Octogenarian President Abdoulaye Wade, whose bid for a third term has brought violent protests to Senegal, faces a tough challenge from former ally and prime minister Macky Sall in the second round of voting on Sunday.
Wade fell short of a majority in the February 26 vote with 34.8 percent. Sall came second with 26.6 percent. The first-round candidates have now united behind Sall as has civil society group M-23, which has been calling on Wade, 85, to step down.
