Armed insurgent groups are threatening candidates, intimidating communities, and shadowing Colombia’s upcoming presidential election with a level of political violence that has election observers sounding the alarm.

Story Highlights

Colombia recorded 415 violent incidents against political, social, and community leaders in 2025, with attacks on political leaders rising from 39 to 59 percent of all cases.
Illegal armed groups control rural and peripheral territories, restricting campaign access and voter mobility ahead of the May 31, 2026 presidential election.
Political violence, rising crime, and the government’s failure to rein in armed insurgent groups rank as the top issues driving voter concerns this election cycle.
Election observers and international monitors are calling for coordinated candidate protection, targeted security deployments, and rapid responses to disinformation.

Violence Clouds Colombia’s Presidential Race

Colombia’s presidential election, scheduled for May 31, 2026, is unfolding against a backdrop of escalating political violence. The Atlantic Council reports that “the electoral environment has deteriorated in recent weeks,” with death threats against candidates and documented attacks on their protection teams highlighting what analysts describe as persistent and worsening security risks. ^[1] Outgoing President Gustavo Petro, elected in 2022 as Colombia’s first left-wing president, is constitutionally barred from seeking a second term, leaving the field open in a deeply polarized contest. ^[4]

Americas Quarterly reports that concerns over political violence, rising crime, and the government’s failure to control armed insurgent groups are considered the top issues in this election. ^[2] That framing reflects a broader reality: for many Colombians, particularly those in rural areas, the question of who governs the country is inseparable from the question of whether they can safely participate in choosing that leader.

Armed Groups Squeeze Rural Voters

Illegal armed groups exert territorial control over large swaths of Colombia’s rural and peripheral regions, and that control directly shapes electoral conditions. According to the Atlantic Council, these groups “constrain campaign access, restrict voter mobility, and increase risk of intimidation in territories with limited state presence.” ^[1] Candidates struggle to reach voters in these areas, and voters face pressure — sometimes explicit threats — from armed actors with a stake in the outcome or simply in demonstrating dominance over civilian life.

The scale of documented violence against political figures in 2025 underscores just how dangerous the environment has become. Colombia’s Electoral Observation Mission recorded 415 violent incidents against political, social, and community leaders last year. ^[1] More alarming is the shift in targeting: attacks specifically aimed at political leaders climbed from 39 to 59 percent of all recorded cases, suggesting armed groups are increasingly focused on disrupting political participation rather than engaging in generalized criminality. ^[1]

Two Conservatives Battle for a Chance to Stop the Left

On the candidate side, the race has taken shape around a high-stakes conservative contest. Americas Quarterly reports that two conservative candidates are competing for the right to face left-wing frontrunner Iván Cepeda in what could be a defining runoff. ^[2] The outcome of that conservative primary battle will likely determine whether Colombia continues on its current leftward trajectory or pivots back toward market-oriented, security-focused governance — a choice that matters not just to Colombians but to regional stability and U.S. interests in Latin America.

The International Republican Institute conducted a pre-election assessment mission focused on information integrity, civil society coordination, and voter access — areas that reflect genuine concern about whether Colombians will be able to make free and informed choices on election day. ^[3] The United States has also issued formal warnings regarding the integrity of Colombia’s electoral process, adding international weight to domestic concerns about whether the vote can be conducted fairly under current security conditions.

Resilient Institutions, But Real Risks Remain

Colombia’s electoral institutions have a track record of conducting elections even under difficult conditions, and the Atlantic Council acknowledges that resilience. ^[1] Proposed safeguards include coordinated candidate protection, targeted security deployments in high-risk municipalities, and rapid-response mechanisms for disinformation. ^[1] These are meaningful tools, but their effectiveness depends entirely on whether the government deploys them with sufficient reach into the peripheral territories where armed groups hold the most sway — and where the state has historically been weakest.

What makes this election particularly consequential is the combination of factors converging at once: a polarized electorate, a powerful left-wing candidate, a fragmented conservative field, deteriorating security conditions, and armed groups that have demonstrated both the will and the capacity to interfere. For American conservatives watching Latin America, Colombia’s election is a reminder that the battle between ordered liberty and authoritarian leftism is not confined to Washington — and that when governments fail to secure their own territory, ordinary citizens pay the price at the ballot box and beyond.
