2010 Colombian presidential election
Presidential elections were held in Colombia in 2010. They took place under a two-round system, with an initial vote held on May 30 and a second poll held three weeks later on June 20. A referendum proposal that would have allowed incumbent President Álvaro Uribe the opportunity to run for a third term was rejected by the Constitutional Court of Colombia in a 7–2 ruling on February 26, 2010. Because no candidate received a majority (more than one-half) of the votes cast in the May 30 poll, the candidates with the two highest vote totals competed in a runoff election on June 20: Juan Manuel Santos of the liberal-conservative Social Party of National Unity which unites supporters of former President Uribe, and Antanas Mockus from the Green Party. Santos won the election with 69% of the votes.
