Changes in electoral practice since 2019

The coming general election is the UK’s first in approaching five years. Many changes have happened in how elections are done – partly through legislation, but partly also through informal shifts in the media, AI, and electoral administration. In this post, Sanjana Balakrishnan summarises all that is new.

The general election on 4 July will be the UK’s first since 2019. The intervening years have seen many changes to electoral process. These include important amendments in electoral law – most notably, but not exclusively, through the Elections Act 2022. They also include more informal shifts in, for example, the operating practices of social media companies and the capacity of local electoral administrators.

The breadth of these institutional changes means that July’s vote will be different from any previous UK general election. This post surveys the key points. It begins with legislative changes (on which the Hansard Society has offered an excellent and more detailed account) before turning to other innovations.

Elections Act 2022

The biggest set of reforms was introduced by the Elections Act 2022. Some of these changes related to local elections – see posts by the Unit’s Alan Renwick on mayoral and Police and Crime Commissioner (PCC) elections. The focus here is on those relevant to parliamentary elections.

Data-driven campaigning: the shape and perils of the modern election campaign

Political parties have access to an array of data that can potentially inform how they campaign. Kate Dommett, co-author of a new book on the subject, explains what data-driving campaigning is, the different ways in which parties use it, the problems it can cause, and how it might impact the next UK general election.

Imagine yourself running a party’s election campaign. Your mission in the run up to polling day is to develop a strategy for securing electoral victory or an increased vote share. You know that according to the latest social science research that campaigns can have important, if small effects on electoral outcomes. You know you will need to work to locate existing supporters and encourage them to turn out and cast their vote. You will also likely need to persuade undecided voters of the virtues of your party. And you will need to contact activists and motivate them to get involved in the campaign by donating money, attending campaign events or sharing party messages.

The key to all these activities is being able to communicate with the right audience. You do not want to be sending a reminder to vote to supporters of your opponents, and you do not want to waste money sending advertisements intended to persuade people who already plan to vote for you. You therefore need to gather and sort information about people’s voting behaviour to develop tailored messages. You also need to work out what messaging and mediums are most effective for achieving your desired goals. What slogans have the desired effect, what appeals prompt donations, and what campaign action most effectively reminds people to vote?

This form of campaigning is nothing new, but in recent years the availability of new forms of data, the emergence of new and more sophisticated techniques for profiling voters, and new mediums for contact are seen to have heralded a form of ‘data-driven campaigning’. Rather than relying on their gut instinct, party campaigners now use data and analytics insights to construct their campaign as never before. And yet, whilst increasingly common, our understanding of what exactly is captured by the term data-driven campaigning is often opaque.
