Abstract

This study compares the spatial positioning of over 200 political parties across 28 European Union (EU) member states intwo cross-national voting advice applications (VAAs) developed for the 2014 European elections: EUvox and euandi. Wefind that the two VAAs show highly similar results in terms of party positioning on the cultural liberal-conservative andpro-anti EU dimensions, while economic left–right placements converge less, especially concerning right-wing parties. Ouranalyses reveal that the higher overlap on the cultural and EU dimensions is a result, at least partially, of the inclusion ofsimilar items used to measure these concepts, while most of the systematic divergence between the two VAAs in left–right placements stems from problematic issue-statements used in the dimensional calculations. We demonstrate howcertain items can cause bias in the placements of specific party families by (1) not aligning with other statements thatmeasure the same latent construct; (2) tapping into other latent constructs, in addition to the one they are supposed tomeasure; and (3) not inducing sufficient polarization between parties
