The public perceives the Supreme Court to be a legal institution. This perception enables the Court’s legitimacy-conferring function, which serves to increase public acceptance of its decisions. Yet, the public acknowledges a political aspect to the Court as well. To evaluate how the public responds to the different images of the Supreme Court, we investigate whether and how depictions of specifically partisan (e.g., Republican) Court rulings shape public acceptance of its decisions while varying institutional, legal, and issue characteristics. Using survey experiments, we find that party cues and partisanship, more so than the imprimatur of the Court, affect public acceptance. We also find that polarization diminishes the effect of party cues. Attributing a decision to the Court does little to increase baseline acceptance or attenuate partisan cue effects. The Court’s uniqueness, at least in terms of its legitimacy-conferring function, is perhaps overstated.

We argue that the Supreme Court’s expressed and latent demand for information on the availability and implications of legal policy alternatives will affect the supply of information provided to the Court by organized interests. An analysis of the annual growth in amicus filings at the Court during the 1949 through 2008 terms largely supports our specific hypotheses. The rate at which the Court cites amicus briefs and shifts in the Court’s ideological location or agenda exert a positive effect on the growth of amicus filings, while the evidence for the effect of dissensus is mixed. We further show that the supply of briefs does not affect the Court’s expressed or latent demand for information.

Studies of Court–Congress relations assume that Congress overrides Court decisions based on legislative preferences, but no empirical evidence supports this claim. Our first goal is to show that Congress is more likely to pass override legislation the further ideologically removed a decision is from pivotal legislative actors. Second, we seek to determine whether Congress rationally anticipates Court rejection of override legislation, avoiding legislation when the current Court is likely to strike it down. Third, most studies argue that Congress only overrides statutory decisions. We contend that Congress has an incentive to override all Court decisions with which it disagrees, regardless of their legal basis. Using data on congressional overrides of Supreme Court decisions between 1946 and 1990, we show that Congress overrides Court decisions with which it ideologically disagrees, is not less likely to override when it anticipates that the Court will reject override legislation, and acts on preferences regardless of the legal basis of a decision. We therefore empirically substantiate a core part of separation-of-powers models of Court–Congress relations, as well as speak to the relative power of Congress and the Court on the ultimate content of policy.

We propose a dynamic model of precedent in a judicial hierarchy which incorporates a “bottom-up” informational component. When a high court establishes precedents, it has uncertainty regarding how they will play out when applied to future legal disputes. Lower court implementation of these precedents can inform the high court about the contemporary policy implications—i.e., the ideological location—of the precedents. If lower court usage of a precedent is informative, the high court will consider the revealed location of the precedent when contemplating reducing the precedent’s authority and applicability to future cases. Using data on U.S. Supreme Court precedents and U.S. Courts of Appeals citations to these precedents, we estimate a model of the Court’s negative treatment of precedent. We find lower court usage of precedent can provide new, useful information on the policy content of a precedent, helping the Court shape law in a way consistent with its preferences.

How do organized interests respond to their opponents’ advocacy activities in a policy venue? Utilizing data on amicus curiae filings at the U.S. Supreme Court, the author estimates vector error correction and vector autoregression models that allow him test whether interests respond, in a dynamic sense, to the efforts of the “other side.” The author capitalizes on the temporal sequencing of variation in advocacy activity to gain leverage on the causal connection between the behaviors of opposing sets of interests and provides a richer portrait of the dynamics of interest representation in a policy venue. The results reveal that organized interests respond positively to the advocacy activities of their opponents by exhibiting both short-term counteraction and long-term countermobilization, implying that over the long run, interest representation at the Court is responsive and perhaps balanced.

This article examines the electoral consequences of variation in voter turnout in the United States. Existing scholarship focuses on the claim that high turnout benefits Democrats, but evidence supporting this conjecture is variable and controversial. Previous work, however, does not account for endogeneity between turnout and electoral choice, and thus, causal claims are questionable. Using election day rainfall as an instrumental variable for voter turnout, we are able to estimate the effect of variation in turnout due to across-the-board changes in the utility of voting. We re-examine the Partisan Effects and Two-Effects Hypotheses, provide an empirical test of an Anti-Incumbent Hypothesis, and propose a Volatility Hypothesis, which posits that high turnout produces less predictable electoral outcomes. Using county-level data from the 1948–2000 presidential elections, we find support for each hypothesis. Failing to address the endogeneity problem would lead researchers to incorrectly reject all but the Anti-Incumbent Hypothesis. The effect of variation in turnout on electoral outcomes appears quite meaningful. Although election-specific factors other than turnout have the greatest influence on who wins an election, variation in turnout significantly affects vote shares at the county, national, and Electoral College levels.

Prior studies hypothesize that judges time their retirements to allow a like-minded president to select their replacements. We propose a modification to this argument and theorize that during the earlier part of a district court judge’s career, it is the likelihood of elevation to an appeals court and other career-oriented concerns that affect whether the judge resigns or stays on the bench. It is during the latter stage of a judge’s career when the desire to be replaced with a like-minded judge affects the retirement decision. Our analysis reveals that judges who are not yet pension eligible are influenced by being passed over for appeals court nominations as well as financial incentives to leave for private practice. Only judges who have attained pension eligibility appear to consider their ideological compatibility with the president when deciding to call it quits.

We contend that a candidate’s decision to exit from a U.S. presidential nomination campaign is a function of three sets of considerations: the potential for profile elevation, party-related costs, and updated perceptions of competitiveness. We analyze data from eleven post-reform presidential nomination campaigns and find support for all three considerations. Specifically, our results suggest that in addition to candidates’ competitiveness, the decision to withdraw is a function of candidates’ closeness to their party and ability to raise their profile. At the same time, some of our results contradict the conventional wisdom regarding presidential nomination campaigns, as we find no evidence that media coverage or cash on hand directly affect the duration of a nomination candidacy.

If you could start a political science program from scratch, how would you do it? Given no institutional history, how would you design graduate and undergraduate programs? How would you grow your faculty? How would you attempt to build a reputation in the absence of a reputation at time t-1? In an interdisciplinary environment, with which disciplines would you work most closely? For most political science professors, these might be interesting hypothetical questions to consider. For the two of us, these questions are very real and have dominated our recent work lives as we have just finished our first year as the founding political science faculty at the brand new University of California campus, UC Merced.

The relationship between bad weather and lower levels of voter turnout is widely espoused by media, political practitioners, and, perhaps, even political scientists. Yet, there is virtually no solid empirical evidence linking weather to voter participation. This paper provides an extensive test of the claim. We examine the effect of weather on voter turnout in 14 U.S. presidential elections. Using GIS interpolations, we employ meteorological data drawn from over 22,000 U.S. weather stations to provide election day estimates of rain and snow for each U.S. county. We find that, when compared to normal conditions, rain significantly reduces voter participation by a rate of just less than 1% per inch, while an inch of snowfall decreases turnout by almost .5%. Poor weather is also shown to benefit the Republican party’s vote share. Indeed, the weather may have contributed to two Electoral College outcomes, the 1960 and 2000 presidential elections.
