Electoral Studies 36: pp 28-38. [ Link to paper. | Local link to paper. ]
Abstract: What are the effects of a mobilized party base on elections? I present a new behavioral measure of the enthusiasm gap in a set of American elections to identify how the turnout rate of the party faithful varies across different contexts. I find that the advantaged party can see its registrants turn out by four percentage points more than the disadvantaged party in some elections, and that this effect can be even larger in competitive House districts. I estimate the net benefit to party vote share of the mobilized base, which is around one percentage point statewide, and up to one and one half points in competitive House contests. These results suggest that the partisan characteristics of an election have consequences not just for vote choice, but for the composition of the electorate.

Political Science Research and Methods 1 (1): pp 91-116. [ Link to paper. ]
Abstract: What effect does moving to all-mail elections have on participation? On one hand, all registered voters automatically receive a ballot to return by mail at their convenience. On the other hand, the social aspect of the polling place, and the focal point of election day, is lost. Current estimates of the effect of all-mail elections on turnout are ambiguous. This article offers an improved design and new estimates of the effect of moving to all-mail elections. Exploiting cross-sectional and temporal variation in county-level implementation of all-mail elections in Washington State, we find that the reform increased aggregate participation by two to four percentage points. Using individual observations from the state voter file, we also find that the reform increased turnout more for lower-participating registrants than for frequent voters, suggesting that all-mail voting reduces turnout disparities between these groups.

Abstract: Although the secret ballot has been secured as a legal matter in the United States, formal secrecy protections are not equivalent to convincing citizens that they may vote privately and without fear of reprisal. We present survey evidence that those who have not previously voted are particularly likely to voice doubts about the secrecy of the voting process. We then report results from a field experiment where we mailed information about protections of ballot secrecy to registered voters prior to the 2010 general election. Consistent with our survey data, we find that these letters increased turnout for registered citizens without records of previous turnout, but did not appear to influence the behavior of citizens who had previously voted. The increase in turnout of more than three percentage points for those without previous records of voting is notably larger than the effect of a standard get-out-the-vote mailing for this group. Overall, these results suggest that although the secret ballot is a long-standing institution in the United States, beliefs about this institution may not match the legal reality and that providing basic information about ballot secrecy can affect the decision to participate to an important degree.

Public Opinion Quarterly 77 (2): pp 474-496. [ Link to paper. | Local link to paper. ]
Abstract: Should people discuss their vote choices with others? On one hand, many people argue that openly deliberating with others can lead to better decision-making. On the other hand, institutions like the secret ballot imply that keeping these choices secret has value, perhaps as a means of insulating people from unwanted social pressures. This paper examines public attitudes about whether it is best to discuss one’s choices with others or treat them as personal matters. We find that the American public is evenly divided on this issue. We also find that those who are least confident in their political capabilities—those who arguably could benefit most from deliberating their vote choices—are most likely to say that choices should be treated as personal matters. Our findings have implications for understanding the role of political deliberation in the United States.

Political Communication 30 (4): pp 521-547. [ Link to paper. ]
Abstract: Scholars do not usually test for the duration of the effects of mass communication, but when they do, they typically find rapid decay. Persuasive impact may end almost as soon as communication ends. Why so much decay? Does mass communication produce any long-term effects? How should this decay color our understanding of the effects of mass communication? We examine these questions with data from the effects of advertising in the 2000 presidential election and 2006 sub-national elections, but argue that our model and results are broadly applicable within the field of political communication. We find that the bulk of the persuasive impact of advertising decays quickly, but that some effect in the presidential campaign endures for at least six weeks. These results, which are similar in rolling cross-section survey data and county-level data on actual presidential vote, appear to reflect a mix of memory-based processing (whose effects last only as long as short-term memory lasts) and on-line processing (whose effects are more durable). Finally, we find that immediate effects of advertising are larger in sub-national than presidential elections, but decay more quickly and more completely.

