Résumé : This research note analyses the communication of Belgian political parties and their leaders before and during the June 2024 electoral campaign, focusing on X (formerly Twitter). We rely on the full population of posts on X that were disseminated by political parties and presidents from February 9 2023 until June 8 2024 (n = 16,084). We examine the issues that political parties emphasised the most during the campaign (n= 4,979), and whether these priorities shifted compared to the pre-campaign period (n=11,105). We analyse whether these political actors have emphasised similar or different issues, and the extent to which they aligned or changed their communication during the campaign to fit with the agenda-setting of a dominant party or to salient issues in general.
