On the eve of Nigeria’s election on Saturday, the spectacle of campaign expenditure is at odds with the rampant poverty afflicting many.

The lack of campaigning in impoverished areas contrasts with the election-time bustle of downtown Abuja, where the capital’s streets are adorned with colorful posters of presidential candidates and where their followers are bused to boisterous events.

It also highlights the frustration many of Nigeria’s poor feel amid an election campaign said to be one of the country’s most expensive ever as incumbent President Muhammadu Buhari tries to shake off the challenge of his billionaire rival, Atiku Abubakar.

Unemployment in Africa’s most populous nation of 190 million was over 23 percent in the third quarter of 2018, up from 8.2 percent when Buhari took office, official figures show.
