Nigeria is holding elections Saturday following two years of political unrest. Voters will elect both a president and parliament.
The ruling People’s Democratic Party, or PDP, is facing its first real test since coming to power in 1999. The lead opposition party, the All Progressives Congress, has become a powerful player in Nigerian politics since it formed in 2013.
How did it happen?
The All Progressive’s Congress, or APC, developed from an alliance of at least three regional Nigerian parties in 2013. The resulting group was large, but critics still said the new party would not survive.
But then leading PDP members began to withdraw from that party, and joined the APC.
