THE FATAL FLAWS IN "FIRST-PAST-THE-POST" ELECTORAL SYSTEMS

 

INTRODUCTION:

The First-past-the-post Concept: The term first-past-the-post is synonymous with the terms relative majority and plurality. It refers to the basis on which votes are counted in order to determine who is elected by those votes. Such systems can be used for the filling of a single vacancy, or the filling of a number of vacancies as a group. A first-past-the-post electoral system is one where ballots are not valid unless they have been marked by the voter to indicate the candidate or candidates that the voter wishes to have elected, but no more candidates can be indicated than the number of vacancies to be filled, and the votes are counted as described under "Counting of the Votes" below.

 

The English common law electoral system is a first-past-the-post system, but it allows ballots to indicate votes for fewer candidates than the number to be elected if the voter so chooses, which allows for the traditional plumping by voters. More recent variants of that system are:

(a) the single non-transferable vote, which was used for Japan’s Lower House until it was replaced by a hybrid party-list PR and single-member system (not the same as New Zealand’s Mixed Member Proportional system) at the end of the 20th Century,

(b) the limited vote, and

(c) the now discredited multiple plurality system used for Australian Senate elections from 1903-17, which is referred to below and arbitrarily required
that a valid ballot had to show exactly the same number of votes for candidates as there are vacancies to fill, which thus prevented
plumping.

 

Form of Ballot-papers: Traditionally, ballot-papers for first-past-the-post elections invite the voter to indicate his or her votes by means of marking a cross (X) alongside the name of each of the candidates voted for, but more recent practice in some jurisdictions, such as certain Queensland local government polls and elections in certain Australian unions, has allowed the voter to mark his or her preferences among the candidates in order by marking the numbers 1, 2, 3, 4, 5 etc. against their respective names. In a country like Australia, where the predominant voting system is preferential voting, a benign interpretation of that practice would be that it was instituted to facilitate voting, although a less benign, but possibly more accurate interpretation, would be that it conceals from the less perceptive voters the nature of the system that applies.

 

Counting of the Votes: Where there are multiple vacancies to be filled, the votes on each ballot-paper are counted as being of equal value to each other, even though a voter might have a distinct order of preference among the candidates, as there is no mechanism for such preferences to be given effect to.

 

Candidates are elected consecutively according to who receives the largest number of votes. There is no pre-determined percentage of the overall vote required to be gained before a candidate is elected (hence the description "relative majority"), so a candidate can be elected with a very much smaller percentage of the vote than under any other electoral system if the votes are spread very evenly among the candidates. In elections to fill a single vacancy or elections by the plurality bloc vote referred to below, all the successful candidates can be elected by the votes of very much less than 50% of the voters, with well over 50% of the voters having no effect on the outcome whatsoever, unlike preferential voting, which ensures that a majority, or quota, as the case may be, of voters decides the outcome for each vacancy.

 

First-past-the-post voting systems for filling a single vacancy: These systems, for parliamentary and congressional elections, are now largely confined to parts of the former British Empire such as the United Kingdom, United States of America, Canada, India and Pakistan, although Australia, New Zealand, Eire, South Africa, Malta and Sri Lanka have changed to other systems. These systems are badly flawed because they allow members to be elected in each electorate with well below 50% of the vote, and allow splitting of the vote among candidates of similar views to the benefit of more isolated candidates. Such systems are also used for electing single office-bearers, such as the President of France. The non-transferable nature of the votes cast is the main fault there.

 

Multiple First-past-the-post voting systems: The PRSA History page mentions the quite unfair and unreasonable electoral system used for the election of the Australian Senate from 1903 to 1917. The system also applied, by default, to the first election in South Australia for members of the House of Representatives in 1901. It is variously referred to as a multiple "X" voting, a multiple relative majority, a multiple or bloc first-past-the-post, a plurality at large, a plurality bloc vote, or a multiple plurality system. If an electoral system is not specified in a constitution, the multiple plurality system is unfortunately the common law default system. Under it a voter traditionally marked an "X" against the name of each candidate voted for, with the proviso that the ballot would be invalid if an "X" appeared against the names of more candidates than there were vacancies to be filled. A later, even less democratic variant, used for those 1903-17 Senate elections, arbitrarily specified that the ballot would be invalid if the number of candidates voted for was not equal to the number of vacancies, thus forestalling the traditional option in plurality elections of plumping. The term plurality refers to the largest vote gained by a candidate or candidate, even if that candidate or candidates have failed to gain an absolute majority of votes.

