Sorting between and within coalitions: the Italian case (2001–2008)

Abstract How do voters sort within an electoral coalition? Voting literatures on ideology, character valence, and issue ownership provide explanations for inter-coalition or inter-party voting, yet the coalition context remains understudied. Do voters in proportional coalition-based systems use the same ideological and issue-based heuristics ascribed to them in two-party systems that favor single-party government? Voting behavior in Italy in the 2000s is used to explore this question. This paper examines what motivates the voters of the large center-left and center-right coalitions, specifically whether ideology, economic issues, or other considerations lead voters to select their party of choice. Results indicate that, on average, voters select a coalition ideologically-proximal and deemed the more competent on issues, while they select a specific party based upon character and reputation issues. Findings thus suggest that voters sort for both coalition and party-specific reasons.
