Twenty years ago, Pippa Norris and Joni Lovenduski published the classic work Political Recruitment: Gender, Race and Class in the British Parliament (1995), one of the most comprehensive accounts of legislative recruitment thus far. Seeking to explain the social bias evident in legislatures worldwide, Norris and Lovenduski focused on the central role of political parties, arguing that the outcome of parties’ selection processes could be understood in terms of the interaction between the supply of candidates wishing to stand for office and the demands of party gatekeepers who select the candidates. Indeed, in most countries, political parties control not only which candidates are recruited and selected, but also are the central actors involved in adopting and implementing candidate selection reforms such as gender quotas. Yet, two decades later, systematic studies of the “secret garden” of candidate selection and recruitment have been few and far between in the gender and politics literature. It therefore seems a particularly appropriate time to revisit the core preoccupations, puzzles, and challenges that remain in the field of gender and political recruitment.
