The U-curve in euroscepticism is well established: both leftist and rightist populist constituencies are more eurosceptic than voters for establishment parties. Using rich survey data on a country with both constituencies represented in parliament (the Netherlands; n=1,296), we examine why euroscepticism drives populist voting. Our analyses demonstrate that euroscepticism is part of the well-established link between both 1) distrust in politics and politicians, and 2) support for protectionism on the one hand, and voting for both types of populist party on the other. It is also part of the well-known relationship between 3) ethnocentrism and rightist populist voting. Surprisingly, euroscepticism is not part of the typical association between economic egalitarianism and voting for a leftist populist party. The concluding section discusses the implications of our findings and provides suggestions for further research.
