Armenia's incumbent President Serzh Sarkisian was set for a triumphant re-election Monday against a weakened opposition in polls seen as a crucial democratic test for the ex-Soviet state. Sarkisian, president since 2008, was set to win another five-year term with 58 percent of the vote, an exit poll by Gallup said after close of polls. His nearest rival, former foreign minister Raffi Hovannisian, was set to come second with 32 percent. Former prime minister Hrant Bagratian was on course for three percent as was the Soviet-era dissident Paruyr Hayrikyan, the exit poll said.
