Out of Step, Out of Party
Do parties shape legislators' revealed behavior, or do they merely reflect it? Party switchers offer a rare opportunity to examine party effects because the same legislators can be observed before and after crossing the aisle. I assemble a dataset of 500 state legislative party switches across 49 states from 1993 to 2024 and use comparable ideal‐point estimates to examine two questions: what predicts switching, and how much legislators' voting re…
Are State Legislative Leaders Moderates
Spatial models of legislative organization predict that elected leaders will be moderates with respect to their constituency, the party caucus. However, empirical studies of leader positioning in Congress find mixed evidence that this is the case. This paper expands the analysis to state legislatures, using an original dataset of 2056 top chamber and party leaders in 50 states from 1999 to 2023. Simulations reveal that state legislative leaders a…
Geography, Uncertainty, and Polarization
Using new data on roll-call voting of US state legislators and public opinion in their districts, we explain how ideological polarization of voters within districts can lead to legislative polarization. In so-called “moderate” districts that switch hands between parties, legislative behavior is shaped by the fact that voters are often quite heterogeneous: the ideological distance between Democrats and Republicans within these districts is often g…
Ideology, Party, and Opinion
Why do state legislators vote the way they do? Which influence is predominant: ideology, party, or public opinion? The implementation votes surrounding the Affordable Care Act (ACA) provides a unique setting to examine this question, as they make all three considerations highly salient. State roll call votes on ACA implementation were sometimes polarized and sometimes unexpectedly bipartisan. What accounts for the heterogeneity in individual legi…
Reform and Representation
Can electoral reforms such as an independent redistricting commission and the top-two primary create conditions that lead to better legislative representation? We explore this question by presenting a new method for measuring a key indicator of representation—the congruence between a legislator’s ideological position and the average position of her district’s voters. Our novel approach combines two methods: the joint classification of voters and …
Ideology and the US Congressional Vote
A large class of theoretical models posits that voters choose candidates on the basis of issue congruence, but convincing empirical tests of this key claim remain elusive. The most persistent difficulty is obtaining comparable spatial estimates for winning and losing candidates, as well as voters. We address these issues using candidate surveys to characterize the electoral platforms for winners and losers, and large issue batteries in 2008 and 2…
Do Moderate Voters Weigh Candidates’ Ideologies? Voters’ Decision Rules in the 2010 Congressional Elections
Has the Top Two Primary Elected More Moderates
Party polarization is perhaps the most significant political trend of the past several decades of American politics. Many observers have pinned hopes on institutional reforms to reinvigorate the political center. The Top Two primary is one of the most interesting and closely-watched of these reforms: a radically open primary system that removes much of the formal role for parties in the primary election and even allows for two candidates of the s…
Ideology, Learning, and Policy Diffusion
We introduce experimental research design to the study of policy diffusion in order to better understand how political ideology affects policymakers’ willingness to learn from one another's experiences. Our two experiments–embedded in national surveys of U.S. municipal officials–expose local policymakers to vignettes describing the zoning and home foreclosure policies of other cities, offering opportunities to learn more. We find that: (1) policy…
Polarization without Parties
Despite a long history of nonpartisanship, the Nebraska state legislature has polarized rapidly within the past decade. Using interviews and campaign finance records, we examine politics in the modern Unicam to investigate nonpartisan polarization. We find that newly instituted term limits created opportunities for the state's political parties to recruit and finance candidates in an increasingly partisan fashion. Social network analysis suggests…

A Primary Cause of Partisanship? Nomination Systems and Legislator Ideology
Many theoretical and empirical accounts of representation argue that primary elections are a polarizing influence. Likewise, many reformers advocate opening party nominations to nonmembers as a way of increasing the number of moderate elected officials. Data and measurement constraints, however, have limited the range of empirical tests of this argument. We marry a unique new data set of state legislator ideal points to a detailed accounting of p…
Red State/Blue State Divisions in the 2012 Presidential Election
The so-called “red/blue paradox” is that rich individuals are more likely to vote Republican but rich states are more likely to support the Democrats. Previous research argued that this seeming paradox could be explained by comparing rich and poor voters within each state – the difference in the Republican vote share between rich and poor voters was much larger in low-income, conservative, middle-American states like Mississippi than in high-inco…
The Ideological Mapping of American Legislatures
The development and elaboration of the spatial theory of voting has contributed greatly to the study of legislative decision making and elections. Statistical models that estimate the spatial locations of individual decision-makers have made a key contribution to this success. Spatial models have been estimated for the U.S. Congress, the Supreme Court, U.S. presidents, a large number of non-U.S. legislatures, and supranational organizations. Yet …
A Bridge to Somewhere
Researchers face two major problems when applying ideal point estimation techniques to state legislatures. First, longitudinal roll‐call data are scarce. Second, even when such data exist, scaling ideal points within a single state is an inadequate approach. No comparisons can be made between these estimates and those for other state legislatures or for Congress. Our project provides a solution. We exploit a new comparative dataset of state legis…
Rich State, Poor State, Red State, Blue State
For decades, the Democrats have been viewed as the party of the poor, with the Republicans representing the rich. Recent presidential elections, however, have shown a reverse pattern, with Democrats performing well in the richer blue states in the northeast and coasts, and Republicans dominating in the red states in the middle of the country and the south. Through multilevel modeling ofindividual-level survey data and county- and state-level demo…
A Bayesian Multilevel Modeling Approach to Time-Series Cross-Sectional Data
The analysis of time-series cross-sectional (TSCS) data has become increasingly popular in political science. Meanwhile, political scientists are also becoming more interested in the use of multilevel models (MLM). However, little work exists to understand the benefits of multilevel modeling when applied to TSCS data. We employ Monte Carlo simulations to benchmark the performance of a Bayesian multilevel model for TSCS data. We find that the MLM …
