From its inception, UDEMO emphasized an ideology centered on the restoration of peace, national unity, and territorial integrity, reflecting its commitment to rebuilding a cohesive and stable Democratic Republic of the Congo.

On December 12, 2005, Nzanga Mobutu announced his candidacy for the upcoming presidential election, held in July 2006.

Later in 2006, during the second round of the election, UDEMO transitioned into a political platform and joined the Alliance of the Presidential Majority (AMP), a coalition supporting President Joseph Kabila.

The party maintains a strong base of support in the northwestern province of Équateur, particularly in Gbadolite.

In 2023, UDEMO joined the Sacred Union of the Nation (USN), the presidential majority coalition under President Félix Tshisekedi.
