This paper examines the effect of the introduction of broadband Internet on voting and campaign donations in the 2000s. To identify the effect of broadband, I use an instrumental variable strategy based on geographic terrain attributes which affected the cost of building cable infrastructure. I find that broadband has led to a large increase in voter turnout in presidential elections, as well as an increase in the total amount donated to political campaigns. Consistent with the hypothesis that Democrats have a stronger online presence, I also find a large effect on Democratic vote share in presidential elections. Evidence suggests the existence of both direct and indirect channels for the broadband effect. In particular, I find that broadband availability is associated with greater political knowledge, an increase in online (but not offline) donations, and the promotion of liberal values.
