Donald Trump's surprise win in 2016 galvanized once-politically quiescent women and jolted those who had believed second-wave feminist victories were enduring. This “resistance” drew on two potent forces: the passion of the newly awakened, primarily grassroots participants; and the organizing experience of professionals and institutions determined to channel that passion into sustainable electoral and policy gains. The movement expanded beyond the political to encompass the social and cultural spheres and gave women of color a place in the spotlight. As women ran for national, state, and local office in record numbers, the #MeToo movement toppled men who once harassed with impunity. Record numbers of women won in the 2018 midterms, retaking the U.S. House of Representatives for the Democrats, and six women declared their candidacy for president in 2020. But it remains unclear whether these gains will be lasting and overcome remaining ambivalence about women and power.