Election Law Journal 11 (4): pp 358-379. [ Link to paper. ]
Abstract: Alvin Greene surprised the political world when he handily defeated Vic Rawl for the United States Senate nomination in the 2010 Democratic Primary in South Carolina. Greene had not run a campaign during the primary and appears to have been almost completely unknown prior to his surprise victory. Greene's win over Rawl, who had served eight years in the South Carolina House, was previously a circuit judge, and had in fact run a legitimate primary campaign, raised a variety of questions about how Greene could have managed to generate so much voter support. In light of lingering concerns that Greene's victory was due to malfeasance of some sort, we analyze both ballot-level and precinct-level voting data with an eye toward determining whether the 2010 Democratic Senate Primary in South Carolina appears problematic. We find that voting patterns in Greene's victory over Rawl do not exhibit unusual peculiarities and in fact are consistent with the types of regularities observed in American elections. Rawl is white and Greene is black, and this difference played a major role in Greene's victory. While this victory may have been a surprise, voters in the Greene vs. Rawl primary appear in retrospect to have behaved similarly to voters in other elections in the United States, thus lending legitimacy to Greene's win.

American Political Science Review 106 (4): pp 720-741. [ Link to paper. ]
Abstract: Are citizens competent to assess the performance of incumbent politicians? Observational studies cast doubt on voter competence by documenting several biases in retrospective assessments of performance. However, these studies are open to alternative interpretations because of the complexity of the real world. In this article, we show that these biases in retrospective evaluations occur even in the simplified setting of experimental games. In three experiments, our participants (1) overweighted recent relative to overall incumbent performance when made aware of an election closer rather than more distant from that event, (2) allowed an unrelated lottery that affected their welfare to influence their choices, and (3) were influenced by rhetoric to give more weight to recent rather than overall incumbent performance. These biases were apparent even though we informed and incentivized respondents to weight all performance equally. Our findings point to key limitations in voters' ability to use a retrospective decision rule.

World Politics 62 (2): pp 177-220. [ Link to paper. ]
Abstract: One compelling justification for democracy is that public officials can be held accountable. Elected representatives who betray the public trust by extracting excessive rents are vulnerable to electoral retribution with loss of office. Perhaps surprisingly, however, evidence from a variety of countries documents that elected officials who are charged with or convicted of criminal wrongdoing are typically reelected rather than repudiated by the electorate. This finding resonates with studies that suggest in various ways that political accountability may be realized only imperfectly even in well-established democracies, either because voters hold politicians responsible for things patently not under their control or because voters fail to take unresponsive or malfeasant representatives to task. In this article we argue that electoral retribution for allegations of criminal behavior by national legislators hinges on the dissemination of relevant information by the mass media. Without media reports that inform voters of judicial allegations that public officials have engaged in criminal activities, the electorate's response to charges of malfeasance is one of apparent indifference. We thus identify the informational environment as a critical factor that affects the ability of voters to hold politicians accountable.

Election Law Journal 9 (1): pp 41-62. [ Link to paper. ]
Abstract: Democratic presidential candidate Barack Obama was the beneficiary of a nationwide swing in 2008: he outperformed the 2004 Democratic presidential nominee John Kerry across nearly the entire country. Nonetheless, there was substantial local variation in the degree to which support for Obama exceeded the support given to Kerry four years earlier. With this in mind we show that county-level variation in (1) economic conditions, (2) the human cost of the wars in Afghanistan and Iraq, and (3) the sizes of African-American and Latino populations account for a major share of the local variation in the 2008 pro-Obama swing. Our estimates suggest that the downturn in the housing and mortgage markets and the wars in Afghanistan and Iraq greatly advantaged Obama, increasing his national vote share by at least 5.8 percentage points. We also find that, within Southern states but not elsewhere in the country, the degree to which Obama outperformed Kerry across individual counties was strongly increasing in the size of African-American population.

Quarterly Journal of Political Science 4 (3): pp 229-249. [ Link to paper. | Local link to paper. ]
Abstract: We estimate the effect of candidate appearance on vote choice in congressional elections using an original survey instrument. Based on estimates of the facial competence of 972 congressional candidates, we show that in more competitive races the out-party tends to run candidates with higher quality faces.We estimate the direct effect of face on vote choice when controlling for the competitiveness of the contest and for individual partisanship. Combining survey data with our facial quality scores and a measure of contest competitiveness, we find a face quality effect for Senate challengers of about 4 points for independent voters and 1-3 points for partisans. While we estimate face effects that could potentially matter in close elections, we find that the challenging candidate's face is never the difference between a challenger and incumbent victory in all 99 Senate elections in our study.

