Third poll gives Zuluaga edge over Santos in Colombia presidential race

CARTAGENA (Reuters) - Colombia's right-wing presidential candidate Oscar Ivan Zuluaga is edging ahead of President Juan Manuel Santos in three voter polls after a survey published on Friday also showed Santos's recently comfortable lead has evaporated nine days before elections.

But the poll was conducted before Friday's announcement that the government had reached a deal with Marxist FARC guerrillas on ending the illegal drug trade. That key advance in peace talks that Santos started with the rebels in 2012 could prop up his support from those eager to see a peace deal.
