2019 WA Senate Election – Ballot Paper and Preferences Analysis

This is my latest look back at how the Senate’s new electoral system worked at the 2019 election, how voters completed their ballot papers, what preference flows were produced, and what was the influence of how-to-vote material.

In summary, the smaller a party’s vote, the more likely its preferences will scatter widely or exhaust. The more that a party has an identifiable position on the left-right spectrum, the more likely that its preferences will flow in a particular direction.

And the more obvious a party’s how-to-vote recommendation, and the more how-to-votes are handed out, the more likely that voters will follow or guess the recommendation.Read More »2019 WA Senate Election – Ballot Paper and Preferences Analysis

Is Increasing the Membership Requirement to Register Political Parties Justified?

The government’s proposed changes to party registration rules, released last week, will increase the number of members required to register a political party from 500 to 1,500. Understandably this proposal has attracted criticism, especially from the small parties that will now have to recruit more members.

I posted on Thursday about this and other proposed changes to the Commonwealth Electoral Act.

Is this just an attack on small parties, or is it a justifiable attempt to make Senate ballot papers easier for voters to read and understand, and for the Australian Electoral Commission (AEC) to print and count?Read More »Is Increasing the Membership Requirement to Register Political Parties Justified?

2019 SA Senate Election Part 2 – the Preference Distribution

Part 1 of my post on the 2019 SA Senate election analysed how voters completed their ballot papers under the new Senate system, how preferences flowed between parties and what was the impact of how-to-votes.

This post will be more descriptive in summarising the formal distribution of preferences. It highlights major exclusions and distributions during the count and comments on differences with how the count might have unfolded had the abolished group voting ticket system still been in place.

2019 SA Senate Election – Ballot Paper and Preferences Analysis (Part 1)

This is my latest (and much delayed) post looking at the Senate’s new electoral system, how it worked at 2019 election, how voters completed their ballot papers, and what was the influence of how-to-vote material.

This post on South Australian is my first on a six-member Senate contest. The two previous posts in this series, on the ACT Senate race and the Northern Territory Senate race, dealt with elections for two Senators and were two-party preferred races.

At the start of 2020 I published two other posts with broad overviews of the 2019 result. The first looked at the breakdown of above and below the line voting and the number of preference completed. The second looked at measures of performance, why the new system produced different results to past Senate elections. In particular, it compared the 2019 result with the 2013 half-Senate election, the last conducted using the now abolished group voting tickets.

Part 2 of this post tracks the formal distribution of preferences for the South Australian Senate. The Part 1 post below provides a more detailed analysis of preferences based on examining the electronic ballot papers.

Filling all the BTL Squares – Incidence at the 2019 SA Senate Election

As promised, here’s one of my occasional Graph of the Day posts on something I’m currently researching.

How many people voting below-the-line (BTL) on Senate ballot papers go on to fill in all the squares? Here’s the answer in a graph using South Australian Senate data from the 2019 Federal election.Read More »Filling all the BTL Squares – Incidence at the 2019 SA Senate Election

2019 ACT Senate Election – Analysis of Preferences

This is the second in my series looking at how the Senate’s new electoral system worked. This post is on the ACT, which like the Northern Territory, has only two Senators. Both Senators face the electorate every three years in terms tied to the term of the House of Representatives. (See my previous post on the Northern Territory for an explanation of territory Senators.)

(My earlier overall analysis of Senate voting can be found in this post.)

Like the Northern Territory, the ACT has returned the same party representation at every election since 1975. Every ACT Senate election has elected one Labor and one Liberal Senator. With the quota for election set at 33.3% quota, support for a major party would have to be well short of this vote to miss out on a seat.

(Hint – if you are viewing this post on a mobile phone, the tables look much better if you turn your phone sideways.)

2019 Northern Territory Senate Election – Results and Preference Flows

Summary of findings

  • Preferences were not distributed in the NT, the lead Labor and CLP candidates declared elected on the first count.
  • At 19.5% the Northern Territory had the highest rate of voters going beyond six preferences above the line, four times the national average. This was helped by there being only nine ballot paper groups in the NT.
  • 77.7% of Green preferences reached Labor, but not by following the Green how-to-vote. Of all Green votes, 45.5% went to Labor as a second preference, another 21.3% at the third preference after giving a suggested second preference for HEMP.
  • United Australia Party (UAP) preferences favoured Labor, against the party’s how-to-vote recommendation for the CLP, largely because one in five UAP above-the-line votes were donkey votes.
  • On how-to-vote concordance, 16.0% of Labor voters followed the how-to-vote exactly compared to 10.3% for the CLP and 10.2% of the Greens. Green concordance rates were lowered by the 2nd preference being given to HEMP rather than Labor.

2019 Senate Election – Above and Below the Line Vote Breakdown

The 2019 Senate election was the second conducted under changes introduced in 2016. The changes continued to use proportional representation by single transferable vote, and retained the divided ballot paper in use since 1984, and . A thick horizontal line continues to divide the ballot paper into two voting options, ‘above the line’ (ATL) for parties and groups, or ‘below the line’ (BTL) for candidates.

The changes abandoned full preferential voting in favour of partial preferential voting, and ended party control over between-party preferences.

Before the changes, voters could only mark a single square when voting ATL, the ballot paper imputed to have the chosen party’s full list of preferences as registered with the Electoral Commission.

The new system abolished the tickets and allowed ATL voters to give second and further preferences, ballot paper instructions suggesting at least six preferences. Above the line votes continued to give parties and groups control over preferences between their own candidates, but ended party control over preferences to other parties and candidates.

Previously a BTL vote required a voter to mark preferences for all candidates on the ballot paper. Under the new system, ballot paper instructions stated that BTL voters should mark at least 12 preferences.

In an earlier post I went into the political impact of these changes and how the system performed at its second test, its first at a half-Senate election. (See How the new Senate Electoral System Performed at its first Half-Senate Election test.)

In this post I’m going to look at how voters reacted to the new electoral system and  whether they voted above or below the line. For each option, I look at how many preferences voters completed.

This will be the first of several posts over the next fortnight going into detail of how the Senate count unfolded in each state, how preferences flowed, and what impact parties and their how-to-votes had on preference flows.
