In 2010 Colombia held the general election. The center-right coalition strengthened ruling position and the Green Party rose as an independent third force. Manual Santos，the ruling Socialist Party of National Unity candidate，backed by President Alvaro Uribe，was elected president and took office in August 2010. His election should mainly attribute to his promise of securing Uribe’s political legacy. In the second round of election the right-wing coalition decisively adjusted the campaign strategy to increase its popularity. The Green Party and its presidential candidate Antanas Mockus lost the momentum due to a number of mistakes. It is expected that the Santos government will follow Uribe’s democratic security policy. On the other hand it needs to take actions to solve political and social problems left by decades of civil war.
