NIGERIA-VOTE-JONATHAN

Nigerian President and Presidential candidate of the ruling People's Democratic Party Goodluck Jonathan (R) waves to supporters as Vice President Namadi Sambo (L) looks on during a rally in Lagos on January 8, 2015. Nigeria's President Goodluck Jonathan on Thursday formally began his campaign for re-election, taking the fight to a key opposition stronghold with a mass rally. The meeting in Lagos comes as Jonathan's Peoples Democratic Party (PDP) mounts increasingly personal attacks on his main challenger as well as lingering doubts about whether the vote will even hold.
