After 2002 Moreno Rojas focused on consolidating the Independent Democratic Pole, a leftist political movement that included ANAPO and of which he was made party president.

In 2005 Moreno Rojas was defeated by Antonio Navarro Wolff during the Democratic Pole's convention to appoint a presidential candidate.

On 8 July 2007, he was elected as the candidate for the Alternative Democratic Pole after defeating the frontrunner in the opinion polls, María Emma Mejía.

During his campaign he proposed the construction of an underground rapid transit system to increase the city's public transport capacity and reduce commuting time and crowding.

On 3 May 2011, the Inspector General of Colombia, Alejandro Ordoñez decided to suspend Moreno for three months, due to alleged omissions on public works executions.

[3][4] On 2 August 2011, the Inspector decided to extend the suspension for three more months, claiming that the case against Moreno has not been resolved yet, and more time is required to achieve a resolution.
