What explains the lack of electoral consequences for corrupt politicians? Building on studies of motivated reasoning and asymmetric partisan bias, this article highlights the importance of partisan differences in how voters interpret corruption convictions and make voting decisions. I contend that in post-authoritarian democracies, supporters of authoritarian legacy parties (ALPs) are less likely to punish corrupt copartisan incumbents compared to supporters of other parties faced with equally corrupt copartisan incumbents. While voters of all kinds appear likely to ignore corruption among copartisan incumbents, supporters of authoritarian legacy parties are particularly likely to do so. Using original datasets from South Korea, this study shows empirical evidence of the lack of corruption voting for ALP partisans across three legislative elections. This article further finds partisan discrepancies and a striking lack of corruption voting among authoritarian legacy partisans.
