Under normal circumstances,when citizens of a country involve in a mass protest,the president if been unable to meet up to their demands steps down just at it happened in Egypt,SouthKorea,Lesotho etc.But I think buhari ought to follow the same pattern.
If he is unable to Care for the need of the country as we've seen at the protests and provide the demands of Nigerian protesters,buhari should resign.He has failed woefully in all aspects of governance.I think that's the best thing for him to do.
Only zombies and paid miscreants would still support buhari as still been good enough to rule Nigeria
