Time is on my side? The temporal proximity between elections and parties’ salience strategies

Abstract The emphasis national parties put on European Union (EU) issues in their manifestos varies to a great extent between countries. A systematic explanation of this variation is, however, still lacking. We address this gap by exploring the effect of the temporal proximity between national and European Parliament (EP) elections within the national electoral cycle on national parties’ EU issue emphasis. Multilevel mixed-effects Tobit regressions on a sample of 956 manifestos, produced by 340 parties running for national elections in 27 EU member states between 1979 and 2019, indicate that temporal proximity displays a positive effect on national parties’ EU issue salience: the closer in time EP elections are to national elections within the national electoral cycle, the more parties emphasize EU issues in their national election manifestos. This is particularly the case for non-Eurosceptic parties. These findings have important implications for our understanding of party competition in EU member states.
