Comparative Campaign Dynamics Dataset


This collection of data sets provides information on ideological cohesion and ambiguity of party positions along with information on framing effects by competing parties and the media. The data covers the policy standpoints parties and their representatives have communicated in the media along with valence-related statements, such as references to competence or integrity. Coding was based on pre-electoral coverage of major newspapers for two recent (national) electoral campaigns in ten European countries. The three separate data sets focus on the statements parties have made referring to themselves, the statements they have made referring to their competitors and the statements the newspapers have made referring to the parties.
