Two men in their 70s are candidates in the Nigerian presidential election on Saturday. Yet half of the country’s registered voters are young people between 18 and 35 years of age. The two men are well-known to voters. It is the fifth election campaign for President Aisha Muhammadu Buhari, who was a military ruler in the 1980s. Buhari, now 76 years old, is seeking re-election as president. This is the fourth campaign for Atiku Abubakar, the main opposition candidate. Abubakar, now 72, was vice president from 1999 to 2007. The presidential election offers little hope of change for young people in a country where nearly 25 percent of the workforce is unemployed. Some fear anger over the lack of jobs may lead to violence.
