The Liberal Party, a coalition comprising a cross-section of the center-left, and the leftist Polo Democrático have no chance of victory, although their support for a Mockus government would be important in forging a stable parliamentary majority. Conversely, legislative elections in March gave the Mockus-Fajardo ticket only minimal representation in the two chambers of Congress, implying that any government that they form would need all the legislative allies that it can find in order to enact its agenda.
此外，为选举蒙上阴影的并不是哥伦比亚武装力量游击队，而是由乌里韦候选人桑托斯和保守派候选人诺埃米·萨宁组成的右翼势力。由中左翼和左翼民主变革中心党组成的自由党竞选联盟几乎没有获胜的希望，但他们对莫卡斯政府的支持对于获取稳定的议会多数席位至关重要。相反，莫卡斯法哈多组合在三月举行的立法会选举中仅获得最低的议会两院代表席位，这意味着他们成立的任何政府都需要获得所有可能的立法盟友的支持，才能推行相关政策。
