International Business Times quotes Africa Center Director J. Peter Pham on Muhammadu Buhari’s win in Nigeria’s 2015 election:
Buhari also managed to win votes that went to the Action Congress of Nigeria in the previous election in 2011, according to J. Peter Pham, director of the Africa Center at the Atlantic Council. ACN was one of four opposition parties that merged in 2013 to form the APC, aimed at ousting the PDP, which had won every presidential election since 1999.
