Sovereignism is at the crux of the current wave of radical right-wing populism (RRP).
While sovereignism may concern different dimensions, claims by RRP parties and leaders
about regaining sovereignty are increasingly associated with socioeconomic issues such as
welfare, redistribution and international trade. Adopting a demand-side perspective, this
article draws from an original cross-national survey to investigate the intersection between
economic sovereignism, economic populism and globalization attitudes, and how such
attitudes may shape RRP voting in Western Europe and the United States. Our results
confirm that economic populism and sovereignism form coherent sets of attitudes
together with perceptions of globalization, and that such attitudes have a significant effect
on support for RRP actors. We find different patterns of association, however, across our
European cases and the United States, which suggests that the relationship between populism,
sovereignism and economic globalization is partly dependent upon national context
and historical legacies.
