Colombia's 2026 presidential race takes shape as candidates announce running mates

Colombia's presidential race crystallized this week as the leading candidates announced their vice-presidential running mates, each choice a calculated signal about how they intend to govern and whom they hope to win over. The shape of the campaign—fractured along ideological lines, shadowed by fraud allegations, and driven by the arithmetic of coalition-building—became visible in these pairings.

Sergio Fajardo, the centrist former mayor of Medellín, chose Edna Bonilla, an academic and former education secretary of Bogotá under Claudia López. He announced the decision at dawn on the campus of the National University, where both had taught. Fajardo framed Bonilla as a bridge-builder in a polarized moment. "She knows how to construct bridges, not trenches," he said, emphasizing that she was not a household name but represented a different kind of politics—one rooted in dialogue rather than confrontation. Bonilla, speaking at the same event, pledged to center education, security, health, and women's issues in the campaign. The choice signaled Fajardo's bet that voters hungry for consensus would reward a ticket of two academics with track records in public service.

On the left, Iván Cepeda of the ruling Pacto Histórico coalition paired himself with Aida Quilcué, an indigenous senator and longtime activist. The announcement came after a bureaucratic tangle—missing documents delayed the formal registration by nearly six hours—and amid questions about whether Quilcué faced legal obstacles to the candidacy. The coalition's leadership moved quickly to defend her, clarifying that she had properly transitioned between parties and faced no disqualification. Cepeda's choice of an indigenous woman, a victim of Colombia's long conflict, underscored the government coalition's claim to represent historically marginalized constituencies. Luis Gilberto Murillo, another centrist-leaning candidate with roots in the Pacific coast region, selected Luz María Zapata, a political scientist who had led the association of Colombian mayors. Both moves suggested that the center and center-left were attempting to position themselves as alternatives to the polarized extremes.

The right-wing race proved more turbulent. Paloma Valencia, who won the conservative primary consultation with over three million votes, spent days in negotiations with Juan Daniel Oviedo, who finished second with 1.2 million. Oviedo had positioned himself as more open to respecting the 2016 peace accord with the FARC—a position anathema to Valencia's uribista base. The two met repeatedly, but Valencia eventually concluded that Oviedo was uncomfortable with the arrangement. "He doesn't have an obligation to be my running mate, and I don't have an obligation for him to be," she said, signaling that she would look elsewhere. The delay frustrated observers and revealed the fault lines within the right: between those like Valencia, ideologically hardline but tactically flexible, and those like Oviedo, who wanted to signal openness to the center. Former president Álvaro Uribe, Valencia's political godfather, released a video defending her as "authority with a maternal heart," attempting to soften her image even as he reiterated his fierce opposition to the peace accord.

Meanwhile, Abelardo de la Espriella, an ultra-right outsider candidate, announced José Manuel Restrepo, a former finance and commerce minister under Iván Duque, as his running mate. The choice positioned De la Espriella as a bridge to traditional conservative technocracy. Restrepo, in turn, sent conciliatory messages to Valencia, suggesting that despite their rivalry, the right might find common ground. The subtext was clear: the conservative vote was splintering, and the second round of voting in May would likely force difficult coalitions.

Underlying all these announcements was a darker current. Roy Barreras, a left-wing senator whose "Frente Amplio Unitario" coalition had performed poorly in the Sunday consultation, alleged that over 900,000 votes had been fraudulently altered or disappeared. He demanded a forensic audit and international oversight. The OEA's election observation mission, meanwhile, published its preliminary report, noting both improvements in electoral administration and new concerns that required attention. The allegations of fraud, whether substantiated or not, deepened the sense that the May 31 primary elections would be contested not just at the ballot box but in courts and in the court of public opinion.

President Gustavo Petro, constrained by law from campaigning directly, nonetheless attacked Valencia in a series of posts, accusing her of disguising hatred as love. "There are hatreds that disguise themselves as love," he wrote, a barbed reference to her recent statements about wanting to embrace both his supporters and the uribistas. The president's intervention, technically improper, underscored how much the sitting government felt threatened by the possibility of a rightward shift. As the candidates finalized their tickets and the campaign entered its formal phase, Colombia faced a choice between competing visions of the country's future—and a test of whether its electoral institutions could withstand the pressures of deep ideological division.
