Mexico Readies Electoral Overhaul Targeting Costs and Representation Rules

Public forums fed proposals the administration plans to present to Congress in early 2026.

Overview

  • The Sheinbaum government and Morena caucus are preparing an electoral reform package for congressional submission.
  • The plan prioritizes lowering the overall cost of elections and cutting public financing for political parties.
  • The proposal keeps proportional representation but would reduce the number of legislators and change how Congress seats are allocated.
  • Topics under discussion include new rules for assigning plurinominal seats, eliminating OPLES, trimming party prerogatives, shortening timelines to form new parties, and potentially mandating voting.
  • Public debate is intensifying, with broad support for reducing party funding if equity is protected and warnings from critics like Lorenzo Córdova that the changes could marginalize opposition forces.
