The presidential election of 2012 produced a high turn-out. Only 20 percent of the electorate abstained. This significant mobilization, however, hides renewed social inequalities in political participation that seemed to have previously disappeared. Based on national and local data surveys, this paper shows that certain kinds of people are less likely to vote than the average citizen. While traditionally more prone to abstain than other voters, many young, poorly educated, and suburban people participated in the presidential election in 2007, but not in 2012. In this later case, they seem to have not been interested in the electoral campaign.
