Party switch to Morena and gubernatorial candidacies On 5 March 2018, Díaz Mena announced his resignation from the PAN and that he would become a member of
National Regeneration Movement (Morena), declaring that the state party had become a "rich kids' club" and calling out party leaders for leading the "decomposition" of the institution, saying that if the party's founders came back to life, they would be disappointed at its current state. Twelve days later, Morena and the other parties in the
Juntos Haremos Historia coalition nominated Díaz Mena as their gubernatorial candidate. On election day, Díaz Mena pulled 20.45 percent of the vote, placing third behind PRI candidate
Mauricio Sahuí Rivero and the winner, PAN candidate
Mauricio Vila Dosal. Díaz Mena contended again for the
governorship of Yucatán in the
2 June 2024 election, representing the Morena-led
Sigamos Haciendo Historia coalition. This time he won. ==References==
