These are the replication files for the artile A Step Closer to a Transnational Party System? published in Journal of Common Market Studies https://doi.org/10.1111/jcms.12755. The data used are the EU Profiler and EUandI party data both to be found at GESIS: http://dx.doi.org/10.4232/1.11689 and http://dx.doi.org/10.4232/1.12138

These replication files contain a file that adds to the above mentioned data the number of seats for each party in the European parliament, and a file that runs our analysis and creates our graphs for both election years 2009 and 2014.

Abstract of the paper: At this stage of European integration and given the high degree of Europe’s politicization and salience caused by the 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.
