A 2016 peace accord led to the demobilization of thousands of fighters from the FARC rebel group last year, but while some Colombians want to forgive and move on, others are frustrated, insisting on harsher punishment for FARC leaders than is currently pending. On the other, leftist candidate Gustavo Petro, a former M-19 guerrilla and mayor of Bogotá, has voiced a desire to push the accord forward, but may lack the political support to do so if elected. Leading the polls is conservative former senator Ivan Duque, the protege of former President Alvaro Uribe, the chief critic of the peace deal, but surveys suggest he is unlikely to get the more than 50 percent of votes required to avoid a June runoff. The accord was slightly amended and it later passed in congress by a vote of 130-0 in the Lower House and 75-0 in the Senate (members of Uribe’s party abstained from the vote.) Here's a glance at who's running and what's at stake:

Polls indicate that the two leading candidates are Gustavo Petro, a leftist running on an anti-establishment platform, and Ivan Duque, a conservative lawyer and former senator who has promised to change some provisions of the 2016 peace deal with the Revolutionary Armed Forces of Colombia. Petro was a member of the disbanded M-19 guerrilla movement in his youth and later was elected to the Senate, where he led corruption investigations into the links between right-wing paramilitary groups and regional political dynasties.
