Face mask mandates: Unilateral authority and gubernatorial leadership in US states.

During the first year of the COVID‐19 pandemic in the United States, the coordination and cooperation between the federal government and the states failed. American governors were thus tasked with making critical public health policy choices—under extreme uncertainty—with varying institutional capacities, partisan pressures, and state demographic differences. Yet most of the nation's governors chose to impose a face covering or mask mandate to limit the spread of cases. We collected each governor's executive order that mandated the conditions under which their residents would be required to wear a mask and employed a sentiment analysis program to extract key qualities of crisis leadership communication. Our analyses provide insights into the institutional and partisan factors that determined a face mask mandate as well as the institutional, demographic, and leadership communication qualities that affected the total number of cases per capita in the states. Our findings have important implications for post‐pandemic policy recommendations with respect to the effectiveness of policies that seek to lower the transmission of viruses in public spaces and the characteristics of impactful public health messaging by government leaders.
