    Mobilized Interests: How Interest Groups Influence Member Perceptions of Politics
    (2024) Meli, Amy D; Miler, Kristina; Government and Politics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    In this project, I investigate how interest group mobilizations influence their members’ perceptions of government and politics. I theorize that some groups – especially issue advocacy nonprofits whose issues have been incorporated into the Democratic or Republican party platforms – use partisan strategies focused on electing the leaders who can help them move their policy agendas in Congress. Other groups, especially trade and professional associations, choose not to affiliate with a pollical party and instead build relationships with policymakers on both sides of the aisle so that they can move their policy agendas regardless of who is in office. I find that these two different policy strategies lead interest groups to communicate differently with their members, with partisan groups and issue advocacy nonprofits using more partisan and conflict-oriented language, while nonpartisan groups and associations use more pragmatic language. I find that these messages have effects on the people who read them. In a survey experiment, I find that independents and weak partisans who read pragmatic and bipartisan messages have warmer feelings towards the other party, while strong partisans have warmer feelings towards the other party when they hear partisan messaging. Notably, I find that these different approaches lead to varying effects on interest group members, including differences in levels of affective polarization and political efficacy. As professionals join their professional society and get more involved in their association’s activities, they have more trust in government, higher levels of internal and external efficacy, and warmer feelings towards those in the out party. Through interview research, I find that members are influenced by a number of factors, including the public policy training they receive from their interest groups, interactions they have with members of Congress and others in the political system, and messages members receive about how groups use bipartisan strategies to accomplish member goals. All of these stimuli are contributing factors to these effects.

    The population ecology of interest groups and counter-mobilization: reproductive rights organizations in the United States, 1920–1985
    (Cambridge University Press, 2024-01) Hightower, Tristan M.
    This research note builds upon a number of important articles published in a variety of outlets concerning the population ecology of interest groups. Importantly, Lowery and Gray (1995), Nownes (2004), and Nownes and Lipinski (2005) empirically demonstrated the dependence on the density of pre-existing, similar groups when predicting new group formations. In this letter, I add to this research by modeling the density of ideologically divergent reproductive rights groups as well as offer supporting evidence for the popular Energy-Stability-Area model. The former is a novel consideration in the field of population ecology which primarily examines ideologically similar groups. I show that density dependence is at play among these polarized groups. I also provide insight into counter-mobilization movements of group formation by empirically demonstrating which groups are initial movers versus reactionary formers. In doing so, I raise important questions for researchers concerned with the emergence, longevity, and impact of interest groups over long periods of time. Finally, this research provides some insight into the expectations of group formation behavior in light of the landmark Dobbs decision.
