Voting on Europe, again and again: Stability and change in the Irish experience with EU referendums

This article is about comparative voting behaviour in referendums on the EU and explores variation within one country rather than variations across countries. This enables us to control for broad national context while allowing variations in the immediate referendum context, in terms of campaign intensity and incumbency. It analyses voting behaviour in the many referendums that have taken place in Ireland. The major part of the analysis deals with the five referendums since 2001, as this allows the use of the same measurement of EU support and the use of post referendum surveys. Most attention is paid to attitude to the EU, party support and satisfaction with the incumbent government, reflecting the main debates in the literature on the issues and party cues. The relative importance of each is said to depend on contextual factors such as campaign intensity and economic strength. We find both party cues and issues matter consistently, and suggestive evidence that incumbency matters to the effectiveness of cues given by the two main pro-EU parties but the major finding is that variations in the factors driving voting behaviour in different Irish polls on Europe are slight and barely significant.
