[EM] Mr Hare's system

[Bob Richard [lists]]

Robert Bristow-Johnson asks

How is it different?  Other than multi-winner and the Hare threshold instead of Droop.


By "antithesis" I assume that Richard Lung meant majoritarian as opposed 
to proportional.

IRV (single-winner STV) uses a Droop quota, not a Hare quota. In a 
single-winner election, a Droop quota [1/(S+1)] is a majority. A Hare 
quota [1/S] would mean that complete unanimity is required for any 
candidate to get elected.

But Hare cannot commit to this simple ethic: If more voters mark their ballots preferring Candidate A over Candidate B than the number of voters marking their ballots to the contrary, then Candidate B is not elected.

And this has much to do with Thomas Hare, independent inventor of the Andrae system, as it is called in Scandinavian countries -- but rarely used there. An exception was the Iceland Citizens Convention. And they called in a Scotsman, (Dr James Gilmour) for the STV count.

>Richard, I'm pretty sure that the city council elections in Cambridge Massachusetts are the same Hare STV that FairVote promotes.  Unless these are multiwinner election (I'm not sure about that).  Burlington used exactly the same software to run the election in 2009 and it even has the words "Cambridge" in some of the output files.  I can send them if you want.  Below at bottom I just pasted the text, FYI.
