The coalition agreement of 2013 between the CDU/CSU and the SPD contained 188 concrete measures and goals. In February 2018 the Bertelsmann Foundation published a study that analyzed them in detail. The government had carried out 80 percent of them, fully or in part.
Yet only 13 percent of eligible voters believed that all, almost all or a large part of the promises had been kept. The largest group, 38 percent, believed that only a small part, or hardly any, had been kept.
The record was better than its reputation. The study called the difference a very painful credibility gap.
