Colombia Presidential Election 10 Days Away: Cepeda at 37% vs. De la Espriella at 29% — Runoff June 21 Increasingly Likely; Peace Architecture Verdict at Stake

Ten days before Colombia's presidential election on May 31, 2026, the latest AtlasIntel polling confirms that no candidate is on course to win a first-round majority, making a June 21 runoff highly probable. The most recent survey shows left-wing Senator Iván Cepeda (Pacto Histórico) at approximately 37.4%, right-wing Abelardo De la Espriella at 29.4%, and center-right Paloma Valencia (Democratic Center) at 20.9%. Cepeda's lead has narrowed from 44.3% in the April 26 Invamer poll, reflecting voter consolidation around De la Espriella as the anti-Petro option. A Cepeda-De la Espriella runoff on June 21 would represent the starkest peace-process binary Colombian voters have faced since the 2016 plebiscite: Cepeda would resume ELN negotiations and possibly re-engage FARC-EMC dissidents; De la Espriella has committed to ending all peace negotiations and pursuing military operations. Valencia would pursue a military-first approach while sustaining JEP processes. The election's peace-process implications extend across multiple active mechanisms: the JEP (Special Jurisdiction for Peace) is advancing macro-case 01 on 6,402+ military extrajudicial killings toward judgment, a process that continues regardless of electoral outcome; the 2016 FARC accord's rural reform and crop substitution programs, which have less than 40% implementation after a decade, face termination under a De la Espriella government; the ELN's unilateral pre-election ceasefire (declared February 2026) is holding in most areas but its post-election future depends entirely on the election result. The Wikipedia summary of the 2026 Colombian presidential election captures the moment: the outcome 'may determine whether Colombia's peace process survives its most significant political transition since 2016.' International observers (OSCE, OAS, EU) are deploying election monitoring missions. Colombia has 1,122 municipalities, of which 185 face documented electoral violence risks.
