The literature on the incumbency advantage in U.S. House elections has focused mostly on political variables, such as competition and incumbent resources. For this article, I identify an important sociological variable: a cohort effect that separates older generations from younger ones. Younger generations have been more likely to vote for incumbents, and the difference has endured over time, even as the political environment itself has changed and become more partisan. Moreover, the results hold even when one controls for partisan identification and general time‐period effects. The incumbency advantage may be a broader and more‐enduring part of American politics than has previously been recognized.
