Tempered by the EU? Political parties and party systems before and after accession

Abstract

Party systems of European Union (EU) candidate states follow a predictable evolution over time. Before negotiations begin, most major political parties respond to EU leverage by adopting agendas that are consistent with qualifying for membership. Consequently, the party systems – at least for a while – reflect a consensus on the direction of domestic policy-making. Candidate states where regime change in 1989 was followed by illiberal democracy or authoritarianism are the most interesting. For key parties in these states, pushing for EU accession is a marker of profound moderation in their agendas. Yet after EU accession, the parameters for party competition broaden again. The lifting of accession-related constraints is especially apparent among parties that adopt more nationalist and culturally conservative positions. However, preliminary evidence suggests that such parties have made only modest political gains.
