One of the main supply-side explanations for women's underrepresentation in politics is the gender gap in nascent political ambition. While this has been examined in terms of electoral ambition, the aspiration to pursue non-electoral careers within parties has been overlooked. In our study, we therefore investigate whether both types of ambition – electoral and non-electoral – vary among young women and men participating in a key entry point for political careers in Western democracies: party youth wings. To do so, we surveyed almost 2,000 members of six centre-left and centre-right youth wings in Australia, Italy and Spain. We find that while, as expected, women in youth wings display lower levels of electoral ambition, they are almost as likely as men to express non-electoral ambition. Furthermore, and contrary to our expectations, we show that women in centre-right youth wings are no less interested in pursuing electoral and non-electoral political careers than women in centre-left ones. Our study thus provides new insights into the gendered nature of political ambition, highlighting that women's lower interest in electoral office does not necessarily reflect reduced interest in a political career.
