We recommend all scholars interested in using the data to first read the Introductory Guide, and to peruse the various codebooks (especially the one of the Twitter dataset) to get a correct understanding of the various – sometimes innovative – measures included in the various datasets.
Among these, there are new, issue-yield based measures that were developed for the project, allowing:
- the identification of optimal issue opportunities that were available to each party before the final campaign;
- whether and to what extent different parties indeed exploited strategically these available issue opportunities in their campaign activity.
Preliminary results show that some parties were more strategic than others in these terms; and that such parties were indeed rewarded by better electoral performance. This casts a new light on the 2017-18 wave of elections; not necessarily a success only for “populist” parties, but for all those parties that actively exploited their available issue opportunities. Thus, with clear strategic suggestions even for the future strategies of mainstream parties.
