Video - Is democracy the answer to Nigeria's woes?

Millions of Nigerians finally get to vote for a new leader on Saturday after the election was postponed by a week. Whoever wins will have to address at least three pressing issues, the sluggish economy, security problems and corruption. It's expected to be a tight race between President Muhammadu Buhari, who is seeking a second term, and Atiku Abubakar the main opposition candidate. Buhari has promised to fight corruption but his opponents have focused on what they say has been his failure to fix the economy. The main contenders made their final appeal for votes on the last day of campaigning on Thursday. So, will elections make any difference?
