Changing Sides or Changing Minds? Party Identification and Policy Preferences in the American Electorate

Scholars have long debated the individual-level relationship between partisanship and policy preferences. We argue that partisanship and issue attitudes cause changes in each other, but the pattern of influence varies systematically. Issue-based change in party identification should occur among individuals who are aware of party differences on an issue and find that issue to be salient. Individuals who are aware of party differences, but do not attach importance to the issue, should evidence party-based issue change. Those lacking awareness of party differences on an issue should show neither effect. We test our account by examining individuals' party identifications and their attitudes on abortion, government spending and provision of services, and government help for African Americans using the 1992-94-96 National Election Study panel study, finding strong support for our argument. We discuss the implications of our findings both for the microlevel study of party identification and the macrolevel analysis of partisan change.

The Party Faithful: Partisan Images,Candidate Religion,and the Electoral Impact of Party Identification

We argue that the factors shaping the impact of partisanship on vote choice—“partisan voting”—depend on the nature of party identification. Because party identification is partly based on images of the social group characteristics of the parties, the social profiles of political candidates should affect levels of partisan voting. A candidate's religious affiliation enables a test of this hypothesis. Using survey experiments which vary a hypothetical candidate's religious affiliation, we find strong evidence that candidates’ religions can affect partisan voting. Identifying a candidate as an evangelical (a group viewed as Republican) increases Republican support for, and Democratic opposition to, the candidate, while identifying the candidate as a Catholic (a group lacking a clear partisan profile) has no bearing on partisan voting. Importantly, the conditional effect of candidate religion on partisan voting requires the group to have a salient partisan image and holds with controls for respondents’ own religious affiliations and ideologies.     

A Dynamic Model of Political Change Among Party Activists

In this article, we develop a dynamic model of aggregate attitudinal change among party activists in order to better understand the process by which new issues/cleavages divide major political parties. We build on existing research by developing a model of change that incorporates both conversion among continuing activists and the replacement of previous activists with newcomers who hold different views. We first explore such change among activists of the two major parties in the United States on the abortion issue. We then consider a number of alternative specifications of the model in order to generalize our findings. We conclude that conversion among continuing activists contributes in a substantial way to aggregate change among party activists by influencing the level of change, accelerating the change process, and sustaining change over time.     

Putting Politics First: The Impact of Politics on American Religious and Secular Orientations

Nearly all research on the political impact of Americans’ religious and secular orientations assumes that such orientations are exogenous to politics. Using multiwave panel and experimental data, we find that religious and secular orientations are endogenous to political orientations. In other words, religion and secularism are a consequence as well as a cause of politics. In showing this, we make three major contributions. First, we conceptualize and measure secular orientations in a new way—not just as the absence of religion, but also as an affirmative secular identity and positive commitment to secular principles. Second, our panel and experimental data allow for the most definitive test to date of whether political orientations exert a causal effect on religious and secular orientations. Third, we isolate the conditions under which politics affects religious–secular perspectives, thus identifying the mechanism that underlies political orientations.     

Extracorporeal membrane oxygenation in the forensic setting: A series of 19 forensic cases

Extracorporeal membrane oxygenation (ECMO) employs vascular cannulation and a gas exchange circuit to provide support to patients with severely compromised cardiopulmonary function. ECMO is often the last intervention taken before death and thus presents a unique challenge to medical examiners. This study describes the characteristics of decedents on ECMO at the time of death, including clinical indications, types of circuit configurations, causes and manners of death, gross findings at autopsy, and therapeutic complications. Files of a regional medical examiner office within an academic medical center were searched for the period between 2013 and 2019. Nineteen cases were identified with a median age of 36 years. The circumstances surrounding the initial presentation included: sudden death, trauma, substance abuse, homicide, therapeutic complication, work-related injury, drowning, and hypothermia. The underlying causes of death included injury-related, as well as respiratory and cardiac-related natural diseases. The time spent on ECMO varied from less than 1 h to 10 months. Complications encountered due to ECMO included cannulation site bleeding, pneumohemopericardium, retroperitoneal hematoma, limb ischemia, clotting, and cannula dislodgement. The patient population likely to receive ECMO has significant overlap with death circumstances likely to be reported to the medical examiner. As ECMO therapy has become increasingly available, it is of importance for medical examiners and death investigators to be familiar with the procedure as well as its limitations. Familiarity with ECMO and its sequelae allows for the proper documentation of postmortem findings and fosters an informed determination of the cause and manner of death.     

Value Priorities,Partisanship and Electoral Choice: The Neglected Case of the United States

A wealth of comparative scholarship indicates that a transformation in the value priorities of Western publics has been occurring during the last quarter century, and that value-based cleavages are increasingly coming to structure Western political behavior. The United States, however, has been conspicuous by its relative absence from this research enterprise. This paper attempts to partially fill this void in the literature by examining the impact of materialist-postmaterialist value priorities on American political behavior. Using data from the 1972 through 1992 American National Election Studies, we first compare the impact of the value-based cleavage on partisanship and presidential vote choice to that of other relevant sociodemographic variables. These analyses show that the effect of postmaterialism on American political behavior is not negligible. When the parties take distinct stances on postmaterial concerns, value type exerts a noticeable, though not overwhelming, influence on partisanship and vote choice. Further analyses show that the effect of value priorities on electoral behavior is mainly indirect, as they significantly shape attitudes on defense and racial issues, which in turn influence vote choice. Surprisingly, however, value type is not related to attitudes on cultural issues such as abortion and homosexual rights. Thus, although postmaterialism does have some relevance for American political attitudes and behavior, it does not seem to be pertinent to the cultural conflicts that are increasingly salient to American political life.     

Hair combing to collect organic gunshot residues (OGSR)

A protocol is presented for the collection and analysis of gunshot residues (GSR) from hair. A fine-toothed comb is used for collection of the residues. A small zip-closure bag serves as a container for both sample storage and extraction of the characteristic organic powder additives. The success of this residue recovery approach was tested on simulated shooters and victims using mannequin-supported human wig hair as well as on human shooters. Residues were collected from four weapons: a revolver and semi-automatic pistol, rifle and shotgun. One characteristic additive, nitroglycerin, was detected by capillary electrophoresis (CE) in the majority of the collection experiments.     

Party Polarization and Party Structuring of Policy Attitudes: A Comparison of Three NES Panel Studies

The conventional wisdom in the partisan change literature predicts that increasing party conflict on one issue agenda leads to a decline in party conflict on another agenda—a process called conflict displacement. We have argued that recent party politics in the United States has experienced conflict extension, with the Democratic and Republican parties in the electorate growing more polarized on cultural, racial, and social welfare issues, rather than conflict displacement. Here, we suggest that the failure of the literature to account for conflict extension results from incomplete assumptions about individual-level partisan change. The partisan change literature typically considers only issue-based change in party identification, which necessarily leads to the aggregate prediction of conflict displacement. This ignores the possibility of party-based change in issue attitudes. If party-based issue conversion does occur, the aggregate result can be conflict extension rather than conflict displacement. Our analysis uses data from the three-wave panel studies conducted by the National Election Studies in 1956, 1958, and 1960; in 1972, 1974, and 1976; and in 1992, 1994, and 1996 to assess our alternative account of individual-level partisan change. We show that when Democratic and Republican elites are polarized on an issue, and party identifiers are aware of those differences, some individuals respond by adjusting their party ties to conform to their issue positions, but others respond by adjusting their issue positions to conform to their party identification.
