Replication Data for: Religion, identity, and party preference: The role of Catholicism in the 2022 Italian National elections

This paper contributes to the debate on the role of religiosity in party competition in democratic political systems by analyzing the role of religious practice and belonging in the 2022 Italian elections. By using the newest ITANES dataset, we combine indicators of both religious affiliation and practice to show how the electorates of the main Italian parties are composed in terms of voters’ religiosity, to highlight how these differences influence the probability to vote for each of those parties and to further investigate the relationship between religious affiliation/practice and voting behavior. Results show the emergence of an increasingly identity-based relationship between religiosity and vote within the Italian context. We find that religiosity – in the form of Catholic affiliation - maintains a direct effect on vote choice which is also partially mediated by attitudinal indicators, such as those toward immigration, homosexuality, and abortion. We conclude that party competition in Italy is mainly fueled by and grounded on identity dynamics – and less on religious practice or beliefs – concerning the whole group of those who identify as Catholics opposed to the group of those who do not.
