— Pacto Histórico presidential candidate Iván Cepeda formally challenged Paloma Valencia and Abelardo de la Espriella to a debate on April 18, reversing his February refusal to participate in any televised confrontation.
— Both rivals accepted within hours, each demanding their own conditions — Valencia asked for this week, a neutral moderator, open-broadcast TV and no scripts; De la Espriella invited major national outlets to organize the format.
— The challenge arrived with 41 days left to the May 31 first round, a judicial tutela pending to force Cepeda to debate, and Cepeda polling at 35% against Valencia’s 16% and De la Espriella’s 21-22% in recent surveys.
The Colombia presidential debate breakthrough came at a Sumapaz rally on Saturday, April 18, when Iván Cepeda — the Pacto Histórico’s standard-bearer and President Gustavo Petro’s chosen successor — called on the two leading right-wing candidates to face him in a televised confrontation. “I challenge the extreme right, its two candidacies, to debate on substantive proposals, visions of country, and models of development and social equity,” Cepeda said.
The Rio Times, the Latin American financial news outlet, reports that the challenge is a direct reversal of Cepeda’s February 20 position, when he publicly announced he would not attend any presidential debates. A judicial tutela filed this month by former senator Jonatan Tamayo Pérez sought to order him to appear in at least two televised debates before the May 31 first round. That legal pressure, combined with the arrival of rivals’ debate-attendance pledges, appears to have forced the reversal.
Paloma Valencia of the Centro Democrático responded first, accepting the challenge with demands: a debate “this same week,” a neutral moderator, open-broadcast television, and no prepared scripts or cue cards. She proposed four discussion pillars: the results of Petro’s “Total Peace” initiative, the security crisis, the healthcare and pensions situation, and the decision to import gas and oil while halting exploration.
How the Colombia Presidential Debate Got Unstuck
Abelardo de la Espriella, the independent nationalist lawyer polling in second place, accepted the challenge the same Saturday. He called Cepeda “the candidate of Petro and the FARC” and claimed only the tutela had forced Cepeda into the confrontation. De la Espriella named five prospective media organizers: Caracol TV, Noticias RCN, El Tiempo, Blu Radio and W Radio.
By Monday, April 20, both Valencia and De la Espriella had added procedural conditions, opening a second negotiating round over format and moderators. Centrist figures — former senator Roy Barreras, ex-Bogotá mayor Claudia López, and perennial moderate Sergio Fajardo — publicly asked to be included in the debate, warning that a three-person confrontation would exclude voices that matter to the center electorate.
The stakes sit inside the math. As the Rio Times analysis of the March 20 GAD3 poll documented, Cepeda holds 35% in the first round against De la Espriella on 21% and Valencia on 16%, and in head-to-head runoff simulations Cepeda beats De la Espriella 45-36 but narrowly leads Valencia 43-40. That narrow margin is the reason the right has been demanding debate access for months.
The Valencia-Oviedo Ticket and the Centre Squeeze
Valencia’s runoff strength depends heavily on her March 12 selection of Juan Daniel Oviedo as her running mate. Oviedo, a former director of Colombia’s statistics agency DANE under the Duque administration and runner-up in the March 8 Gran Consulta por Colombia with more than 1.2 million votes, broadens the Centro Democrático ticket toward the moderate center.
The two presented their “Colombia Más Grande 2026” government plan in Bogotá on April 13. Oviedo — an openly gay economist with a reputation for data-driven policy — creates ideological tension inside the party, but his presence on the ticket answers Valencia’s structural weakness: capturing voters who reject both Petrismo and the hardline right.
Cepeda’s running mate is Aida Quilcé, an indigenous-rights leader announced March 9. That ticket consolidates the left-coalition identity but does less to broaden the first-round coalition. The Valencia-Oviedo pairing is therefore engineered for exactly the second-round squeeze the GAD3 poll anticipates.
Petro’s Fraud Allegations and the Judicial Pushback
The debate reversal arrives against a backdrop of escalating presidential-level intervention. President Petro has repeatedly alleged fraud in the 2014, 2022 and 2026 legislative elections, prompting the Tribunal Administrativo de Cundinamarca to order him on April 10 to correct his X posts within three days and to moderate his rhetoric about the Registraduría. His lawyer Alejandro Carranza has appealed the ruling on free-expression grounds.
Valencia has made the Petro-Cepeda linkage central to her campaign. On Sunday she tied Petro to past scandals including alleged meetings with contraband czar Diego Marín Buitrago — known as “Papá Pitufo” — and to the sanctions imposed on his 2022 campaign for violating spending caps. “He who does it imagines it,” she wrote, turning Petro’s fraud allegations back on the presidential campaign itself.
Petro has publicly said a Cepeda defeat would be a personal setback, a statement that doubles as a threat to contest results and as an admission that Cepeda’s campaign is weaker than Pacto Histórico’s congressional showing suggested. The Rio Times January assessment of the race flagged Petro’s constituent-assembly push as the rails under which his successor would contest the election; the legal fights are those rails being tested.
Security and the Violent Backdrop
The campaign is unfolding inside a security environment that has deteriorated sharply. Both Valencia and De la Espriella have received direct threats from armed factions, with the ELN declaring De la Espriella a military target on February 10. The Misión de Observación Electoral now classifies 170 municipalities as electorally at-risk — a 30% increase over 2022 — with 81 rated extreme.
As Rio Times reporting on the electoral-violence landscape documented, congressional candidates in departments like Arauca, Cauca and Norte de Santander require permission from armed groups to campaign. The televised debate format is itself a security event — one of the few settings where all three leading candidates will appear in the same physical space.
Regional context is also pressuring Bogotá — Petro’s threat to withdraw Colombia from the Comunidad Andina remains unresolved, and the Colombia-Ecuador trade war triggered by Noboa’s 100% tariff retaliation is ongoing. The COLCAP closed Monday down 0.65% at 2,286.82 points as investors weighed the accumulating political and regional risk.
What Happens Next
Three items now shape the next ten days. The first is whether the debate actually takes place this week as Valencia demanded, or slips to May as the tutela-compliance minimum. Each day of delay reinforces the perception that Cepeda is avoiding the confrontation he was forced to accept.
The second is whether the center candidates — Fajardo and López, both polling around 3-4% — secure formal inclusion. A three-person debate preserves the GAD3 poll dynamic. A five-person debate fragments the right and could push De la Espriella voters to reconsider Valencia, further narrowing the Cepeda-Valencia runoff gap.
The third is Petro’s disposition. As documented in the Rio Times profile of De la Espriella’s outsider campaign, presidential rhetoric about fraud now carries direct post-election stakes. If Petro escalates his X campaign despite the court order, the debate will double as a setup for contested results — and Latin America’s third-largest economy will head into June with an unresolved legitimacy question.
