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.
