Of the over 60 political parties in Nigeria, the most keenly and fiercely contested presidential primary is that of the PDP because an incumbent President is running, and a former vice president has vowed to defeat him.

The two candidates have been engaged in serious blackmail of each other in newspaper, radio and TV advertisements. Abubakar is accusing the President of not completely declaring his assets completely.

Jonathan, in turn, is accusing Abubakar of money laundering, and says Abubakar will use force to effect change, should he lose.

Eagle Square, in Abuja, has been cordoned off, as it is where the party will chose its candidate, and was the spot where bombers wanted to attack in October. Motorists are being diverted to different routes to avoid passing through the venue.
