In 2004, following a national debate about amending the constitution to allow for a second presidential term, a motion widely popular among Colombians and sought by the sitting President Álvaro Uribe Vélez, Mejía voted in favour of the re-election amendment and went against the official position of her party which opposed the re-elections of Uribe that demanded that all its members vote against it. For her vote, Mejía and other eight Liberal Senators including: Luis Guillermo Vélez Trujillo, José Renán Trujillo García, Víctor Renán Barco López, Jorge Aurelio Iragorri Hormaza, Piedad del Socorro Zuccardi de García, Dilian Francisca Toro Torres, Manuel Antonio Díaz Jimeno, and Flor Modesta Gnecco Arregocés, were suspended by the Disciplinary Tribunal of the Liberal Party for a period of ten months each; She was replaced in Congress on 28 August 2004 by Ernesto Zuluaga Ramírez, second-in-row of her electoral list.

In the national general election she received 55,087 votes, most of them from the Coffee-Growers Axis region, that represented 0.535% of the total national votes earning her a seat in the Senate.
