The internet is part of people’s daily lives, and social networking sites (SNSs) may provide insights into how people perceive government actions. The present case study contributes to the debate concerning SNSs as an alternative communication tool between citizens and politicians in terms of information about the policies that rule citizens’ lives. To reach this goal, we explored the role of Twitter sentiment analysis as a means of monitoring reactions to Reactiva Perú, a program implemented by the Peruvian Government in response to the COVID-19 economic crisis. The findings suggest that SNSs may become an alternative source of information for policymakers to capture citizens’ reactions to implemented policies. Implications and possible strategies are discussed at an empirical level.
