Polls opened in a general election in Ghana Saturday, poised to be a litmus test for democracy in a region shaken by extremist violence and coups.

Some 18.7 million people are registered to vote in presidential and legislative elections but the two main candidates offer little hope for change for the nation.

Ghana used to be a poster child for democracy in the region, but in recent years, it has struggled with a profound economic crisis, including surging inflation and a lack of jobs.

At a time when democracy in western Africa is threatened by coups, Ghana has emerged as a beacon of democratic stability with a history of peaceful elections. It had also been an economic powerhouse, priding itself on its economic development.

But recently that has been changing: 82% of Ghanaians feel their country is headed in the wrong direction, according to an opinion poll released by Afrobarometer, a research group, earlier this year.

Although 12 candidates are running to become Ghana's next president, Saturday's election — like previous ones since the return of multiparty politics in 1992 — has emerged as a two-horse race.

Vice President Mahamudu Bawumia is the candidate of the New Patriotic Party, or NPP, the ruling party that has struggled to resolve the economic crisis. He faces off against former President John Dramani Mahama, the leader of the main opposition party National Democratic Congress, or NDC. He was voted out in 2016 after failing to deliver on promises for the economy.

The NDC prides itself as a social democratic party, while the ruling NPP tags itself as leaning to the right. But in fact, analysts and voters said, the programs of their presidential candidates do not differ in a significant way.

Two hundred seventy-six members of parliament will also be elected Saturday. The ruling NPP party and the main opposition NDC each have 137 members in the 275-member legislature, with one independent member who has been voting mostly along with the ruling party. One more constituency will be allowed to vote in this election, bringing the number of deputies to 276.

In their final campaign rallies Thursday, both candidates made a last push to pitch their political parties as the answer to Ghana's economic woes.

Bawumia, 61, an Oxford-educated economist and former deputy governor of the country's central bank, promised to build on the outgoing administration's efforts and stabilize the economy.

Mahama, 65, on the other hand, restated his promise to “reset” the country on various fronts. “We need to reset our democracy, governance, economy, finances, agriculture, infrastructure, environment, health sector, and all that we hold dear as a people,” the former president said.
