of Nigerian politics, where personalities count as much as ethnic and religious identity, the campaign has predictably descended into a smear campaign.
On Wednesday, Jonathan’s campaign chief Femi Fani-Kayode described former military ruler Buhari as a “great danger” for the unity of the country.
The 72-year-old from the Muslim-majority north, who is standing for the presidency for the fourth time since 1999, “represents a return to an ugly past which is best forgotten”, he said.
He also questioned Buhari’s democratic credentials and described his record in public office as “shameful and disastrous”.
Buhari ousted civilian president Shehu Shagari in a military coup in 1983 and his 18-month rule was characterised by a hardline stance on corruption.
“We do not believe that Nigeria ought to be run by a man that is not capable of tolerating dissent or by a political party like the APC that has no sense of remorse, restraint or decency,” he added.
The APC, a coalition of opposition parties, is seen as having its best chance of winning power since Nigeria returned to civilian rule 16 years ago and said the PDP was running scared.
“The real danger to democracy in Nigeria is Jonathan,” party spokesman Lai Mohammed told AFP. “Before he came into office in 2010, Nigeria was a united country. But it is no more now...
“Buhari is also a good party man. The orgy of violence, armed robbery, killings, kidnappings and other forms of crime under Jonathan’s watch is unprecedented in the history of Nigeria.
“We have more than 20,000 square kilometres of our land now occupied by Boko Haram.”
The opposition has previously denounced a secret police raid on its Lagos offices and the teargassing of opposition lawmakers outside parliament last year as politically motivated.
Nigerian elections have been characterised by political violence and there have been warnings that this year’s vote could be no different.
This week, the APC claimed that Buhari supporters were shot as they made their way to a rally in the southern oil city of Port Harcourt on Tuesday.
