When no candidate wins 50% in the first round, there is a runoff between the top two candidates.
Counting for yesterday's election is still in progress, but Nana Akufo-Addo (NPP) is reportedly in the lead with 49.5% of the vote, so a second round may be required. In 2009, the NPP candidate won in the first round but the incumbent NDC candidate won in the second round.
John Dramani Mahama (NDC) 50.7%
John Agyekum Kufuor (NPP) 52.5%
John Atta-Mills (NDC) 44.6%
Jerry John Rawlings (NDC) 57.4%
John Kufuor (NPP) 39.7%
Jerry John Rawlings (NDC) 58.40%
Albert Adu Boahen (NPP) 30.29%
