PRI-UDC Takes Commanding Victory

The PRI-UDC coalition won all 16 majority-rule districts in Coahuila's local congressional elections on June 7, according to preliminary electoral results (PREP).

The vote count showed the PRI-led coalition capturing 684,211 votes, or 55.03% of ballots cast, versus 325,824 votes (26.20%) for the PT-Morena coalition. The gap exceeded 29 percentage points. The outcome matters for Mexico because Coahuila remains one of the few states where the PRI maintains broad electoral appeal, and it reshapes the local congress balance ahead of 2027 elections.

Strong Turnout, Allegations of Irregularities

Civic participation exceeded 50% of the 2.5 million registered voters on the rolls, up sharply from 39% in the 2020 local election. Electoral officials installed 4,275 polling stations and reported no incidents during voting. Three opposition parties, the PAN, Citizens Movement, and Green Party, fell below the 3% threshold, jeopardizing their state registration and public funding.

In one district race, PRI candidate Verónica Martínez defeated Morena's Antonio Attolini by roughly 41 points.

Party Reactions

PRI national chairman Alejandro Moreno declared victory: "We won 16 of 16 local house seats and did so with a clear advantage." Governor Manolo Jiménez described the election as peaceful.

Meanwhile, Morena leadership, led by Ariadna Montiel, filed complaints with electoral authorities alleging irregularities, including a suspected vote-buying scheme involving QR codes and the detention of party activists in Frontera municipality. Morena demanded an investigation.

What Comes Next

Validation of certificates and allocation of the nine proportional representation seats will determine the Coahuila Congress composition in coming days.
