Colombia's Presidential Debate: Petro Leads as Election Tensions Rise

Four candidates took the stage on a Monday evening in late May, six days before Colombia would choose its next president. Gustavo Petro, the leftist senator and former Bogotá mayor, arrived with bodyguards holding bulletproof shields. Federico Gutiérrez, the right-wing ex-mayor of Medellín, came with his own security detail. Rodolfo Hernández, a 77-year-old businessman who defied easy political categorization, and Sergio Fajardo rounded out the field. The debate, broadcast live at 7:30 p.m. across El Tiempo and Semana—Colombia's two largest news outlets—would reach millions through YouTube, Facebook, Instagram, and Twitter in the final stretch before voting on May 29.

Petro led the polls at 41 percent, a commanding position that nonetheless fell short of the majority needed to avoid a runoff scheduled for June 19. If he won, he would become the first leftist president in a nation historically governed by conservative and liberal elites. Gutiérrez trailed at 27 percent, though he remained the most likely challenger in a second round. Hernández, the outsider, hovered close behind, his appeal rooted partly in his distance from traditional power structures. The debate would cover the terrain that mattered most to voters: security, education, employment, the economy, agriculture.

But the campaign's final week was shadowed by something darker than policy disagreement. Death threats had circled the leading candidates. Petro now spoke in public wearing a bulletproof vest, encircled by armed guards with ballistic shields. On Saturday night, a green laser had been pointed at Francia Márquez, Petro's running mate and an Afro-Colombian environmentalist, as she delivered remarks in Bogotá. Her security team rushed her from the stage and canceled the event. The prosecutor's office opened an investigation. Márquez addressed it directly the next day: they wanted to instill fear, she said, the same fear that had haunted Colombia's people for generations. Gutiérrez, too, reported intimidation. The specter of political assassination—five presidential candidates had been murdered in Colombia during the twentieth century—hung over the race.

A second anxiety had taken root in the final days: suspicion of the electoral machinery itself. In March legislative elections, nearly 400,000 votes cast for the left had gone uncounted in the initial tally, only to surface later and shift the balance of power in Congress. Petro's coalition gained three additional seats as a result, becoming the largest force alongside the Liberals. Now, with the presidential vote days away, rumors circulated about possible problems with the software used to count ballots. Some whispered that the head of the National Registry—the body overseeing elections—might resign or that voting itself could be postponed.

On Saturday night in Barranquilla, Petro went public with his alarm. They were attempting a coup against the popular vote, he declared. The government was planning to suspend the elections, to dismantle the institutions managing the process. He called an urgent meeting with other candidates for Monday to discuss the threat. The Interior Minister, Diego Palacios, shot back on Twitter: such claims were absolutely false, he wrote, and candidates should stop spreading misinformation. The National Registry's chief, Alexander Vega, offered his own assurance on Sunday: the presidential election would be legitimate and transparent. The attacks on his institution, he said, amounted to an unjust and false narrative of fraud.

Yet the tension was real. A diplomatic source acknowledged the suspicions had been circulating for days and suggested Petro might be trying to prevent a coup by exposing it publicly. An election postponement seemed nearly unthinkable in a country as legalistic and committed to democracy as Colombia, the source cautioned—but the atmosphere was thick with strain. Petro had delivered his hundredth campaign speech that Sunday in central Bogotá, near the mayor's office he had occupied from 2012 to 2015, with Márquez beside him on stage. He spoke of change without revenge, of breaking the cycle of war, of writing a new blank page of freedom. Gutiérrez held his own rally in Medellín that same day, warning against the kind of reckless leap that had damaged Venezuela and Nicaragua, against surrendering Colombia to populism.

Abroad, more than 970,000 Colombians eligible to vote had already begun casting ballots. The debate on Monday would be their last chance to hear the candidates lay out their visions before the nation decided whether to make history or hold the line. The stakes were clear. The atmosphere was electric and dangerous.
