Moral rhetoric presents a strategic dilemma for female politicians, who must navigate stereotypes while appealing to copartisan voters. In this article, we investigate how gender shapes elite moral rhetoric given the influence of partisanship, ideology, gender stereotypes, and moral psychology. Drawing on moral foundations theory, we examine how female and male representatives differ in their emphasis on the five foundations of care, fairness, authority, loyalty, and purity. Using the Moral Foundations Dictionary, we analyze a corpus of 2.23 million tweets by U.S. Congress members between 2013 and 2021. We find that female representatives are more likely to emphasize care and less likely to emphasize authority and loyalty than their male peers. However, when subsetting by party, we find that gender effects are most pronounced among Democrats and largely negligible among Republicans. These findings offer insight into the rhetorical dynamics of political leadership at the intersection of gender and partisan identities.
