"Nigerians should be prepared to deal with any new betrayal by any ruler with the same passion and commitment.... as they did with Sani Abacha because we cannot continue this cycle of repetitious evil and irresponsibility."
The vote was controversially postponed due to security concerns, even though many suspect political reasons for the delay.
Election officials said the military would be too busy fighting Boko Haram in the north-east to be able to help with security across the nation.

(http://news.bbcimg.co.uk/media/images/75306000/jpg/_75306515_line976.jpg) As part of the effort to counter the jihadist threat, Mr Soyinka called for "an aerial bombardment with weapons of the mind" in addition to the military offensive.
"All kinds of propaganda leaflets should have been raining in those areas because not all members of Boko Haram are convinced. They need to know there is an exit and the state will take care of them. Then the waverers' minds have to be reinforced on the positive side - on the side of humanity," Mr Soyinka said.
"The kind of propaganda being used now between the political parties, just a fraction of that should have gone into attacking Boko Haram," he added.

'Notoriously expensive' Africa's first Nobel laureate hopes the country will stay intact but does he think the map of Nigeria will be the same in 10 years time?
"I doubt it very much. The threats of dismemberment have been going on so long that one of these days there is going to be a wish fulfilled.
"The idea of either dismembering at the cost of human lives, as the Boko Haram people are trying to do with their caliphate delusions or to force people to stay together as happened in the case of the [1967-1970] Biafra war, it doesn't make sense, it's an abuse of intelligence.
"Arrangements can be made in which people stick together under protocols of association which allow some kind of autonomy for certain issues and other cases centralised policies," he said.

The problem is likely to be exacerbated by the fact that Nigeria's elections are notoriously expensive. The BBC was told of a senator needing a campaign war chest of at least 200m naira ($980,000; £640,000).
Mr Soyinka says the staggering amounts will inevitably lead to broken electoral promises.
"What does this make of the incoming government? This money came in from somewhere. It means such candidates are going to owe, they are obliged to interests which are not necessarily in the best interests of the nation," Mr Soyinka said.
"So a lot of the electorate will be disappointed at the failure - the reneging on electoral promises - because there may not be funds for the fulfilment of those promises," he said.
