Data sets of two rolling cross-section pre-election surveys with post-election panel wave of voters at the time of the 2009 and 2013 German general election campaigns. The data was collected as part of the German Longitudinal Election Study (GLES).
At the German Federal Election of 2009 a daily rolling cross-section (RCS) campaign survey was conducted within the framework of the GLES with 100 interviews per day on average for the final 60 days of the campaign. Interviewing was organized in such a way that not only the entire sample but also the subsamples available for each day of the campaign constitute random samples of the universe of all voters. Conducted by telephone (CATI), it thus produced about 6,008 interviews in total. 4.027 of the pre-election respondents were re-interviewed after the election.
At the German Federal Election of 2013 the study was replicated: The pre-election field period was extended to 76 days and on average about 104 respondents were interviewed per day. Altogether this yielded 7.882 pre-election interviews. 5.353 respondents were re-interviewed after the election.
