Tapestries of Topics: Factors Affecting the Issue Diversity of Political Parties' Social Media Campaigns

For citizens to make well-informed decisions, they require information on diverse policy issues, which, among others, are publicized on political parties' social media accounts. However, as strategic actors, parties carefully weigh which issues to highlight and which to play down, rather than addressing a full range of issues in their campaigns. We investigated the hitherto neglected question of which issue diversity parties prioritize on their social media accounts and which factors influence this choice. We conducted a standardized content analysis of the official Facebook, Instagram, and Twitter accounts of 10 Norwegian parties and their leaders during the 2021 national election campaign. The results of our analyses indicate that issue -related campaign strategies influence parties' issue diversity more systematically than parties' governing/opposition statuses and their choices of social media platforms.
