This paper examines the predictors of online participation and compares them to classic theories which emphasize sociodemographic and cultural resources. It also considers the impact of digital skills and some political attitudes like confidence in political parties. The study is based on two online surveys conducted among citizens who used Internet for electoral purposes during the 2012 French presidential and Quebec legislative elections. Age, confidence in political parties, and digital skills are significant predictors of online participation. In contrast, online participation is not positively related to education level and job category.
