Erik J. Engstrom is Professor of Political Science at the University of California, Davis.

"Explorations of American political history often demonstrate that patterns or influences familiar today also existed in the past. Erik Engstrom’s new book Partisan Gerrymandering and the Construction of American Democracy does not fit that mold. In the course of a thoroughgoing examination of redistricting in the nineteenth century, Professor Engstrom addresses a major contemporary disconnect between the beliefs of practicing politicians and the prevailing conclusions of the academic community. Both Democrats and Republicans expend significant resources trying to position their party to draw post-census maps for Congress and state legislatures and, if unsuccessful in those efforts, they attack the handiwork of the opposition in the courts. Despite the significance accorded redistricting by practicing politicians, the consensus among political scientists is that gerrymandering has little impact on party fortunes. Professor Engstrom makes a compelling case that, in the past, the creation of districts made a difference, at times even tilting the balance in Congress and thereby impacting consequential policy decisions. This meticulously researched volume explores the consequences of districting—or, as in the early days of the republic—the decision by some states not to district, but to elect their delegations at-large."

"Decennial redistricting, equal population, majority-minority districting, have transformed contemporary redistricting, but a look to the past, as deftly analyzed by Engstrom, better informs us of how altering voting boundaries impacts politics."
--Political Science Quarterly

“[Partisan Gerrymandering and the Construction of American Democracy is] a nice mix of history and quantitative analysis...It will be the definitive work on the subject for decades to come.”
—Charles Stewart III, Massachusetts Institute of Technology

“The partisan gerrymandering of congressional districts is a contentious political problem today. But the history of partisan districting goes back to the early days of the republic. Erik Engstrom offers a brilliant tour of this history and its impact on American political development. He shows how, from the nation’s beginning, American state legislators had both the will and the ability to exploit the districting process for partisan advantage.”
