Concept and goalThe GLES Rolling Cross-Section was conducted prior to the 2021 federal election using daily cross-sectional samples. Rolling cross-sectional studies are a standard tool for capturing changes in the political attitudes and behaviors of respondents. The GLES Rolling Cross-Section thus allows for analyses of campaign dynamics among people eligible to vote at the level of daily assessments. The additional implementation of a post-election panel wave also allows for investigating intra-individual changes over the course of the campaign.
