorite candidate from their 2nd-choice candidate. Now for some voters, they might like both and they don't care which of those two candidates gets elected (just as long as one of them does).<br clear="none"><br clear="none">But I find it very hard to believe that such a voter is the most common. Nearly every voter in every election that I had been aware of *did* actually have a favorite candidate. And if the Approval election turned out to be competitive between their favorite candidate and their 2nd-choice these voters that Approved *both* candidates are going to regret that they Approved their 2nd-choice if that candidate ends up beating their favorite candidate.<br clear="none"><br clear="none">Essentially, for the voter that Approved both A and B (but preferred A to B) and finds out that B wins in a close election with A, they're going to think that their vote didn't count. And it didn't.<br clear="none"><br clear="none">They *have* to be thinking about that as they wonder if they should fill in the oval on their 2nd choice.<br clear="none"><br clear="none">But, of course, if they *don't* Approve their 2nd choice and the race turns out to be between their 2nd choice and the candidate they hate, and the latter candidate wins, they're going to regret not Approving their 2nd choice.<br clear="none"><br clear="none">But in both cases these are tactical considerations that the voter has to make.
