The Morena deputy race has begun, as President Claudia Sheinbaum’s party picks by opinion poll who will defend its majority in 2027.
Mexico’s governing party, Morena, has opened registration for those who want to run in the 300 districts of the lower house. Applicants can sign up online from 1 to 4 October 2026, ahead of the June 2027 election, El Universal reported.
A first step towards the 2027 ballot
Morena, short for the National Regeneration Movement, is the party of President Claudia Sheinbaum. Its national leadership published the call on the night of 29 September, Mexico City time.
Formally, the call is not for candidates. It invites applications for district coordinators of the party’s “Committees for the Defence of the Transformation and National Sovereignty”.
In practice, those coordinators are the people Morena expects to field as candidates. El Universal described the posts as open to anyone who aims to run for a federal deputy seat.
The “transformation” is the name Morena gives to its political project, launched under former president Andrés Manuel López Obrador.
The sign-up rules
Registration takes place only online, from 1 to 4 October 2026. The call covers the 300 district seats, not the 200 proportional seats filled from party lists.
Applicants must file an official CV with a recent photo. They must also name their state and electoral district, and list their professional, political and local community work.
A separate sworn statement bars people with final convictions for family violence or sexual crimes. People listed as overdue on child support, or sanctioned for political violence against women, are also excluded.
Polls decide, and losers cannot appeal
Every applicant signs a “letter of commitment” when registering, according to the documents El Universal obtained. It binds them to accept the party’s final decision.
The letter says the choice may rest on “surveys, polls or opinion studies”. The National Elections Commission, the party body that runs internal contests, will also assess each profile.
Signing up gives no right to the post, the letter adds. Applicants agree not to challenge the outcome, which gives the party leadership the last word.
Lessons from the governor contests
The call follows Morena’s selection of its state-level coordinators for 2027. That round ended on Monday, 28 September, with Cruz Pérez Cuéllar named for the northern state of Chihuahua.
The party had postponed the deputy call while it reviewed the requirements. Citlalli Hernández, Morena’s national elections coordinator, said the rules would differ from the state round.
One change concerns sitting deputies. Those who seek re-election will not have to take leave from Congress to compete, Hernández said.
Why sitting deputies pushed for different rules
Ricardo Monreal leads Morena’s group in the Chamber of Deputies. In August he asked that deputies seeking re-election not be forced to step aside.
He argued that taking leave would slow the work of Congress. By then, 41 of Morena’s 253 deputies had already taken leave at different times, he said.
Ariadna Montiel, the party’s national president, backed the idea of no compulsory leave. She said the party itself had proposed it.
The calendar ahead
The national electoral authority, known as the INE, set election day for 6 June 2027. Voters will renew all 500 seats in the Chamber of Deputies, the lower house of Congress.
Of those seats, 300 are won in single-member districts and 200 are shared out by proportional representation. Pre-campaigns, when parties pick their candidates, run from 4 January to 12 February 2027.
Parties must choose their district candidates by 19 February 2027. Official campaigns then run from April until 2 June 2027.
What it means beyond the party
Morena and its allies hold a two-thirds majority in the lower house, enough to change the constitution. The 2027 vote will decide whether that majority survives.
Polls replace an open vote of party members, which can keep internal disputes out of public view. The pledge not to appeal, however, leaves the final say with the leadership.
The number of applicants has not been published. Montiel has said the party has until December to define its coordinators, before pre-campaigns start in January.
For investors and residents, the make-up of the next Congress will shape the pace of reform. The district picks, due by December, will be the next test of Morena’s poll method.
