Issue competition refers to the strategies deployed by political parties to increase or decrease the visibility of issues during a campaign in order to make political gains. Political scientists are particularly interested in the salience of electoral issues, as it is one of the variables that can influence voter behavior. Studies have shown that by focusing on distinct issues, parties seek to influence the media agenda to encourage debate on issues that are electorally favorable to them. This aspect of political competition illustrates how parties compete not only through the adoption of positions on a number of issues, but also through the emphasis they place on different issues. In recent years, research has empirically analyzed this phenomenon, finding that parties in fact tend to discuss largely the same issues during election campaigns. My project therefore aims to document the factors that lead political parties to converge in the attention they give to different issues. These factors include public concerns, media coverage and indicators of problem severity (e.g., unemployment rates or crime levels). This project aims to contribute to a better understanding of electoral strategies and their influence on public debates and voting behavior.
