Factbox: Candidates in Colombia’s presidential election


(Reuters) – Colombian President Juan Manuel Santos is running for a second term in a May 25 election. Polls show he could lose to right-wing candidate Oscar Ivan Zuluaga in a June run-off. The main campaign issue has been peace talks with Marxist guerrillas that Santos launched in 2012 in hopes of ending a 50-year war. Critics say he may be offering the rebels too much but Santos says a peace deal is vital to Colombia’s future.
