The US Congress is unrepresentative of the people it serves, and reforming campaign finance law may be a path toward a more representative institution. We examine public opinion toward allowing candidates to use campaign funds for child care, theorizing gender conditions support due to the unequal burden child care places on women. Using an experiment, we find people are more supportive of candidates using campaign funds for child care when the hypothetical candidates are women. Women respondents are especially likely to vary their support for the policy based on candidate gender. This project is the first to explore public support for allowing candidates to use campaign funds for personal expenses, contributing to our understanding of support for reform that could transform the types of candidates willing to run.
