To allow researchers to investigate not only whether a paper’s methods are theoretically sound but also whether they have been properly implemented and are robust to alternative specifications, it is necessary that published papers be accompanied by their underlying data and code. This article describes experiences and lessons learned at the Quarterly Journal of Political Science since it began requiring authors to provide this type of replication code in 2005. It finds that of the 24 empirical papers subjected to in-house replication review since September 2012, only four packages did not require any modifications. Most troubling, 14 packages (58%) had results in the paper that differed from those generated by the author’s own code. Based on these experiences, this article presents a set of guidelines for authors and journals for improving the reliability and usability of replication packages.

Political scientists have devoted vastly more attention to general presidential elections than to party nominations for president. This emphasis might be reasonable if parties could be counted on to nominate generic representatives of their traditions. But it is clear that they cannot. Since the party reforms of the 1970s, regulars like Bill Clinton, Bob Dole, and Al Gore have sometimes won fairly easy nominations, but outsider candidates like Jimmy Carter and Howard Dean have made strong runs or even won. 2016 has produced extremes of both types: ultimate regular Hillary Clinton on the Democratic side and far outsider Donald Trump on the Republican side. It seems, moreover, that party regulars are having more difficulty in recent cycles than they did in the 1980s and 1990s. There is therefore some urgency to the question: when and why do party regulars tend to win nominations?

We examine this question from the point of view of two well-known studies, Nelson Polsby’s Consequences of Party Reform and our own, The Party Decides. The former explains why incentives built into the reformed system of presidential nominations make outsider and factional candidates like Trump likely. The latter argues that, following the factional nominations of the 1970s, party leaders learned to steer nominations to insider favorites. This article uses the logic of these studies to argue that major trends over the past two decades – the rise of new political media, the flood of early money into presidential nominations, and the conflict among party factions – have made it easier for factional candidates and outsiders to challenge elite control of nominations.

The 2016 Republican presidential nomination challenges arguments about political party insiders’ influence on the outcome. This article argues, first, that party insider influence is conditional on the participation, coalescence, and timing of party stakeholders behind a front-runner during the invisible primary, and second, that party insider influence has probably declined since the 2000 presidential election. Data on endorsements by elite elected officials in open presidential nominations from 1984 to 2016 show that party insiders’ participation and convergence of support behind the front-runner is less extensive than what was found by Cohen, Karol, Noel, and Zaller (2008), though the data sets differ. Party insiders participate and unify more readily when the party coalition is stable and there is a candidate in the race who has demonstrable national support. Party elites remain on the sidelines when the party coalition is divided or when there is uncertainty about the appeal of candidates (Ryan 2011; Whitby 2014). The potency of insider endorsements likely has declined with the rise of social media, the changing campaign finance landscape, and the reemergence of populism in each party.

This essay corrects and updates one that was originally published in Qualitative & Multi-Method Research and, in a condensed version, in three other APSA Organized Section newsletters. Our research into IRB policy has shown that many political scientists are not familiar with some of its key provisions. The intent of the essay is to increase awareness of the existing policy’s impact on political scientific research and, in particular, on graduate students and junior faculty. We remain concerned that at present, faculty are leaving discussions of research ethics to IRBs (and their counterparts worldwide), whereas these Boards largely focus on complying with the regulatory details of governmental policy. Even though this essay seeks to clarify the latter, we remain convinced that research ethics ought to be vigorously taken up within disciplinary and departmental conversations.

While the party decides theory explains the outcomes of past nomination battles for president, this year in the Republican presidential contest party insiders failed to anoint a standard bearer. Who decides when the party elites don’t? In 2016, it was America’s authoritarian voters. And their candidate of choice, Donald Trump, is anathema to party leaders. I argue that Trump’s rise is in part the result of authoritarian voters’ response to his unvarnished, us-versus-them rhetoric. The failure of Republican Party insiders to coalesce behind one candidate opened the door for Trump. Authoritarian-driven partisan polarization (Hetherington and Weiler 2009), increasing fear of real and imagined threats, and terrorist incidents abroad and at home provided the fuel for Trump’s campaign. And Trump’s message and manner ignited that fuel, propelling him to the Republican nomination for president.

Few empirical studies suggest that fictional stories can influence political opinions. Nonetheless, in this study I demonstrate the relevance of Harry Potter consumption to oppositional attitudes toward Donald Trump and his worldview. Using multivariate observational models and panel data from 2014 to 2016, results suggest that the lessons of the Harry Potter series have influenced levels of opposition to punitive policies and support for tolerance of groups considered outside the American mainstream. Further, they predict public reactions to Donald Trump above and beyond their influence on policies consistent with his views.

An emerging consensus suggests that women are underrepresented in government because of biases in the recruitment process instead of biases at the ballot box. These results, however, are largely for legislative offices, and research suggests that “male” characteristics are generally associated with executive positions like the presidency. At the same time, some research demonstrates social desirability masks gender biases against women who seek the highest office in the land. We use the historic candidacy of Hillary Clinton to examine if she faces hidden biases in either the primaries or the general election. Two different methods for uncovering hidden biases embedded in national surveys demonstrate small hidden biases that are likely electorally inconsequential.

Across the social sciences, growing concerns about research transparency have led to calls for pre-analysis plans (PAPs) that specify in advance how researchers intend to analyze the data they are about to gather. PAPs promote transparency and credibility by helping readers distinguish between exploratory and confirmatory analyses. However, PAPs are time-consuming to write and may fail to anticipate contingencies that arise in the course of data collection. This article proposes the use of “standard operating procedures” (SOPs)—default practices to guide decisions when issues arise that were not anticipated in the PAP. We offer an example of an SOP that can be adapted by other researchers seeking a safety net to support their PAPs.
