Scholars have long suggested that familial life can affect political behavior, and more recently, have found that fathering daughters leads men to adopt more liberal positions on gender equality policies. However, few have focused on the impact of fathering a daughter on congressional behavior, particularly in an era of heightened partisan polarization. Using an original dataset of familial information, we examine whether fathering a daughter influences male legislators’ 1) roll call and cosponsorship support for women’s issues in the 110th – 114th Congresses and 2) cosponsorship of bills introduced by female legislators in the 110th Congress. We find that once party affiliation is taken into account, having a daughter neither predicts support for women’s issues nor cosponsorship of bills sponsored by women. Our findings suggest there are limits to the direct effects of parenting daughters on men’s political behavior, and that scholars should remain attentive to institutional and partisan contexts.
