Resumen de Estimating parties' left-right positions: Determinants of voters' perceptions' proximity to party ideology
The article aims to explore whether the accuracy of voters' perceptions of party ideology are affected by party position shifts and by the media's turn to non-left-right issues, such as political leadership, during election campaigns. Using data from the Comparative Study of Electoral Systems (CSES) and a country-specific left-right index based on data by the Comparative Manifestos Project (CMP), multilevel analyses reveal that emphasizing leadership issues can lead voters to reflect left-right positions more accurately. A party's left-right position shift between elections does not lead to a significant difference in voters' perceptions, while a shift on the economic sub-dimension of left-right ideology can even lead voters to more position clarity. However, multiple parties' shifting their positions seems to overburden respondents' cognitive capacity.
