In 2006, the party took part in the parliamentary elections, in which it won 30 out of 166 deputies and 20 out of 100 senators. Three years later, more than half of the congressmen from the Radical Change Party changed their standing towards the Party of the U, which resulted in it becoming Colombia's largest political party.[citation needed]
For the 2010 presidential elections, Party of the U chose former Defense Minister Juan Manuel Santos as a presidential candidate and Governor Angelino Garzon as a vice presidential candidate. Juan Manuel Santos was elected with 69% of the vote in the runoff. The Party also obtained 27 seats in the Senate in the 2010 congressional elections.
In 2012, the Uribistas and former President Alvaro Uribe along with Francisco Santos Calderon decided to form their own separate party, the Democratic Center. This was the result of constant intervention and criticism from former President Alvaro Uribe towards his presidential successor Juan Manuel Santos. The announcement of peace negotiations with the FARC and the Colombian Government was a partial factor that led to the fragmentation. Nevertheless, the party did not suffer high-level defections towards the Democratic Center. It came first in the Senate elections, followed in second place by the Democratic Center led by Alvaro Uribe who then became a Senator.[citation needed]
In 2021, political leaders from multiple parties formed a coalition called the Historic Pact for Colombia. After the election of President Gustavo Petro in 2022, Party of the U allied with the Liberal Party and the Conservative Party.
Ideological platform
The Programmatic Declaration (Declaración Programática) is the official ideological platform of the party.
The Social Party of National Unity supports the development of the welfare state and recognises the family as the base of society.
The Party supports the implementation of a market-based economy.
It promotes globalisation, emphasising education, science, and technology as key pillars that can help Colombia succeed in a global market.
The Party supports decentralisation and more autonomy of the regions. Currently, the Caribbean Region is the first to begin the process to obtain more autonomy.
President Santos has also claimed that he supports Tony Blair's Third Way approach.

Social National Unity Party: A conservative party that favors liberal economic policies, Partido de la U was the core of Uribe's legislative coalition during his second term and led the failed effort to clear the way for Uribe to pursue a third term in 2010.
