Abstract: While conventional wisdom holds that partisan bias in US legislative elections results from intentional partisan and racial gerrymandering, we demonstrate that substantial bias can also emerge from patterns of human geography. We show that in many states, Democrats are inefficiently concentrated in large cities and smaller industrial agglomerations such that they can expect to win fewer than 50 percent of the seats when they win 50 percent of the votes. To measure this "unintentional gerrymandering," we use automated districting simulations based on precinct-level 2000 presidential election results in several states. Our results illustrate a strong relationship between the geographic concentration of Democratic voters and electoral bias favoring Republicans.
An Application to the Senate Confirmation of Presidential Nominees. (with Adam Bonica and Tim Johnson)
Revise and Resubmit, Quarterly Journal of Political Science.
Abstract: This paper uses political campaign contributions to estimate public bureaucrats' political ideologies. Bureaucrat ideal points estimated via our method vary across time, compare meaningfully with ideological estimates in other branches of government, cover employees across a wide range of agencies, yield insight into intra-agency ideological variation, and are produced automatically from public records. To demonstrate our method, we estimate the political ideologies of appointed administrators in the U.S. federal government. We then use those estimates to test hypotheses about how U.S. presidents strategically manage the process of appointing individuals to federal bureaucratic posts requiring Senate confirmation.

Abstract: How does the size of a legislature affect the competitiveness of its districts' elections? This paper theoretically develops and empirically tests three hypotheses concerning the effect of legislative chamber size on electoral competition and partisan gerrymandering. First, in swing states, legislature size has a negative effect on the fraction of districts that are electorally competitive; the intuition here is that smaller districts are more politically homogenous and thus less competitive. Second, in those few states that are extremely Democratic (e.g., New York) or extremely Republican (e.g., Alabama), legislature size has a single-peaked relationship with electoral competitiveness: Moderate-sized legislative chambers produce the most competitive districts. Finally, because political gerrymanderers often seek to manipulate electorally vulnerable districts, a decline in competitive districts should cause a decrease in partisan gerrymandering. Therefore, among swing states, larger legislative chambers should exhibit less gerrymandering than smaller chambers. To empirically test these three arguments, I first present data from state legislative election results during 1992-2002. I then conduct automated, repeated simulations of state legislature and Congressional districting across several states. These simulations allow us to isolate the effect of legislature size on electoral competitiveness, thus removing confounding factors such as gerrymandering, candidate quality, and incumbency advantage. Finally, in order to measure the extent of gerrymandering in each legislative chamber, I compare real-life districting plans against the simulated districting plans. By comparing these two sets of plans, I estimate the extent to which gerrymanderers politically manipulated legislative districts in the 2002 redistricting cycle.
Abstract: We present a model predicting that presidents strategically use unionization to reduce bureaucratic turnover and to "lock-in" the ideological composition of like-minded agency workforces. Consistent with the predictions of our model, we report empirical evidence indicating that federal employee unionization occurs more frequently in agencies that are ideologically proximate to the president. Furthermore, agencies with fewer unionized employees experience higher levels of personnel turnover and greater ideological volatility when the president's partisanship changes. Agencies with a greater proportion of unionized employees, by contrast, experience less personnel turnover during presidential transitions, and they remain more ideologically stable across presidencies.
Abstract: This paper presents a new method of estimating the ideal points of US federal agencies using the campaign contributions of bureaucrats employed by each agency. Ideal points are calculated by examining the Common Space DW-NOMINATE scores of incumbent federal politicians who receive campaign contributions from each agency's bureaucratic personnel. These ideal point estimates exhibit face validity under tests of some basic hypotheses about the partisan control of bureaucratic agencies. The substantive contribution of this paper is to show that the most right-wing agencies under a Republican administration often become the most leftwing agencies under a Democratic presidency. That is, agency ideal points under a Republican president exhibit a negative correlation with agency ideal points under a Democratic administration.
