When casting a split-ticket ballot, voters in established democracies have strong political predispositions and electoral experience that influence their decision. However, voters in a new democracy, lacking long-term party attachment and experience with democracy, may instead be informed and motivated by their social networks. Using the 1990 Cross-National Election Project German Unification study, I examine which factors predict split-ticket voting for East and West Germans. I find that political disagreement within a social network is more influential for East Germans, while partisan predispositions, particularly party supporter type, play a greater role for West Germans. These findings indicate that, in absence of competition between long-term partisanship and democratic experience, network characteristics may have a profound impact on political decision-making.
