Presidential campaign in December 2023 Throughout 2023 different constituent sectors of the Broad Front announced their support for a possible candidacy of Cosse for the
2024 presidential primaries, including the most left-wing ones, such as the
Communist,
Socialist and
Revolutionary Workers' parties. On November 8, 2023, still in the position of Intendant, Cosse formally announced her candidacy. She had previously said in 2020 that she would not run for president if she was elected
Intendant of Montevideo. In late November 2023, she was polling at about 33% in national Broad Front primary opinion polls, second to
Yamandú Orsi. On December 10, she was officially nominated by the Congress of the Broad Front, along with Orsi,
Andrés Lima and
Mario Bergara, who later withdrew his candidacy. She announced that she would give her signature to promote the
constitutional referendum proposed by the
Plenario Intersindical de Trabajadores – Convención Nacional de Trabajadores to eliminate private pension companies. This sparked controversy because there was no consensus in the party on whether to support it or not. During the campaign, both former President
José Mujica and his wife
Lucía Topolansky, publicly criticized Cosse and stated that the Broad Front could lose the general elections if she were the presidential candidate. They later claimed that she could not beat the
National Party because outside of
Montevideo people "could not stand her", referring to the fact that Cosse focused her politics only on the capital. Cosse lost to Orsi in the Broad Front primary in June 2024, with 36% of the votes. She lost in the
Montevideo Department, which she was governing. However, she was selected by Orsi as his running mate for the
general election. On July 8, she resigned as Intendant of Montevideo after having requested a "leave" in March, and held a closing ceremony for her administration that was criticized as "populist". She was succeeded by Macerlo Zunino.
Vice presidential campaign Cosse was officially nominated for vice presidency by the Broad Front National Convention on August 3. She announced that she would not vote in favor of any of the
constitutional referendums up for popular consultation. Regarding the reform to allow nighttime police raids, she said that a Broad Front government would not apply the measure. Her statements sparked controversy due to the possibility of not respecting the Constitution which she later retracted. During the campaign she refused to participate in a debate between the vice-presidential candidates, thus rejecting proposals from the candidate for the
National Party,
Valeria Ripoll. Cosse became the vice president–elect after Orsi won the runoff of the
2024 general election. == Personal life ==
