Electoral and Partisan Forces in the Roosevelt Era: The U.S. Congressional Elections of 1938

Since nearly all studies of U.S. congressional elections test competing theories with data from the postwar era, we know very little about the applicability of contemporary theories to elections in the nineteenth and early twentieth centuries. This paper takes a first step in exploring theories of electoral politics in the historical context of the 1938 elections. I believe a closer look at this particular election is valuable for a variety of reasons. First, turnover among incumbents in 1938 was extremely high by contemporary standards, yet no systematic explanation for the record number of losses exists. Additionally, this political era was characterized by intense polarization between Congress and the president even though the Democrats controlled both institutions. An extended analysis of this historical era can also explore the role strategic challengers played in the electoral arena before the emergence of candidate-centered elections. By exploring these significant events, I shed light on an otherwise neglected aspect of American political development.
