This chapter studies the voting behavior of members of the House of Representatives. If the presence of Fox News in a district shapes potential candidates’ perceptions about district party composition and the constituency’s electoral preferences, there are good chances that the same can be said of sitting House members. Here, of course, the expectation is not about how these perceptions affect the decision to run for office; instead, they affect decisions about how to perform so as to stay in office. Much like potential candidates, sitting members of Congress have to make inferences about what their constituents want. Typically, they make these inferences based on their perceptions of the partisan composition of their district, among other considerations. If sitting members are influenced like potential candidates, Fox News might shift their perceptions in the direction of thinking their district is more right-leaning. Alternatively, based on our evidence from Chapter 3, they might feel more vulnerable to challenges from potential candidates to their (ideological) right. In either case, a reasonable expectation, which we find evidence for, is that member roll call votes will move in a rightward direction, especially among Democrats representing more competitive districts.

In this chapter, we investigate whether Fox News’ presence in districts shaped the competitive electoral landscape by influencing potential candidates’ perceptions about the partisan make-up of the constituency in the district and shaping their perceived chances of winning or losing. Specifically, in this chapter, we test whether the entry of Fox News created the perception of a rightward shift in district party composition among potential Republican candidates considering a run in the district. We find that in districts with more Fox News availability, high-quality potential Republican candidates were more likely to challenge Democratic incumbents, especially if the districts were closely competitive.

In this concluding chapter, we review our findings in the context of our initial pre-analysis plan and discuss the limitations of our studies. We then analyze the implications of our study and findings for their scholarly contributions and discuss next steps for future research. We conclude with a discussion of the normative implications of our findings. Despite the hubbub about Fox News being a bull-in-the-china shop, its effects on politicians were contingent on the context of the district they represented. Even if its effects were circumscribed, our evidence shows that the consequences were real. The implications of our findings are twofold. On the one hand, it throws some cold water on the popular notion that Fox News was a right-wing bulldozer that pulled American politics uniformly in a conservative direction. On the other hand, it makes clear that standard theoretical models of congressional behavior are founded on an assumption that, while useful, is most certainly flawed. Namely, politicians are not fully informed rational calculators. Politicians are people.

This chapter focuses on collective representation, examining whether Fox News affects how the American public is represented. Chapter 5 revealed Fox News effects on dyadic representation; we cannot assume similar effects on collective representation. Yet, in some ways, the path by which Fox News would affect collective representation is clearer than at the district-level. Because Fox News is a national outlet with a wide following, it could affect collective representation through agenda-setting. If many people across many districts regularly watch Fox News, it may draw the attention of both legislators and constituents to the same set of issues. To test for Fox News effects on collective representation, we examine whether the presence of Fox produced different policy outcomes than would have occurred in its absence. We simulate a world where Fox News does not exist in any member’s district and then compare it to the actual behavior of members of Congress given the observed levels of Fox News. The results suggest a boost for Republican policies in four of the six Congresses we examined. However, the effects are only statistically significant for one Congress, the 108th (2003–2004).

This chapter begins with a description of the arrival and proliferation of Fox News across the United States during its early years and concludes with a description and some analyses of Fox News’ content. Both demonstrations are critical to our case. The former is required because our identification strategy requires that we satisfy the assumption that the Fox News rollout was as-if random – or haphazard – in the sense that it is not related to political factors capable of shaping House members’ behavior. The latter is important for both our empirical evidence and theoretical arguments. First, if we expect the arrival and presence of Fox News to have a unique influence on elite political behavior, it is important to demonstrate whether and to what degree Fox News’ content is different from other networks. Second, examining Fox News’ content can tell us something about the mechanisms for its effects or the process by which it shapes the attitudes and behaviors of political elites.

This chapter sets up our main research question, which is what effect, if any, did the arrival and proliferation of Fox News have on US politicians? It summarizes the history of Fox News and describes the natural experiment created by the haphazard rollout of Fox News. It goes on to summarize the scholarly literature on media effects and, specifically, how little of it focuses on the behavior of politicians. In turn, it summarizes the scholarly literature on members of Congress and how little of it focuses on the media. It then explains our open science approach.

This chapter highlights the role media play in political accountability. If Fox News’ entry and presence can shape candidate and member perceptions about what districts want (as we saw in Chapters 3 and 4), can Fox News also shape how responsive representatives are to constituents’ policy preferences? This responsiveness to the district – also known as dyadic representation – is the subject of our examinations in Chapter 5. To test this question, we quantify the degree to which representatives’ voting behavior diverges from what it should be (if they were faithfully following district public opinion). Here we find, once again, that Fox News increases the tendency for Democratic members in marginal districts to “move rightward” in response to rising Fox News availability in the district. In this analysis, our measures reflect the tendency for Democrats in right leaning districts to err on the conservative side of the median voter in their district, and that tendency gets worse as district-level availability of Fox News increases.

This chapter reviews research at the intersection of psychology and political science that studies how people form political beliefs. We discuss the degree to which people’s motivations shape the beliefs that they form, paying particular attention to the extent to which people’s political beliefs are generated through reflection. Both individual differences and situational factors affect the extent to which people are reflective in political domains. As always, more questions remain than researchers have answered, and we conclude with some thoughts about the most pressing ones that future research should tackle.
