We take advantage of a quasi-natural experiment in Évora, Portugal, to evaluate the impact of electronic voting on the 2019 European election results. We rely on difference-in-differences estimations, with control groups chosen by matching methods, and findthat the turnout rate decreases by 2 percentage points, a decline mostly explained by the decrease of the Communist Party’s vote share. Socio-economic characteristics of these voters, including higher age, and lower education and income levels, may explain the results. We performed an on-site and online questionnaire, and find that those participating, mostly highly educated, were for the most part aware of and shared a positive view of the electronic voting procedure, described as ‘easy’ and ‘effective’
