Intra-Party Dissent as a Constraint in Policy Competition: Mapping and Analysing the Positioning of Political Parties in the German Refugee Debate from August to November 2015

The large influx of refugees into Germany in late 2015 gave rise to a period of intensified party competition over a single issue: refugees. This paper examines German parties' reactions to this issue suddenly becoming highly important and voter preferences shifting to a more restrictive stance. It does so by analysing the parties' positions on the issue from August to November 2015 based on statements from more than 1000 quality newspaper articles. The analysis shows that there was no uniform shift in line with the change in public opinion but a pattern of polarisation. Moreover, converging party position changes sparked intra-party criticism that was in turn followed by divergence - a pattern observable for the Green Party as well as for the Christian Democrats. Altogether, these findings suggest that policy motives, which induce intra-party dissent, impede parties opportunistically trying to follow shifts in public opinion in the short term.
