In recent years, a number of scholars have taken parties and partisanship as objects of normative theorizing. They posit partisanship as a fundamentally democratic practice and develop a model of what partisans can do at their best to contribute to liberal democracy.However, the standards the literature puts forth remain insufficiently specified to serve as If parties fulfil such irreplaceable functions, this also implies that their failures will have consequences for the vitality of modern democracy (Goodin 2008). While a vast literature documents the democratic performance of political parties, party scholars have been reluctant to engage with contemporary democratic theory. This has resulted in a body of work that is generally under-theorized, and which tends to overlook some of the central affective and symbolic functions that parties perform (van Biezen and Saward 2008). This paper responds to these challenges with a model of democratic partisanship amenable to empirical study. My starting point is a recent body of democratic theory that takes partisanship as its main object, and from which I derive a number of standards for democratic partisanship. For the purpose of this article, I define partisanship as the routinized practices and discourses of the supporters, members and leaders of a particular party in support of a shared conception of the public good. 2 Partisanship is democratic when these routinized practices and discourses contribute to liberal democracy, understood as a system of limited representative government that ensures both popular self-rule 2 As emphasized by White and Ypi, partisanship conceived as the "collective will of partisans" can exist without a party structure at its centre (White and Ypi 2016, 23). For the purpose of this article, I focus on those more easily identifiable communities that find an organizational expression and are thus tied together by party support, membership or leadership.Lise Herman, Forthcoming, American Political Science Review 3 and respect for minority rights. The set of specific indicators that this article develops serves to empirically evaluate the democratic merits of partisan discourse more specifically.In what follows, I will first discuss the lack of engagement of party studies with democratic theory, and how existing theories of partisanship are either insufficiently refined or insufficiently comprehensive to empirically evaluate the democratic merits of partisan discourses and practices on their basis. In the second part of this paper, I further conceptualize these theories and focus on two main characteristics that the literature ascribes to democratic forms of partisanship:cohesiveness and respect for political pluralism. Starting from these two general concepts, I derive a series of more specific indicators that can serve to evaluate the extent to which the discourses of real-world partisans meet these normative ideals. The last section of the paper illustrates how this theoretical framework can be applied in empirical studies of...
