Retrospective voting is a central explanation for voters’ support of incumbents. Yet, despite the variety of conditions facing American cities, past research has devoted little attention to retrospective voting for mayors. This paper first develops hypotheses about how local retrospective voting might differ from its national analog, due to both differing information sources and the presence of national benchmarks. It then analyzes retrospective voting using the largest data set on big-city mayoral elections between 1990 and 2011 to date. Neither crime rates nor property values consistently influence incumbent mayors’ vote shares, nor do changes in local conditions. However, low city-level unemployment relative to national unemployment correlates with higher incumbent support. The urban voter is a particular type of retrospective voter, one who compares local economic performance to conditions elsewhere. Moreover, these effects appear to be present only in cities that dominate their media markets, suggesting media outlets’ role in facilitating retrospective voting.
