This Sunday, March 8, 2026, Colombia will hold one of the most significant electoral events of the year’s political calendar. In addition to electing a new congress, voters will participate in the so-called Interparty Primaries, a mechanism through which political parties select their candidates for the presidential election scheduled for May 31.

According to the political analysis website Razón Pública, these consultations seek to “build broad coalitions composed of parties, movements, and independent candidacies.” In practice, they allow different political sectors to determine through open voting who will represent each coalition in the presidential race.

Political parties seek to boost their chances in the presidential race or strengthen their leverage in potential coalition negotiations.

In total, three separate primaries will take place, each with its own ballot. Citizens may participate in only one of them by requesting the corresponding ballot when voting for Congress.

The first is the “Solutions Primary: Healthcare, Security and Education,” made up of parties from the political center. In this contest, former Bogotá mayor Claudia López faces independent lawyer Leonardo Huertas. According to the latest Invamer poll, López is the clear frontrunner, with a projected 92.9% voting preference, compared with her only opponent.

The second consultation represents the political right and includes nine pre-candidates in the so-called “Grand Primary for Colombia.”

Among the contenders are former ministers of previous governments Juan Carlos Pinzón (Defense), Mauricio Cárdenas (Finance), and David Luna (Information Technologies); former Antioquia governor Aníbal Gaviria; former Bogotá mayor Enrique Peñalosa; journalist Vicky Dávila; and three senators representing their respective parties: Juan Manuel Galán (Nuevo Liberalismo), Juan Daniel Oviedo (Con Toda con Colombia), and Paloma Valencia (Centro Democrático).

Polls consistently identify Paloma Valencia as the favorite to win the primary. The Invamer poll projects her with 41.6% of the vote, Atlas Intel 44.4%, and Guarumo-EcoAnalítica 40.6%, while the firm Gad3 also places her first but with a lower estimated vote share of 17%. Valencia has been campaigning nationwide accompanied by former president Álvaro Uribe Vélez, the leading figure of the Centro Democrático, and previously won her party’s internal selection process through a member survey held on December 15.

The third primary corresponds to the coalition known as the “Front for Life,” made up of left-wing candidates, although without the official backing of current President Gustavo Petro, who under Colombian law is prohibited from participating in electoral politics or promoting candidates.

Candidates in this race include Héctor Elías Pineda, a former member of the M-19 guerrilla movement (the same group Petro once belonged to); Edison Lucio Torres of the Partido de los Trabajadores (Worker’s Party); and independent candidate Martha Viviana Bernal.

Former senator Roy Barreras; and embattled former mayor of Medellín Daniel Quintero Calle registered through the Movimiento de Autoridades Indígenas de Colombia. Polls by Guarumo-EcoAnalítica (47.6%) and Invamer (68.1%) place Daniel Quintero as the leading candidate of this Primary. However, the firm Atlas Intel did not measure this coalition, arguing that it did not surpass the statistical threshold required.

What comes next in the political landscape after the Primaries?

According to Razón Pública, “once the March 8 voting concludes, the political landscape will enter a phase of critical decisions. The results will determine alliances and realignments ahead of the presidential first round.”

Across the political spectrum, the winners of each consultation will attempt to consolidate support to compete against other candidates who registered directly without participating in the consultations. These include Abelardo de la Espriella, a conservative lawyer and businessman who registered through citizen signatures; Iván Cepeda, the official candidate of the Pacto Histórico coalition led by President Petro and currently leading voting-intention polls; and Sergio Fajardo, who registered with the party Dignidad y Compromiso.

Under Colombia’s electoral Law (1475 of 2011), political parties may still modify or withdraw candidates until March 20. After that date, the presidential campaign will move toward the first round scheduled for May 31. If no candidate secures an absolute majority of the vote (50% plus one), the two candidates receiving the highest number of votes will compete in a runoff election on June 21, where the candidate with a simple majority will be elected president.
