Robson Rotation

Last updated

Robson Rotation is a method of arranging the names of candidates on ballot papers in single transferable vote elections so as to eliminate any influence of the so-called "donkey vote".

Contents

Traditionally, every ballot paper in an election is identical, with the candidates' names and their party groups (if any) in the same order. Within the party or group ticket, the order of their candidates' names is decided by the group. The order of the candidates or groups on the ballot is now usually determined by lot, by the authority running the election, although alphabetical order by surname was formerly used for elections contested by individual candidates.

Having all ballot papers the same can give a slight advantage to the candidate or group listed at the top, or top left, of the ballot paper (depending on the format of the paper), because they will attract a donkey vote. Donkey voters number the preferences on their ballots from left to right and/or top to bottom, purely in the order of the candidates' names and groups on the ballot.

Such voters are a feature of voting systems which require people to express their degree of preference for every candidate or group, by numbering them in preferential order, or have their vote declared invalid. While donkey votes may only form a small percentage of votes cast, they could affect the result in a close contest. The more candidates there are on the ballot paper, the greater the donkey vote is likely to be.

To eliminate any donkey vote advantage, the Robson Rotation system requires ballot papers to be printed in equal-sized batches, with each batch having a different candidate's name appearing at prescribed positions in the party columns on those ballots. As a consequence, there are a number of possible permutations of where candidates' names appear on the various version of the ballot paper. Although that doesn't eliminate donkey voting, it spreads its effect more-or-less equally among all the candidates standing for election.

The method, first used in the Australian state of Tasmania in the 1980 Denison state by-election, is named after Neil Robson, a former Liberal MHA for Bass. [1] [2] It was adopted in Australian Capital Territory elections in 1995. [3]

Kromkowski rotation in Indiana

A similar kind of ballot rotation was introduced in St. Joseph County, Indiana, in the 1970s. The method, used for both printed ballots and lever-operated machine voting, was developed and introduced by Aloysius J. Kromkowski, the head of the election commission, and one of the most popular elected officials (St. Joseph County Clerk until term limited and St. Joseph County Treasurer until term limited). Every precinct had alphabetically shifted ballots. For example, in precinct 1, names on the ballot would be in standard alphabetical order. In precinct 2, names on the ballot would start with the second alphabetically-ordered candidate and the first ordered would be shifted to the bottom, and so on.

It was later codified into law via IC 3-11-14-11.

The two-round system (TRS), also known as runoff voting, second ballot, or ballotage, is a voting method used to elect a single candidate, where voters cast a single vote for their preferred candidate. It generally ensures a majoritarian result, not a simple-plurality result as under first past the post. Under the two-round election system, the election process usually proceeds to a second round only if in the first round no candidate received a simple majority of votes cast, or some other lower prescribed percentage. Under the two-round system, usually only the two candidates who received the most votes in the first round, or only those candidates who received above a prescribed proportion of the votes, are candidates in the second round. Other candidates are excluded from the second round.

<span class="mw-page-title-main">Single transferable vote</span> Proportional representation voting system

The single transferable vote (STV), sometimes known as proportional ranked choice voting (P-RCV), is a multi-winner electoral system in which each voter casts a single vote in the form of a ranked-choice ballot. Voters have the option to rank candidates, and their vote may be transferred according to alternate preferences if their preferred candidate is eliminated or elected with surplus votes, so that their vote is used to elect someone they prefer over others in the running. STV aims to approach proportional representation based on votes cast in the district where it is used, so that each vote is worth about the same as another. Formally, STV satisfies a fairness criterion known as proportionality for solid coalitions.

A Condorcet method is an election method that elects the candidate who wins a majority of the vote in every head-to-head election against each of the other candidates, that is, a candidate preferred by more voters than any others, whenever there is such a candidate. A candidate with this property, the pairwise champion or beats-all winner, is formally called the Condorcet winner. The head-to-head elections need not be done separately; a voter's choice within any given pair can be determined from the ranking.

