John Mahama's first tenure as President of Ghana began when he succeeded John Atta Mills following the latter's death in office on 24 July 2012. Mahama previously served as Vice-President of Ghana from January 2009 to July 2012, and is the first head of state of Ghana to have been born after the country's independence. He was elected after the December 2012 election for a full term as president.

Upon assuming office, Mahama continued the Better Ghana Agenda policy vision initiated by his predecessor. He contested re-election for a second term in the 2016 election, but lost to the New Patriotic Party candidate Nana Akufo-Addo. This made him the first president in the history of Ghana to not have won a second term consecutively. He left office on 7 January 2017, and was re-elected as president in 2024.

2012 general election

Incumbent president John Mahama was declared winner of the presidential election with just 50.7% of the vote, a few thousand votes over the threshold for avoiding a run-off election. Nana Akufo-Addo on the other hand received 47.74%. However, the opposition did not accept the results and accused the Electoral Commission (EC) of tampering with the results. The opposition filed a petition at the Ghanaian Supreme Court to review the election results but Mahama was declared as president, winning a full term.

Reactions

The non-partisan Coalition of Domestic Election Observers (CODEO), the Economic Community of West African States (ECOWAS) and the African Union (AU) all declared that the elections were, for the most part, free and fair. Despite this, there were still widespread allegations of voting irregularities, though these were dismissed as unsubstantiated by the electoral commission chairman. As a result of these claims, the New Patriotic Party immediately rejected the results upon their release and its candidate, Nana Akufo-Addo, remarked that his party's leaders would be meeting on 11 December to consider their options, one of which is to contest the results by lodging an appeal in court. Violent opposition was however ruled out.

African Union commission chairman Thomas Boni Yayi flew to Ghana to meet with the two men. He was also reported to have congratulated Mahama on his victory, and charged him to preside over an all-inclusive government. Yayi praised the conduct and the participants of the election.

In anticipation of petitions regarding the election, Chief Justice Georgina Theodora Wood has established two public complaints secretariats to swiftly process such concerns. In a statement after being declared the victor, Mahama gave a reconciliatory message, saying "I wish to welcome my fellow candidates to join me now as partners in the project of nation building and of creating a better Ghana".

Inauguration Mahama was inaugurated on 7 January 2013. Thirteen African Heads of State, one Prime Minister, two Vice-Presidents and 18 government delegations across the world attended his inaugural ceremony at the Black Star Square in Accra when Mahama was sworn-in to begin his own four-year term. He said in parliament upon being sworn in: This is the saddest day in our nation's history. Tears have engulfed our nation and we are deeply saddened and distraught and I'm personally devastated, I've lost a father, I've lost a friend, I've lost a mentor and a senior comrade. Ghana is united in grief at this time for our departed president.

Policy

National affairs Dumsor

Dumsor is the frequent, persistent and irregular system of electrical power outage in Ghana. The frequent Ghanaian blackouts are caused by power supply shortage. Ghanaian generating capacity by 2015 was 400-600 megawatts less than what Ghana needed. Ghanaian electricity distributors regularly shed load with rolling blackouts. At the beginning of 2015, the dumsor schedule went from 24 hours with light and 12 without to 12 hours with light and 24 without. In August 2012, the government told Ghanaians that a ship's anchor cut the West African Gas Pipeline (WAGP), forcing gas turbines to shut down for lack of fuel. The Mahama government blamed it on the government's inability to add significant generating capacity over the years and promised to fix this. Karpower Burge was brought in to solve the problem. The government stated that it has plans to diversify its energy sources, using more renewables. It was also working to encourage energy conservation.
