Wrong info on alternate vote / runoff part

There is a wrong info on the part of the text about alternate vote / runoff.
The text say "Under the alternative vote only candidate(s) for whom it is mathematically impossible to win", runoff just remove the guy with less votes to them try get the winner. A guy would just have an mathematically impossible chance to win, if the first candidate had 50% plus 1 votes.
With coombs method you can sort of, remove the candidate with an mathematically impossible chance to win, but this will only happen sometimes. This happens when you remove an candidate with more than 50% of last place votes. But this only happens on this case, and even on this case, you are changing what you consider a good thing, now what matters the most is not being disliked instead of being liked.177.92.128.26 (talk) 19:47, 2 September 2016 (UTC)

Ties

I'm curious - does anyone know what rules are used for ties for second place in the first round? Not that I've ever heard what rules are used in traditional two round systems either. I imagine it is broken randomly, but I could imagine Rank Preference Ballots could be used with an extra round of elimination, letting all 3 stand for the second round and the voters below the three can help break the tie.

Ties are almost impossible since they don't use percentages but absolute votes totals, so it is a one-in-a-million shot which will also happen many other vote system for which there is no safety measure, because it will almost certainly not happen (if there are enough people like 1000 plus). 212.64.56.124 (talk) 16:42, 16 March 2008 (UTC)

Relationship of Contingent, Alternative and IRV

I edited the article to reflect current usage in the U.S. Numerous implemetations and pending legislation of what is called IRV is actually contingent voting rather than the Alternative Vote (eliminate all but the top two, rather than sequentially). For example, Cary, North Carolina calls their method IRV, but has only two rounds of counting, and legislation that passed the Vermont State Senate and is pending in the House that would implement contingent voting for federal offices is also termed "instant runoff voting." I believe the appropriate way to handle this evolution of the term "IRV" is to recognize that the term IRV in common usage is now an umbrella term that encompasses both.

Merge proposal

I think I can handle this myself, but unless there's any comments, I'll try merging these two later tonight: Sri Lankan contingent vote, Supplementary Vote. Tom Ruen (talk) 21:18, 17 February 2008 (UTC)

I did pretty simplistic merge, moving those two into the variations section here. It obviously needs some clean up and re-evaluation. For one the examples don't impress me, being too simplistic with only 4 types of voters with the same first and second choices. Tom Ruen (talk) 02:43, 18 February 2008 (UTC)

Supplementary Vote cleanup

(Transferred from Talk:Supplementary Vote.) Anyone got suggestions on better wording?

Impact on factions and candidates

The Electoral Reform Society criticised SV following the mayoral election in Torbay in October 2005, claiming that 43.5% of second preference votes were ignored as not being given to either of the top two placed candidates, disadvantaging supporters of non-party candidates.

We really need to get the figures for this election on Wikipedia as to my knowledge it's the single biggest example of an SV election taking place with more than three credible candidates (Labour were in tenth place!).

It could be said here, of course, that a cursory look at opinion polls taken during the campaign would give voters an informed idea of which candidates are the front-runners.

Maybe true for the Mayor of London which is high profile, has an electorate of millions and is routinely opinion polled by the media, but for other Mayoral elections the posts's profiles are far far lower for the national & regional media, have smaller electorates and are thus less likely to be polled impartially. So the "informed voter" has to make a far greater effort than in London to work out what is going to be a wasted vote, particularly in a situation like Torbay where a lot of the independent candidates were sitting local or county councillors who were the products of local party turmoil & with notable activist backing and thus potentially credible in a way that the average random independent isn't. I suspect most voters would only see figures on party leaflets, usually in a distorted bar chart with the message "only this candidate can beat that hated candidate".

Later-no-harm for Sri Lankan and Supplementary

There is dispute in another article over whether or not Sri Lankan contingent vote and Supplementary vote also satisfy Later-no-harm criterion. I would assert that they do, given that subsequent choices are only counted when previous choices are eliminated. I would like a consensus to add the Later-no-harm criterion to a new section of satisfied criteria. Tastywheat (talk - contribs) 15:01, 2 October 2008 (UTC)