The electoral system of Australia comprises the laws and processes used for the election of members of the Australian Parliament and is governed primarily by the Commonwealth Electoral Act 1918. The system presently has a number of distinctive features including compulsory enrolment; compulsory voting; majority-preferential instant-runoff voting in single-member seats to elect the lower house, the House of Representatives; and the use of the single transferable vote proportional representation system to elect the upper house, the Senate.

<span class="mw-page-title-main">Donkey vote</span> Type of cast ballot in ranked voting in which candidates are ranked in order of appearance

In electoral systems which use ranked voting, a donkey vote is a cast ballot where the voter ranks the candidates based on the order they appear on the ballot itself. The voter that votes in this manner is referred to as a donkey voter.

A group voting ticket (GVT) is a shortcut for voters in a preferential voting system, where a voter can indicate support for a list of candidates instead of marking preferences for individual candidates. For multi-member electoral divisions with single transferable voting, a group or party registers a GVT before an election with the electoral commission. When a voter selects a group or party above the line on a ballot paper, their vote is distributed according to the registered GVT for that group.

BC-STV is the proposed voting system recommended by the Citizens' Assembly on Electoral Reform in October 2004 for use in British Columbia, and belongs to the single transferable vote family of voting systems. BC-STV was supported by a majority of the voters in a referendum held in 2005 but the government had legislated that it would not be bound by any vote lower than 60 percent in favour. Because of the strong majority support for BC-STV, the government elected to stage a second referendum in 2009, but with increased public funding for information campaigns to better inform the electorate about the differences between the existing and proposed systems. The leadership of both the "yes" side and the "no" side were assigned by the government. The proposal was rejected with 60.9 percent voting against, vs. 39.1 percent in favour, in the 2009 vote.

The single transferable vote (STV) is a proportional representation voting system that elects multiple winners. It is one of several ways of choosing winners from ballots that rank candidates by preference. Under STV, an elector's vote is initially allocated to their most-preferred candidate. Candidates are elected (winners) if their vote tally reaches quota. After this 1st Count, if seats still remain open, surplus votes are transferred from winners to remaining candidates (hopefuls) according to the surplus ballots' next usable back-up preference. if no surplus votes have to be transferred, then the least-popular candidate is eliminated so the vote has chance to be placed on a candidate who can use it.

There are a number of complications and issues surrounding the application and use of single transferable vote proportional representation that form the basis of discussions between its advocates and detractors.

<span class="mw-page-title-main">How-to-vote card</span> Handed-out leaflets in Australian elections with voting instructions

How-to-vote cards (HTV) are small leaflets that are handed out by party supporters during elections in Australia. Voting in the Australian lower house uses a preferential voting system. Voters must rank every candidate on the ballot in order for their vote to count. There are often numerous candidates on the ballot, some with little public profile, so voters may find it difficult to decide on all of them. Parties produce how-to-vote cards ostensibly to help voters. They contain details about the candidate or party as well as instruction how to cast a ranked vote in the order that the party would prefer the voter follow. The flow of preferences can assist the party dispersing the cards directly and indirectly help allied parties.

Instant-runoff voting (IRV) is an electoral system that uses ranked voting. Its purpose is to elect the majority choice in single-member districts in which there are more than two candidates and thus help ensure majority rule. It is a single-winner version of single transferable voting. Formerly the term "instant-runoff voting" was used for what many people now call contingent voting or supplementary vote.

Section 13 of the Constitution of Australia provides for three aspects of the terms of members of the Australian Senate: the timing of elections, the commencement date of their terms and for the Senate to allocate long (six-year) and short (three-year) terms following a double dissolution of the Parliament of Australia. While members of the House of Representatives and territory senators have a maximum three-year term, state senators have a fixed six-year term, subject only to the parliament being dissolved by a double dissolution.

Comparison of electoral systems is the result of comparative politics for electoral systems. Electoral systems are the rules for conducting elections, a main component of which is the algorithm for determining the winner from the ballots cast. This article discusses methods and results of comparing different electoral systems, both those that elect a unique candidate in a 'single-winner' election and those that elect a group of representatives in a multiwinner election.
