Colombia's leftist ruling ​party and right-wing main opposition party won the most seats in the March 8 legislative elections but did not secure a majority, El Colombiano reported on the same date. In the presidential primaries, Paloma Valencia, a senator and ally of former President Alvaro Uribe, won the center-right nomination.

Fewer than half of the ⁠41 million Colombians eligible to vote did so. Colombians elected 102 senators and 182 deputies and voted in three presidential primaries. The leftist Pacto Historico got 22.9% of the votes for the Senate while the right-wing Democratic Center obtained 15.7%. While Valencia performed strongly in the center-right primary, Uribe did not win a Senate seat, marking his first defeat in national elections since first being elected in 1986. The legislative and primary elections occurred ahead of the May 31 vote for president.
