After the tenure of president Ernesto Samper, a faction of the Liberal Party was not happy with the new social democratic route the party was moving towards. As such, a more right-wing faction of the party split away and formed Radical Change. However, it did not run for either parliamentary or presidential elections during the 1990s.
Uribe government
In the 2002 elections, the party won two seats in the Senate and seven in the chamber of representatives. The party joined a coalition with the government of Álvaro Uribe, and voted in favor of the re-electionist project; this involved changing sections of the constitution that prevent a president from running for a second term. 2006 was their best electoral year. They became the 4th largest political group in Congress with 15 senators and 18 representatives. They remained in coalition with the Uribe administration and supported his candidacy for re-election. German Vargas Lleras, then leader of the party and senator, became one of the Senate's most active voices.
Breakup
The biggest party in Congress proposed to change the constitution, yet again, to allow the president to run for a third term. The party was divided between those who wanted a second direct re-election for a third term and those who were against it. Vargas Lleras was among those opposed. Although a third term was deemed unconstitutional by the Supreme Court, the damage was done and those who still supported Uribe quit the party to run for Congress in the 2010 parliamentary elections with the newly-formed U party. The party suffered big blows in 2010, losing votes and members in both chambers: seven Senators and two Representatives. Vargas Lleras then ran as the candidate in the 2010 presidential election, finishing in third place in the first round. The party then joined the first-round winner, Juan Manuel Santos, along with the Liberal Party and the Conservative party to form the "National Unity Pact" that would work together for the next four years.
The party assisted the government with most of their agenda in Congress. When the peace talks with the FARC began, the party offered their approval and criticized then ex-President Álvaro Uribe for opposing dialogue. In 2014, the party participated in the parliamentary elections and joined in a coalition with Santos for his reelection. Vargas Lleras was named the vice-presidential candidate. Although the party received fewer votes than in 2010, they added one senator, but lost one seat in the lower chamber. Santos won the second round of the presidential elections that year, making the vice-presidential position the highest the party had ever achieved.
