The 2019 general election is in full swing and political parties are relying on digital campaigning more than ever before. Targeted marketing has made a profound change in how political parties can reach you and our compulsion to click, like and share can be used against us in surprising ways. We speak to Kirk J. Torrance, a former digital strategist for the SNP, who worked on their landslide 2015 campaign. The BBC’s Maryam Ahmed has built an algorithm to catch all targeted political advertising on Facebook for this election. And Latika Bourke, reporter for the Sydney Morning Herald, tells us how the Australian election was won with the help of Game of Thrones.
