Senegalese vote on Sunday in an election President Macky Sall is expected to win after strong economic growth in his first term, while rights groups criticise him for squeezing out rivals.
Senegalโs small fish-exporting economy expanded more than 6 percent last year, one of the highest rates in Africa, driven by construction of a new railway and other projects.
The 57-year-old told thousands gathered for his final rally in Dakar on Friday that he would deliver universal healthcare and better access to education in a second term.
โVictory in the first round is inevitable,โ Sall told a crowd earlier in the week.
About 6.5 million people are registered to vote at polling stations that are due to open at 8 a.m. (0800 GMT) and close at 6 p.m. Official results are due out on Friday with a run-off for the top two on March 24 if no one secures a majority.
Opinion polls are banned in the run-up to the vote, but a survey by a Senegalese data company in November gave Sall 45 percent support. Of his four rivals now lined up in the smallest field of candidates since 1988, none had more than 16 percent.
Despite Sallโs popularity, some citizens question whether a high-speed train, new motorways and a swanky conference centre will benefit average citizens in the former French colony of 15 million people where average income is less than $200 a month.
Many people do not have reliable water or power supplies.
Rights groups have criticised the exclusion of two popular candidates from the race in the West African nation that has long been viewed as the regionโs most stable democracy. It has seen peaceful transitions of power since independence in 1960.
Former mayor of Dakar Khalifa Sall and Karim Wade, son of former President Abdoulaye Wade who was in power from 2000 to 2012, were barred from running due to corruption convictions.
The former president said in a statement the vote was being rigged and told supporters of his son to boycott the poll.
The government has dismissed the criticism, promising a free and fair vote.
The remaining challengers are third-time contender and former Prime Minister Idrissa Seck, and Ousmane Sonko, a former tax inspector who is popular among the youth. Lawyer Madicke Niang and IT professor Issa Sall are also running.
Sonko told supporters at his final rally on Thursday that he would congratulate Sall if the vote was fair. โBut if he steals the victory, I ask the youth to walk to the presidential palace and chase him out,โ he said.
At least one person was killed this month in clashes between Sallโs backers and his opponents in the southeastern city of Tambacounda, but campaigning has been largely peaceful.
