Akufo-Addo, 76, has been touting economic growth during his current four-year term in office as well as the streamlining of government services and implementation of free schooling for senior high school pupils.
Mahama, 62, has meanwhile stressed the many infrastructure projects, including roads, bridges, schools and hospitals, he realised during his presidency, promising do invest more in this area if re-elected.
Political analysts of the University of Ghana in the capital, Accra, predict a slim win for Akufo-Addo in the December elections.
Polls have indicated voters prefer Akufo-Addo’s policy-driven approach to running the nation of 30 million people, the university’s head of the political science department, Kaakyire Frempong, told dpa.
A candidate needs to gain at least 50 per cent of votes to be elected in the first round.
Ghana’s roughly 17 million registered voters will also elect 275 legislators from 914 candidates on Dec. 7.
Akufo-Addo’s NPP is expected to once again gain the majority of seats in parliament.
