Not clear what problem with approval they would solve. Unless you are a perfectionist and insist that individuals express nuances of opinion... like which candidate they like better than the other candidate? It was very tedious voting in any of the ranking systems. it's tedious to decide who you like better? who you would prefer if any two candidates are presented? i will say this: even though it is prohibited in the present IRV that Burlington VT has, there is no reason that ties should not be allowed in any ranked ballot. but i would agree it would be tedious to allocate preference points in Range. So, to re-frame my question. What is the fatal flaw with approval? it's essentially like Plurality except you get to mark X on more than one candidate (like you do in multi-seat races). i don't like it for multi-seat (in the state senate for the county i am in, all of our senators are elected from the county at large and there are 6 for my county) i always think i'm hurting a candidate i actively support by voting for another candidate from the same party that i approve of. so then i mark X on only one candidate and, if enough people vote tactically like that, the election works like Plurality. we want an improvement to Plurality because we might like a three or four party system (or 3 parties and viable independents). we want to not have to consider the likelihood of wasting our vote by deciding who to Approve of. we know we approve of the candidate we support, but it is a tactical decision to decide if you approve of a candidate you would normally approve of but is not the candidate that you have actively supported. like what if you're a little old lady and you like and support you representative legislator for re-election. and you support him over any likely candidate from the other party, and it might be close so you wanna feel like you helped him. but your grandson that you cherish and are proud is running as an independent. in fact you gave money to your grandson's campaign. you support your grandson. you don't know if he'll win or not, but you do not want to harm his chances. you also don't want your good ol' incumbent you've always supported. you want to make sure he doesn't lose to the other major party candidate. but you wouldn't mind harming his chances if the race ended up between him and your grandson. is that putting it in an accessible context? so then with Approval voting, for sure this grandma marks X by her grandson's name. but does she or doesn't she Approve her good ol' incumbent? Approval doesn't let you mark it Approve except in the race with my top choice. I'm not interested in subtle flaws that result in imperfect results. I'm interested in flaws that result in big problems such as those we see with plurality and IRV. how 'bout electing the wrong candidate? i mean isn't that the essential flaw? e.g. the flaw with the Electoral College is that sometimes it elects the wrong candidate. it does pretty good when it selects the same winner as the popular vote, but when it disagrees with the popular vote it *never* creates more legitimacy or confidence in the election results. so then why have it? what good is it? it's either ineffective in filtering the popular vote or, when it *is* effective it makes matters worse. such a useful device! with Condorcet you elect the candidate that, from the set of voters who have an opinion, is preferred by a majority of that set over any other candidate that you pick. any winner of an election system that elects a candidate who is not the Condercet winner, has elected someone whom was rejected by the voting majority in favor of the Condorcet winner who wasn't elected. how is that congruent to the principle of democracy? do we have elections and explicitly give it to the candidate

Dear Matthew, you wrote: Suite of complicated systems that strive to reach Condorcet ideals. 1. No regular bloke would ever trust 'em because you can't explain how they work in one or two sentences. Well, here's a very simple Condorcet system which can easily be explained in two sentences: 1. Let voters vote on candidate pairs, successively replacing the loser with a different candidate, in a random order of candidates. 2. As soon as all candidates have been included, the winner of the last pair is declared the overall winner. This system is arguably the earliest example of a Condorcet system. It was devised by Ramon Llull in the 13th century and was successfully used for elections in monastaries.

Re: [EM] Anyone got a good analysis on limitations of approval andrange voting? (long)
This method is also quite hand countable (unlike many other Condorcet methods). That was certainly an important feature in those days :-). It has some randomness in the results (when no Condorcet winner exists). Here's another one. Elect the candidate that wins all others in pairwise comparisons. If there is no such candidate, elect the one that needs least number of additional votes to win all others. (This is of course the famous minmax(margins) that I have promoted quite often.)

Gives a feel for something good enough for their purposes - if there is a CW the CW wins. BUT, if there is a cycle, the best candidate can lose to another cycle member - so better make sure the apparent CW gets compared with every other candidate.

Implementing it on a large scale seems tough and actually voting in it seems tedious. If there are N candidates am I forced to make N-1 decisions? If there is a short circuit way to do the vote then it might be workable. In voting you could start with thinking who you would approve of. Then vote for them, while ignoring the others that you like less. Do any of: Approve them by giving them the same rank. Vote for the best as in FPTP. Rank them to show your preference for better vs lesser. The improvement over approval still seems marginal, especially in large elections and I think the cost for implementing, tabulating and voting is much higher, Agreed the implementing costs - mostly in being able to do this. With the ability you get a big help in some elections and less or little in others (like 0 when only two candidates). Tabulating a ballot gets to be labor when a voter ranks many candidates. Being able to determine winner from the N*N array was an implementing cost, but then easy to do via computer (assuming use of an easy variant of Condorcet). Voters who were happy with FPTP will see no benefit - but no cost once they see they can vote as they have before. Voters who have studied range/score will make two groups: sad to be unable to express the exact size of their likes/dislikes; thankful for the easier decisions involved here. Voters who want to rank higher those they like best will be thankful to get past approval. Dave Ketchum Yours, Jobst Election-Methods mailing list - see http://electorama.com/em for list info