 

The 3 systems used for Senate polls: For Australian Senate elections, that unsatisfactory non-preferential voting system was replaced by a multiple, or bloc, majority-preferential electoral system in 1919, which was in turn replaced by the present quota-preferential system of proportional representation (PR) in 1948. Use of that unfortunate 1919-47 system is now confined to certain municipal polls in the Northern Territory. A routine outcome in Senate elections before 1949 was that candidates of a single party, or point of view, won all of the vacancies for a State, and regularly, once in each of the first five decades of the Senate's existence, for the whole of Australia, as occurred in 1910, in 1917, in 1925, in 1934 and finally in 1943. The multiple plurality system in force prior to 1919 had similar effects, as the 1910 and 1917 examples show, except that it also occasionally filled all vacancies for a State with candidates from the same party that had collectively failed to gain even 50% of the votes for that State.

 

Preferential systems predominating: Preferential systems have generally replaced plurality systems in Australia when the Commonwealth and all States except Queensland made that change around 1920 but, some 90 years later, multiple plurality systems still persist in some quarters. Prominent examples are elections for local government in some rural parts of Queensland, for all of Australia's Anglican Diocesan Synods except Melbourne's, which uses PR, and for the boards of the National Roads and Motorists Association and the Royal Automobile Club of Victoria. These motoring groups compound the flaws of the voting system they use by allowing names of candidates that are retiring directors to be marked on the ballot-paper with an asterisk (*). That has the effect of concentrating establishment votes on those candidates alone. It allows other votes to be dispersed among what is often a large field of candidates. No means are provided for the voters to have their votes pass, in accordance with preferences they indicate, from poorly supported candidates to better supported candidates of their choosing, so that their votes are not wasted.

 

DETAILS OF THE FATAL FLAWS:

Failure to ensure representation of over 50%: The plurality, relative majority, or "first-past-the-post" idea ignores the fact that the candidate or candidates with the largest number of votes does not necessarily gain the support of any predetermined percentage of the votes. All that is required is that the winner's vote total be higher than the rival totals, yet that total might be so low as to leave a majority of voters completely unrepresented by any of the multiple candidates elected. This objection applies even when only one vacancy is to be filled.

 

A majority-preferential voting system (Senate 1919-48) requires that the views of an absolute majority of voters, which is a number exceeding 50%, must be given effect to. A quota-preferential PR system (Senate 1948-) gives effect to well beyond 50% of the votes cast (all but a small percentage of unusable votes).

 

Splitting the votes of a group owing to a proliferation of similar extra candidates: All plurality systems suffer by leaving voters in a quandary if there is a relative abundance of candidates with a particular viewpoint compared with those of opposing viewpoints. A recent example was the first round of the 2002 French presidential election, which resulted in even the strongest-polling candidate, the outgoing President, Jacques Chirac, from the right, gaining less than 20% of the vote. The left was also split, but slightly more so, with the result that the second round, to choose between the two highest-polling candidates, pitted the right against Jean-Marie Le Pen, rather than its realistic opponents, the left. The result was a sham poll, where Chirac took nearly all the votes, owing to the lack of a realistic opponent.

 

Wasting the votes of many of those voting for very strongly supported candidates: Plurality systems being used to fill more than one vacancy as a group, whether by the multiple plurality system described above, by cumulative voting, or by a limited non-transferable vote suffer the flaw that very strongly supported candidates can gain far more votes than they need for election, thus depriving their supporters of the ability to have the magnitude of their vote translated into an appropriate number of seats won, leaving many seats won by very small numbers of votes left after a single, or a few winners have gained most of the votes, with no provision for transferring those votes as happens in the transfer of surplus votes in a quota-preferential PR election.

 

Unfairly forcing some voters to support candidates they oppose: The non-preferential nature of the multiple  plurality system used in the above examples is grossly unfair to voters that find the number of candidates they consider to be acceptable is fewer than  the number of vacancies to be filled. Such voters are required, in order to cast a valid vote, to mark the balance of their vote for candidates they oppose. The multiple plurality system prevents voters indicating the ranking of their preferences for the individual candidates, and forces voters to give them all equal weight. The example in the table below shows how voters' power to give effect to their priorities by marking preferences is suppressed.

 

Plumping: The last flaw above does not apply when only one vacancy is to be filled, nor does it apply to the traditional, common law, form of plurality voting, which allows voters to vote for fewer than the number to be elected, a practice known as "plumping", which allows voters to concentrate their voting power on those they support, rather than being constrained to also vote for those they oppose, in cases where those voters support fewer candidates than the number to be elected. That traditional form was practised in British elections prior to the general abolition of two-member geographical electorates for the UK House of Commons in 1885, as it allowed a crude form of representation of minority opinion where such minorities were large enough.

 

 

HOW AN 80% VOTE WINNER IS DEFEATED BY AN UNFAIR ELECTORAL SYSTEM

 

Multiple first-past-the-post systems prevent voters implementing their priorities, by suppressing notional preference votes.
