A Step Closer to a Transnational Party System? Journal of Common Market Studies.
At this stage of European integration and given the high degree of Europe’s politicization and salience caused by the recent global financial crisis, representative democracy in the EU can only function if parties mobilize beyond borders. We examine whether European Party Groups (EPG) in the European Parliament (EP) offer distinct policy alternatives and how coherent these are. We
use party position data collected by two Voting Advice Applications designed for the 2009 and 2014 EP elections, respectively (EUProfiler and Euandi). We find evidence of competition between EPGs groups on both left right issues and European integration; on the latter issue, there is greater differentiation within the anti-EU camp. Coherence within EPG exists, though it varies across issues, EPGs and between election years examined: it is greater on European integration
than on left–right issues and it is particularly high for right wing eurosceptics though for most parties it deteriorates between 2009 and 2014.
