"Allegations about kampanjsabotage, threatening the life and arrest of supreme court chairman to shade the run-up to this weekend's elections in Nigeria. And there are concerns about electoral fraud and violence."
"It means enough to the kind of ethnic tensions which in this context tend to come up to the surface can end up in the dark," says Peter Stein, economist and Afrikaexpert, TT."
"Both candidates have extensive political experience and go to the elections with similar promises – that the development of the economy, the fight against corruption and to stem the deadly violence raging in many parts of the country."
"But despite the fact that they are, at least on the surface, do not differ so much the fear of many that the choice can be scared."
"– the Question many people are asking themselves now is if the election goes right. It will probably be even, it will be controversial and it will probably be turbulent the last time during the election campaign, " says Stein."

"– Buhari has managed to combat some of the terrorrörelsen Boko Haram and curb violence in northern Nigeria. And on a personal level, he has an understated appearance and is not particularly corrupt as far as we know. A part in the fight against corruption, he has succeeded, but it has been done with the very authoritarian methods. So he also has a whimsical style as president, it is a little bit erratic, " says Stein."
"But the economy is one of the main issues in the election, and where there is a large discontent among the population over Buharis rule. He has not honoured their promises. Buharis economic mistake is, inter alia, that he overstated the exchange rate and not managed to develop a more varied economy, while oil prices dropped – which has led to corruption in practice has increased."
