Voter Decision-Making with Polarized Choices
In: British journal of political science, Band 48, Heft 1, S. 1-22
Abstract
In 1950, members of the American Political Science Association's Committee on Political Parties argued that voters could exercise greater control over government if the two major political parties adopted clear and ideologically distinct policy platforms. In 2015, partisan polarization is a defining feature of American politics and extreme parties have maintained support elsewhere. This article investigates voter decision-making with ideologically divergent electoral choices and argues that ideological conflict reduces citizens' responsiveness to candidates' ideological locations by increasing the role of motivated reasoning in political decision-making. Results from two observational studies and a survey experiment support this account, and the findings are robust across a range of models. These results have important implications for accountability and democratic decision-making in an age of partisan polarization.
