Nigerians will head to the polls Saturday in a fiercely-contested presidential vote that analysts say is too close to call. It will be the largest democratic exercise on the continent as Africa's most populous nation picks a new president. The crucial election comes as the country battles myriad economic and security problems that range from fuel and cash shortages to rising terror attacks, high inflation, and a plummeting local currency.

尼日利亚星期六将举行总统选举，竞争激烈。分析人士说，此次选举双方势均力敌，将难分胜负。在这个非洲人口最多的国家选出新总统之际，这将是非洲大陆规模最大的民主选举。这次至关重要的选举正值尼日利亚面临各种经济和安全问题之际，这些问题包括燃料和现金短缺、恐怖袭击增多、通货膨胀率高以及本币贬值。

For the first time since the country's return to democratic rule in 1999, none of the candidates is an incumbent or a former military leader. Outgoing President Muhammadu Buhari is term-limited and will step down amid a patchy legacy that has brought "a lot of frustration and anger" to Nigerian voters, analysts say.

自从尼日利亚1999年恢复民主统治以来，这是第一次总统候选人不是现任总统或前军事领导人。分析人士表示，即将离任的总统穆罕默杜·布哈里任期有限，他将在一个不完整的遗产中下台，这给尼日利亚选民带来了“许多沮丧和愤怒”。
