The effects of political involvement and cross-pressures on multiple party identifications in multi-party systems – evidence from Germany

<p>Despite being part of the original concept in “The American Voter”, multiple party identifications (MPID) have rarely been analyzed. Based on a 2016 survey that is representative of the German electorate, we investigate the determinants of multiple party attachments in Germany. With the help of a new measurement instrument for MPID, we can show that multiple attachments are a common phenomenon in Germany: Nearly 30% of the respondents and more than half of all party adherents identify themselves with more than one party. Political interest and education as facets of political involvement have a significant effect on the likelihood of holding multiple attachments within ideological camps. Cross-pressures lead to a higher probability of having multiple identifications between political camps.
