SISTEMA DE VOTACIÓN PREFERENCIAL. EFECTOS EN LA COMPETENCIA INTERNA DE LOS PARTIDOS Y EN EL COMPORTAMIENTO ELECTORAL

This article reports the effects of preferential voting on intraparty electoral competition and voting behavior. This study sheds light on a somewhat neglected aspect of electoral systems. The author demonstrates that the ability of voters to influence the selection and deselection of MPs under preferential voting systems is not as important as is often assumed. Instead, their ability to shape the election of a given candidate depends heavily on the balance between party power and voter power. In this way, this article advances the understanding of the effect of preferential voting on intra-party dynamics, parliamentary turnover, and voter behavior. Based on a rigorous, data-led methodological approach, the article contributes to both the theory and practice of the study of electoral systems.
