Voters in Africa's most populous nation are deciding Saturday whether to keep their accidental president in power, though unease among Nigeria's Muslims about the Christian leader could force a runoff in this oil-rich country where elections have long been marred by fraud and violence.
Security remains a concern after bombings struck the country's northeast during last week's legislative elections, and police manning checkpoints will confine people to their neighborhoods through Saturday night.
"This election is very important," said Hamza Mohammed, 50, who serves as a local market chairman in Katsina. "We want it to be conducted peacefully and we want peace to reign."
Voters must choose whether President Goodluck Jonathan should now be elected after taking over last year when his predecessor died in office following a lengthy illness.
Jonathan is the candidate for Nigeria's long-dominant ruling party and is the clear front-runner, but several other candidates threaten to siphon off enough votes that it could go to a second round for the first time since Nigeria became a democracy 12 years ago.
"I don't think the same people can bring change in the next four years," Ita Emmanuel, 32, a social worker, said as he waited to cast his ballot in the megacity of Lagos, where the streets normally clogged with traffic, vendors and pedestrians were desolate early Saturday.
In order to win, Jonathan must receive a minimum level of support from across this enormous West African country of 150 million, a complicated formula somewhat similar to the American electoral college system. He cannot win the presidency outright unless he carries at least a quarter of the votes cast in at least two-thirds of states and the capital.
Nigeria, though, largely splits though between a Muslim north that nears the Sahara Desert, and a Christian south of forests and swampland.
While Jonathan is embraced in the nation's predominantly Christian south, many in the country's Muslim north believe one of their own should have had another turn after the Muslim president died in office in May 2010.
Among those looking to take away key votes from Jonathan in northern Muslim constituencies is a hometown candidate; former military ruler Muhammadu Buhari.
He ruled Nigeria shortly after a 1983 New Year's Eve coup, executing drug dealers and going after corrupt officials while also stifling freedom of speech and jailing journalists. Former anti-corruption czar Nuhu Ribadu is also running.
Many hope Saturday's vote will help Nigeria atone for years of marred polls since it became a democracy only 12 years ago. International observers roundly rejected Nigeria's 2007 poll as being rigged and marred by thuggery, though it represented the nation's first civilian-to-civilian transfer of power.
Both Jonathan and the leader of the country's Independent National Electoral Commission have promised a free and fair vote Saturday. However, election workers have clamored for life insurance and police protection.
During legislative elections last weekend, violence erupted in northeastern Nigeria, where a radical Islamic sect operates, leaving a hotel ablaze, a politician dead and a polling station and a vote-counting center bombed.
On Friday night, Nigerian television networks began showing a video captured on YouTube of what appeared to be a woman at a polling place in last week's election pressing her thumb to a number of fraudulent votes.
The individuals who posted the video did not respond to a request for comment from The Associated Press, which could not immediately verify the authenticity of the footage.
