The Economist explains why young people don’t vote:
Yet perhaps the most depressing explanation is simply that in many places, young people do not feel that there is anyone worth voting for. A long-running European survey found that in 2008, 22% of French 15- to 24-year-olds said they believed society’s problems could be fixed only by revolutionary action. In 1990 the equivalent figure was just 7%. When charismatic politicians do appear, they can win over the young: Barack Obama would not have been elected in 2008 and 2012 had it not been for remarkably high youth turnout in his favour. But for the most part, such politicians are few and far between. That might be because in most elections, a simpler strategy is to win over older people, who will vote however bad the candidates are. Young people—who tend to be more cosmopolitan, liberal and hopeful than their elders—tend to be switched off by the negativity and cynicism of election campaigns targeting the unhappy old. Sadly, cynicism then breeds cynicism.
