We know that women politicians are harassed by constituents to a greater extent than men, but we know less about why this difference exists. This study tests potential drivers of hostility against women politicans using an original survey experiment with 7,500 respondents in the United States and Sweden. First, I test whether constituents hold more lenient attitudes toward hostility directed at women than men, which would make hostility in messages targeting women representatives more likely. Second, I test whether constituents prefer to direct their complaints to women, which would increase the risk of hostility by generating a higher number of angry contacts. Results from both countries show a preference for directing complaints to women representatives over men, but no evidence of more leniency toward hostility directed at women.
