Abstract- Does internet access have an effect on the electoral penalty for corruption cases? Several studies have examined the effect of social media and the internet on electoral outcomes. However, there has been limited research on how access to broadband internet affects the electoral penalty following well-known corruption cases. This study aims to investigate the role of internet access in the electoral success of one of the two largest political parties in Spain, the Popular Party (PP), after the trials of the corruption scandal known as the Gürtel case in 2016. To establish the causal effect of broadband internet access on the PP vote, I apply a difference-in-differences methodology, leveraging the exogenous expansion of broadband internet access between 2013 and 2019 across Spanish municipalities. Additionally, data on municipal-level corruption is incorporated to explore the drivers of this effect. The main findings show that municipalities that gained internet access significantly punished the PP, and this effect was notably stronger in municipalities with perceived corruption cases in previous years. These results underscore the importance of Internet access in shaping voter decisions and the electoral penalty for corruption scandals.
