... While in the short term, these new service parties effectively mobilized voters on behalf of national elections and national party objectives, they also produced a more "hollow" party structure, top-heavy and ill-connected to the daily lives and concerns of their voters (Schlozman and Rosenfeld 2024). These effects had, to some degree, been foreshadowed by the call for a "more responsible two-party system" led by the American Political Science Association in the 1940s (Committee on Political Parties 1950). ...

... Si bien hoy lo relacionamos con el racismo y el conservadurismo, en sus orígenes estaba atado a movimientos que iban contra el statu quo imperante. En su larga historia, siguió una trayectoria curiosa: uno podría argumentar que fue de movimiento a partido establecido y luego a partido capturado por movimientos, pero desplazándose al otro lado del espectro ideológico de quienes le dieron su primer impulso (McAdam & Kloos, 2016;Roberts, 2018;Schlozman & Rosenfeld, 2024). ...

... The UCLA school of parties (especially Bawn et al., 2012) highlights the importance of "policy demanders"-including donors, activists, interest groups, and even friendly partisan media-in determining candidate selection outcomes. In part because US nominations are comparatively inclusive and decentralized (Hazan and Rahat, 2010;Cowburn and Kerr, 2023), formal party organizations have been "hollowed out" (Schlozman and Rosenfeld, 2019), transferring power from electability-focused formal structures toward comparatively non-centrist and policy-oriented "informal party organizations" (Masket, 2009). Alignment with these groups can help candidates secure the nomination in several ways. ...

... Combining these arguments with an analysis of social interactions and the geographic distribution of opinions leads to the conclusion that greater national (as opposed to local) salience leads to increased po-larization and instability in larger-scale elections. These results parallel the situation in the United States, in which "hollowed-out," "top-heavy" parties that used to be largely local have led to increasingly unstable national elections and non-competitive local offices [16]. ...

... Given the radical nature of libertarian ideology, pragmatic party elites within mainstream right-wing parties should have an incentive in resisting libertarian policy demands so as not to antagonise voters, as shown with the party-political repudiation of other radical movements that have risked alienating mainstream parties from centrist voters, such as the anti-war or Occupy movements (Schlozman, 2015). But there have been times when the libertarian movement's influence has helped to significantly change mainstream party policy, such as with the UK Conservative Party in 1975 (e.g. ...
