This article sheds light on the factors that pave the way from voter abstention to voter turnout based on extensive research of tweets on national and local elections in Turkey. We find that the negative campaign strategy of the incumbent and the fact that the campaigning process has taken place on a very uneven playing field have triggered a set of emotions, primarily moral outrage and anger among the electorate, which have the power to change voting patterns in a significant way. The effect of negative campaigning on expressive voting was further enhanced by the pulling effect of the candidates and their public supporters and endorsements. We found that other, competing explanations of political outcomes are secondary to the mechanisms above.

We explore mediated representations of parties' campaign interactions in multi-party systems. Actors in multi-party systems can engage with different actors on multiple issues. One crucial aspect of such engagement is the element of negativity—voicing criticisms of other actors' actions and policy proposals. This contribution argues that the media systematically exaggerate patterns of negativity based on issue ownership structures, such that attacks originating from or targeting issue owners are significantly more likely to be covered. We analyze a broad sample of news content from the 2013 Austrian national election campaign with generalized exponential random graph models to capture the complexities of mediated campaign negativity in a multi-party system while controlling for non-mediated campaign negativity. The results show that issue owners are more likely to be featured as attackers and targets in owned policy domains, suggesting a violation of the normative ideal of a fair representation of campaign interactions.

Little comparative evidence exists about what causes candidates to use negative campaigning in elections. We introduce an original comparative data set that contains experts’ information about campaigning strategies of 172 candidates competing in 35 national elections worldwide between June 2016 and May 2017. Analyses reveal several trends: incumbents run positive campaigns but are especially likely to attract attacks, candidates far from the ideological centre are more likely to ‘go negative’, candidates tend to attack frontrunners and rivals that are far from them ideologically, but they also engage in a logic of attack reciprocity with selected candidates. The comparative nature of the data also allows us to test whether variations in the context affect the use of campaign negativity; we find that the context matters mostly indirectly, by altering the effects of individual characteristics.

This article supplements and further develops the almost exclusively American literature on the determinants of negative campaigning by analyzing the tone of the Danish parties’ election campaigns. It concludes that proximity to governmental power matters, as oppositional parties are more negative than incumbents. This is comparable to the American experiences. The prospect of electoral failure, however, does not affect the tone the same way as poor poll standings do in the US. Moreover, it is suggested that future studies of negativity might consider how different party organizations affect the campaign tone; at least this study finds indications that parties with large proportions of party identifiers are slightly more negative than other parties. Finally, it is found that parties campaign differently in different channels of communication; that is, they are generally more negative in channels that allow direct interaction among politicians. This finding poses the question whether some channels are better empirical sources for studies of negativity than others, which is addressed in the closing section of the article.
