This study draws together theories of women’s substantive representation and research on politicians’ knowledge of constituent preferences. We ask whether politicians are better at predicting their constituents’ policy preferences when they share the same gender. In doing so, we contribute to knowledge about the mechanisms underlying substantive representation. Using original surveys of 3,750 Canadians and 867 elected politicians, we test whether politicians correctly perceive gender gaps in their constituents’ policy preferences and whether women politicians are better at correctly identifying the policy preferences of women constituents. Contrary to expectations from previous research, we do not find elected women to be better at predicting the preferences of women constituents. Instead, we find that all politicians — regardless of their gender — perform better when predicting women’s policy preferences and worse when predicting men’s preferences. The gender of the constituent matters more than the gender of the politician.

This article examines the effect of corruption on ideological voting. Linking previous studies of political corruption with theories of ideological voting, it argues that when corruption is high, voters place less importance on ideology when voting than they otherwise would. The reason for this effect is related to voters’ reduced ability to accurately perceive parties’ positions and to their low political efficacy in these contexts. Using data from ninety-seven elections from the Comparative Study of Electoral Systems, the study shows that in countries with high levels of corruption, voters consider ideology less in their voting decisions, partially because they face difficulties identifying parties’ ideological positions and/or they do not believe parties can implement their electoral programmes. These relationships hold even after controlling for socio-economic and political confounders and for voters’ increased likelihood of abstaining when corruption is high.
