We are currently witnessing a new chapter in the politicisation of EU affairs in the German parliament, the Bundestag. German legislators were asked to vote on further aid measures for Greece three times this year, and support within Chancellor Angela Merkel’s and Finance Mininster Wolfgang Schäuble’s own party (the Conservative CDU) has gradually declined. On the 19th August, when the Bundestag ratified the third financial aid package for Greece, 1 in 5 Christian Democrats voted against the government. Who are these dissenters? Can the party leadership expect an increase in defecting voting behaviour?
