Abstract Whether fiscal austerity by governments is unpopular or not is much discussed in the literature. One line of research argues that consolidation has negative electoral effects, ranging from declines in politicians’ approval ratings to abstention by voters at elections. Another strand highlights that re-election chances are not harmed by the implementation of austerity and that some voters in fact support consolidation measures. Both sides are limited in at least two regards. First, they do not allow for the possibility that public opinion is shaped by the political discussion about government debts and budget deficits. Second, and relatedly, the literature is limited in its extent to which it considers heterogeneity in preference adaptation across income groups. This article contributes to these debates by bringing to bear insights from the literature on mass preference formation. In particular, I argue that a cross-party consensus on austerity leads voters to align their preferences with the consensus, increasingly demanding cuts to government spending. This adaptation is conditioned by income so that the preferences of those income groups that are the furthest away from the consensus adapt their fiscal preferences most. By including the discursive context of fiscal policy, this article helps explain how austerity can be made popular. Empirically, I test these expectations by matching citizen preferences with party positions on fiscal policy for 60 country years. The empirical results indeed demonstrate that even though low- and middle-income voters are least supportive of austerity, they adapt the most to the party consensus on austerity.
