As Colombia approaches the March 2026 legislative elections, the political landscape is shifting toward a high-stakes three-way struggle. The Chamber of Representatives, which relies heavily on regional “machinery” and local power brokers, is currently dominated by the Liberal Party (PLC). However, the rise of polarized national movements suggests a reshuffling of the top spots is imminent.

The Institutional Landscape
The Liberal Party (PLC) currently holds 33 seats in the Chamber, making it the largest single force. Yet, recent developments indicate a cooling of its dominance. Over the last few weeks, internal friction within the PLC has intensified as party leader César Gaviria continues to distance the collective from President Gustavo Petro’s “National Agreement.” This positioning is critical: by moving toward the center-right, the PLC is competing for the same voters as the Centro Democrático (CD) and the Conservatives, potentially capping its growth while maintaining a solid floor of regional support.
Meanwhile, the Pacto Histórico (PH) is actively working to consolidate its various movements into a single legal party. This move is designed to navigate the 15% threshold rules and maximize seat distribution under the D’Hondt method. If successful, the PH is expected to remain a top-two contender, fueled by the government’s incumbency and social spending programs in rural districts.
Why the Liberal Party (PLC) is the Primary Contender for 3rd
The case for the PLC landing in third place rests on the “squeeze” effect. On one side, the Centro Democrático is gaining significant momentum as the primary opposition vehicle, likely to surge from its current 16 seats to challenge for the first or second spot. On the other side, the Pacto Histórico maintains a disciplined, unified base. The PLC, while possessing the most robust regional network of “gamonalismo” (local political bosses), lacks the ideological fervor currently driving the two poles of Colombian politics. Historically, when the country polarizes, traditional “machinery” parties like the PLC and the Conservatives settle into the middle-tier positions, providing the necessary votes for a majority without leading the chamber.

The Competition: CD and the Conservatives
The Centro Democrático (CD) is the most significant threat to this ranking, but for a different reason: they are likely to finish higher than third. With the current administration’s approval ratings fluctuating, the CD is positioned to capture the “protest vote,” which often translates into a massive seat gain in the Chamber. The Conservative Party, currently holding 27 seats, faces a steeper uphill battle. They have struggled with a clearer identity crisis than the Liberals, often appearing as a junior partner to the CD, which may lead to a slight contraction in their seat count, leaving the 3rd place spot open for the PLC.
Key Triggers to Watch
The final ranking will likely be determined by two factors: the success of the Pacto Histórico’s unification and the ability of the PLC to hold its regional strongholds in departments like Antioquia and Santander. Any further fragmentation of the “Center” (Green Alliance and La U) would further solidify the PLC’s position as the dominant traditional force, even if it loses the top spot to more polarized movements.
Current data shows a strong consensus around the Liberal Party (PLC) taking the third position, with a probability hovering around 86%. This is backed by substantial volume compared to other candidates. The Centro Democrático follows at a distant 12%, while other traditional groups like MIRA-CJL and the Green Alliance show negligible traction in the current projections.
