Replication Data for: What difference does it makes? Explaining the voting behaviour of Partito Democratico's electorate and selectorate in 2013

This article analyses the differences in voting behaviour of the selectorate and electorate of the Italian Partito Democratico in 2013, particularly focusing on the role played by leadership, ideology and media in affecting voting decisions. We study the different motivations underlying the decision to vote for the Partito Democratico (PD) in the 2013 Italian general election or for each one of the three candidates to party leadership in the 2013 PD leadership selection race. The empirical analysis uses 2013 Italian National Election Study and 2013 Candidate & Leader Selection data. Results of the analysis show that leadership evaluation has a stronger influence on the selectorate than on the electorate and that the perceived distance between voters and the party on the left-right continuum has a stronger impact on the electorate than on the selectorate. Moreover, the analysis underlines that media are substantially not a relevant factor explaining voting behaviour of PD’s electorate and selectorate. These findings confirm the relevancy of leadership evaluation in intra-party competitions and open a new perspective to study leader selection races.
