| Concept and goal | The GLES Rolling Cross-Section is a survey conducted in the form of a rolling cross-section prior to the 2009, 2013 and 2017 Bundestag elections. The RCS allows the analysis of election campaign dynamics on a daily basis. The implementation of a post-election panel wave also makes it possible to investigate intra-individual changes in the course of the campaign. |
