Introduction to the special issue No longer second-order? Explaining the European Parliament elections of 2019

The dominant perspective of European Parliament (EP) elections is that these are second-order national elections where little is at stake. This Special Issue asks whether this perspective is still valid in view of increased politicization of European integration and in view of the higher turnout levels at the last EP elections. This introduction provides a general framework for the Special Issue and reflects upon some of its main findings. We argue that EP elections can only be considered first-order if they are primarily about the policies, rather than the polity. Some of the contributions in this Special Issue suggest that this is indeed the case. We reflect upon this and argue that there are reasons to expect that EP elections will become more first order in the future.
