This article on election of persons is based on an actual state of affairs. The purpose is to highlight characteristics of the single transferable vote, which have not been dealt with in voting theory. The uninitiated needs to know the following background facts before reading on.
An amendment of the Icelandic constitution is brought about in the following way: After the parliament has adopted an amendment it is dissolved at once and new elections are held. As soon as the new parliament has confirmed the amendment it comes into force.
As a consequence of the financial turmoil in Iceland since 2008 an interest for new procedure for bringing about amendments to the constitution emerged. In 2010 an act was passed on for electing a body for presenting to the parliament a proposition for a new constitution. This body was to be composed of 25 members who were to be elected by single transferable vote, a procedure without precedence in Iceland.
To become a candidate was relatively easy and the number was astonishingly high, 522 in all. Voters were to elect – and rank – up to 25 candidates.
The election of persons on 27 November was a thought promoter. On election day I was present at the largest polling-station in Reykjavik as supervisor. There a Scottish gentleman, who had been invited by the Ministry of Justice in connection with the elections, contacted me. He had been in Iceland on an earlier occasion, i.e. in September, invited by the parliament, then in connection with the handling of the proposed act. He had, as he told me, rewritten the Act for the parliament.
The Scotchman told me the following: This method is in use in Scotland, Ireland, Northern Ireland, Australia, New Zealand and Canada – the British world, he interposed – as well as in Cambridge in Massachusetts, New England. The number of persons to be elected could very well be ten to twelve, seventy being the highest number so far since the method was first applied. Then the voter was to elect – and rank – all the candidates, e.g. 1, 2, etc. all the way up to 69, 70. For the election of Members to the body that shall propose amendments to Iceland´s constitution each voter shall elect – and rank – only 25 candidates.
Here this method will be evaluated with reference to the lessons of the November elections.
But first we would like to introduce a tentative example: One person is to be elected. There are 21 voters. To determine the quota. i.e the number of votes a candidate must have to be elected, a divisor must be set. The divisor equals the number of candidates to be elected plus the number 1. The number of voters, i.e. 21, is then divided by this number, i.e. 21/2 = 10.5.
The quota is found by eliminating the decimal and adding 1. Consequently the quota is 11.
There are 5 candidates: A, B, C, D and E. Eleven voters rank them as follows:
while 10 voters rank them:
The number of votes spent on A equal the quota. The 11 voters who place him at top put B right below him. The ones who place B at top put A at the bottom. With this voting method it does not change anything.
This example is presented to compare single transferable vote with sequential choice in Democracy with Sequential Choice and Fund Voting. In sequential choice B would come out first: He receives 10x4 points for the top position, and 11x3 for position 2, i.e. 73 points in all. A receives 11x4 points for position 1 but none for the bottom position.
Now let us examine what the outcome of such an evaluation by the voters, i.e. wishing to counteract the election of specific candidates, would have been if the method applied at the election of the Constitution Assembly last November had been used. In our example 25 are to be elected, i.e the divisor is 25+1. Let us also assume the following: The number of voters is 100,000. The quota, i.e. the number of votes needed for a candidate to be elected is 3,847. A is placed at the top by 3,900 voters so he is safely in. That would also have been the case even if no other voters had placed him among the 25 ranked. That could also have been the fate of B, who was put at top by 3,850 voters, even if no other voter had included him in their selection. Therefore it is conceivable that 25 candidates are elected, each backed by only a small number but rejected by a vast majority. On the other hand there is a possibility that candidates, who are placed number two or three by most voters, have no chance of being elected because so few of them are placed first in the list.
Of the 25 who were elected for the Constitution Assembly 22 reside in the capital area, 2 in the principal town of Northern Iceland, but only 1 elsewhere. This was the outcome but it is to be presumed that no voter actually wanted things to turn out that way. It is a fact that there is no co-ordination in single transferable vote, it is a coincidence what the final combination will be like. The same is even true of an election of only two persons. That I shall now demonstrate by a near-authentic example.
At a given school the teachers are to elect two teachers for the School Board. The school has premises at two locations, in Ladies' Street – with subjects taught mostly by women – and in Gents' Street with subjects taught mostly by men. Everybody agrees that both places shall be represented – as well as both sexes. In an unbound election of persons or in single transferable vote where every voter places teachers of both sexes and from both locations at top it is not at all sure that the result will match the opinion held by all; it can easily happen that two men will be elected from Gents' Street or two women from Ladies' Street. By applying sequential choice of pairs this can be avoided. A list of all possible combinations will be established and each pair given an identification. The voters rank the pairs and the points will be calculated according to the rules for sequential choice.
This is quite easy when only two shall be elected and there are only two attributes to be taken into consideration. When 25 shall be elected and there is a number of attributes to be taken into consideration, sequential choice is not so easy to apply. The discussion of sequential choice for electing board members in Democracy with Sequential Choice and Fund Voting presents an approach that is without the detriments which are so characteristic of the single transferable vote, as we have seen.
