This paper uses the Mexican case to explore outstanding questions in the connection between women’s descriptive representation (that is, women’s numerical presence in the legislature) and women’s substantive representation (that is, women’s policy interests). Consistent with previous work in Latin America, I find that electing women indeed diversifies the legislative agenda, and that female legislators –rather than male legislators– author proposals with feminist understandings of women’s rights and roles. These trends are robust across Mexico’s ideologically-organized political parties, indicating that feminist advocates should care about electing leftists and women. That is, rightist women are still more progressive than rightist men. Finally, I make a case for unpacking the relationship between women, hearth, and home, and eliminating the conflation of “women’s interests”with children