NBER Working Paper w19080. [ Link to paper. ]
Abstract: Partisanship seems to affect factual beliefs about politics. For example, Republicans are more likely than Democrats to say that the deficit rose during the Clinton administration; Democrats are more likely to say that inflation rose under Reagan. What remains unclear is whether such patterns reflect differing beliefs among partisans or instead reflect a desire to praise one party or criticize another. To shed light on this question, we develop a model of partisan survey response and report two experiments that are based on the model. The experiments show that small payments for correct and ``don't know'' responses sharply diminish the gap between Democrats and Republicans in responses to ``partisan'' factual questions. Our conclusion is that the apparent gulf in factual beliefs between members of different parties may be more illusory than real.
- Hill, Seth J. "Changing Votes or Changing Voters: How Candidates and Election Context Swing Voters and Mobilize the Base"
[ Local link to paper. ]
Abstract: Candidates attempt to mobilize supporters and persuade swing voters to win elections. I derive theoretical propositions that suggest that the influence of swing voters depends upon change in the candidates across elections. The consequences of changes in composition depend upon the relative balance of campaign expenditures. I estimate a Bayesian hierarchical model on Florida electoral data for house, governor, and senate contests. Swing voters contribute on average 4.1 percentage points to change in party vote shares, while change in turnout influences outcomes by 8.6 points. The effect of swing voters is increasing in the divergence between the Democrat and Republican candidates, and candidates increasingly benefit from the votes of occasional voters as the relative balance of campaign spending increases in their favor. More broadly, I show that the effects of swing voters and turnout are not constant features of American elections. Instead, these effects vary across time and space in ways that can be explained by candidates and context.
- Hill, Seth J. "Primary Electorates and Member Ideology in the U.S. House"
[ Local link to paper. ]
Abstract: One common explanation for the divergence between what members of Congress do and what the public as a whole would prefer is the polarized preferences of the citizens who participate in primary elections. If candidates must appeal both to a primary electorate with far-from-center policy preferences and a general electorate with more moderate policy preferences, candidates may diverge from the policies they would support if they only had to win the general election. Despite the appeal of this argument, most empirical evidence on the effects of primaries finds small to no effects. I use survey data with validated turnout and a hierarchical model to estimate the preferences of Democratic and Republican primary electorates and the general electorate in each House district in 2010. After showing that the primary electorate diverges from the general electorate in every House district, I find that primary and general electorate preferences have about equal influence on ideology in Congress. I provide evidence against endogeneity using vote returns in the 2012 Texas senatorial primary. My results suggest that the effect of primary elections depends upon the voters who choose to participate.

[ Local link to paper. ]
Abstract: While it is widely agreed that Congress has polarized over the past 40 years, there is considerable disagreement about the extent of public polarization and its connection to congressional polarization. We present the first estimation of time series of polarization using the same method on the most comprehensive data for both the public and the Senate. With statistics of various definitions of polarization, we find little increase in the dispersion of views in the public from 1956 to 2012, but do find an increase in ideological sorting starting around 1980. The two time series bear little resemblance to one another with respect to divergence. Further, while congressional sorting exceeds that in the public today, we find that Congress has always been unrepresentative of the public. These results suggest that it is unlikely that changes in public preferences alone explain the widening gulf between the two parties in Congress.

[ Link to paper. ]
Abstract: All survey methodologies have weaknesses, some known and others unknown. Given that there are no "true" targets against which to assess the political marginal distributions about which we care, the decision to use any survey methodology must be met with caution and full disclosure about the strengths and weaknesses of the method, and how it might affect the results. In this paper, we assess the differences among several national surveys in terms of demographics, marginals on political variables, and ideological constraint among respondents at varying levels of political awareness. Our results suggest that Polimetrix's sample matching technique, used in the 2006 Cooperative Congressional Election Study, seems to produce Internet samples that look more similar to existing RDD phone surveys than to multi-stage probability face-to-face surveys, but surprisingly, many of the discernible differences are not large in size. We conclude that a mildly biased but large Internet survey can produce more reliable estimates than an unbiased but small survey (because of the random error due to the small samples). When matters of cost are factored in, the large, biased sample becomes even more appealing to researchers with limited budgets. The question about Internet samples (even matched samples such as those generated by Polimetrix) remains, however, whether the ignorability assumption holds such that the people who take surveys online behave the same way as those who do not, or more precisely, as those who take phone or in-person surveys.
