The anatomy of populist ideology: How political parties define ‘the people’ and ‘the elite'

Abstract Populist ideology centres around a supposed clash between the ‘honest and upright people’ and the ‘evil and corrupted elite’. Yet, which groups are perceived to constitute ‘the people’ and ‘the elite’ likely varies across parties. This research note investigates which factors explain how inclusive or exclusive the conceptions of these two core groups are. Why do some parties define the people in cultural terms, whereas others rely on economic considerations? And why do some parties consider CEOs as elites, whilst others consider academics as elites? We argue that parties’ degree of populism in combination with their ideological orientation allow us to understand these dynamics. In order to investigate these questions systematically, a new wave of the Populism and Political Parties Expert Survey (POPPA) was collected in 2023. Covering 312 political parties in 31 European countries in 2023, a novel module allows us to understand how parties define ‘the people’ and ‘elites’. We find that parties' populism and host ideology are important drivers of their people/elite conceptions. The higher a party's level of populism the more exclusionary its conception of the people is. Nativism is, moreover, associated with the exclusion of societal groups on cultural grounds, while left‐wing economic ideology drives the exclusion of societal groups on economic grounds. With respect to elites, populism is the most important determinant for parties' conceptions of the elite. By contrast, party ideology plays a subordinate role in parties' elite conceptions. This investigation has important implications for our understanding of populist parties, what the nature of their populist appeal is, and how they seek to mobilize in the political arena.
