How congruent are populist parties with their constituencies? Evidence from the 2019 European Parliament Elections in Italy, the Netherlands, Germany and Sweden

The rise of populism in Europe has often been described as a response to representation deficits. Arguably, populist parties (1) contribute to the representation of underrepresented constituencies by taking stances that non-populist parties are too constrained to advocate and (2) make a promise of extreme responsiveness to those frustrated with the lack of representation. In this research note, we investigate whether populist parties are indeed closer to their voters in the policy space than non-populist parties and are more congruent with their constituencies than the other parties are with theirs. Using data from Italy, Germany, the Netherlands, and Sweden, we find that populist parties are indeed often the best policy option for their voters, but the correspondence between their positions and those of their constituencies is on average as good or bad as that between other parties and their voters.
