Colombian Voters Elect New Congress for 2026-2030 Legislative Term; Party With Largest Senate Block Still Only 26%

The new members of Congress will take office on July 20, the official start of the new legislative term.

On March 8, Colombia elected the Congress that will exercise legislative authority during the 2026–2030 term. From more than 3,200 candidates, voters chose the 102 senators (upper house) and 182 members of the House of Representatives (lower house) who will make up the country’s legislative branch.

According to preliminary reports from the Registraduría Nacional del Estado Civil (RNEC), with 98.4% of polling stations counted, equivalent to 19,220,365 votes tallied, the new Congress has been defined electorally, however, it should be noted that these seat projections correspond to the official preliminary count, which still must go through several formal procedures before the final results are certified.

How the Senate Race is Shaping Up?

The Pacto Histórico, the party of current President Gustavo Petro, obtained around 22% of the vote (4,402,601), which would allow it to increase its representation from 20 senators in the current legislature to approximately 25 seats in the next term.

In second place is the Centro Democrático, the party of former President Álvaro Uribe, with about 15% of the vote (3,020,459), potentially increasing its representation from 13 to 17 seats.

The Partido Liberal would rank third with 13 seats (2,268,658 votes). It would be followed by the Alianza por Colombia, led by the Green Party, with 10 seats (1,899,096 votes), and the Partido Conservador, also with 10 seats (1,859,493 votes).

Other wins in the Senate include Party of La U (9 seats), Cambio Radical (7), the Ahora Colombia coalition (5), which backs presidential candidate Sergio Fajardo, and Salvación Nacional (4), the movement of presidential candidate Abelardo de la Espriella. The two remaining seats correspond to the special indigenous constituency.

In terms of losses in representation, the Partido Conservador would be the most affected, losing five of its current 15 seats. Cambio Radical would lose four, the Greens three, La U two, while Liberals and Ahora Colombia would each lose one seat.

Among the prominent figures who would be left out of the new Senate is former President Álvaro Uribe, who occupied position number 25 on his party’s list and would not obtain a seat if the Centro Democrático secures only 17 seats. Green Party senator Angélica Lozano, known for promoting legislation related to transparency, would also lose her seat.

Likewise, movements such as the coalition that supported Juan Daniel Oviedo and the Partido Oxígeno, led by former presidential candidate Ingrid Betancourt, who was kidnapped for years by the now-defunct FARC guerrilla group, would fail to surpass the minimum threshold required to obtain Senate representation (3% of the total vote).

On the other hand, the performance of the Salvación Nacional movement, led by presidential candidate Abelardo de la Espriella, stands out. In its first participation in a congressional election, the party would surpass the electoral threshold and secure four senators.

What About the House of Representatives?

The allocation of seats in the House of Representatives follows a different process from that of the Senate, making it difficult to project the final distribution in the early stages of the vote count.

This is because the calculation is conducted department by department, once the RNEC determines the seat allocation formula and electoral quotient in each of the 32 States and the Capital District of Bogotá.

According to report number 45 from the RNEC, with 99.03% of votes counted, the main parties have obtained the following preliminary nationwide results:

• Centro Democrático: 2,551,706 votes.
• Partido Liberal: 2,101,877 votes.
• Partido Conservador: 1,967,996 votes.
• La U: 1,044,778 votes.
• Pacto Histórico: 913,990 votes.
• Cambio Radical: 803,721 votes.
• Alianza Verde: 654,071 votes.
• Salvación Nacional: 436,365 votes.

Because the House of Representatives elections involve parties, movements, and coalitions with strong local and regional influence, several smaller political organizations are expected to win seats, as they must surpass regional thresholds rather than a national one.

The Highlight: a Fragmented Congress that Will Require Coalitions

With the preliminary distribution of seats in both the Senate and the House of Representatives, projections suggest that Colombia’s next president will need to govern through legislative coalitions, as has occurred under President Gustavo Petro and his predecessors.

Presidential candidates Iván Cepeda, of the Pacto Histórico, and Paloma Valencia, of the Centro Democrático, would begin the next political phase with the largest congressional blocs, although neither would have enough seats to govern alone.

Traditional parties such as the Liberal, Conservador, Cambio Radical, and La U, which together could account for more than 40% of the new congress, have not yet decided which presidential candidate they will support, a situation similar to what occurred in the previous election. These parties could therefore become kingmakers, capable of facilitating, or blocking, governability depending on the alliances and coalitions they choose to form.

For that reason, the coming weeks are expected to be marked by intense political negotiations, as presidential contenders attempt to build alliances that would allow them to secure legislative support.

For candidates such as Sergio Fajardo, whose Ahora Colombia coalition would obtain only five senators, or Abelardo de la Espriella, whose Salvación Nacional movement would have four, the challenge will be significantly greater.
