The 2018 Mexican general election was the fifth presidential election PT had participated in. Its candidate for the Presidency was Andrés Manuel López Obrador as PT formed a coalition with left-wing National Regeneration Movement and right-wing Social Encounter Party. Background On 24 June 2017, the PT approved to stand for election in 2018 in an electoral alliance with MORENA, however the coalition was not officially registered before the National Electoral Institute, the electoral authorities of the country. From MORENA, the alliance was facilitated as a result of the decline of the PT candidate Óscar González Yáñez, who resigned his candidacy requesting the vote in favor of Delfina Gómez Álvarez, standard-bearer in the state elections of the State of Mexico in 2017. At first, there was speculation about the possibility of a front grouping all the leftist parties: MORENA, PRD, PT and Citizens' Movement. However, Andrés Manuel López Obrador rejected any kind of agreement due to political differences, especially after the elections in the State of Mexico, when the candidates of the PRD and MC continued with their campaigns refusing to support the candidate of MORENA. At the end of November 2017, the leaders of MORENA and the PES announced that they were in talks to form a possible alliance. In this sense, Hugo Eric Flores Cervantes, President of PES, said, "We don't negotiate with the PRI, we have two options, go alone or with MORENA." Confirmation On December 13, the coalition between Morena, the PT and the PES was formalized under the name Juntos Haremos Historia. Following the signing of the agreement, Andrés Manuel López Obrador was appointed as a pre-candidate for the three political formations. It is a partial coalition that will promote López Obrador as a presidential candidate and, with respect to the legislative elections: MORENA will have to choose candidates in 150 federal electoral districts and 32 districts to the Senate; 75 deputies and 16 senators for PT and 75 deputies and 16 senators for the PES. The alliance has received criticism as it is a coalition between two leftist parties with a formation related to the evangelical right. In response, the national president of MORENA, Yeidckol Polevnsky, mentioned that her party believes in inclusion, joint work to "rescue Mexico" and that they will continue to defend human rights, while Hugo Eric Flores Cervantes, national president of the PES, mentioned that "the only possibility of real change in our country is the one headed by Andrés Manuel López Obrador "and that his party had decided to put" on the right side of history."
