Mexico implements new candidate vetting and ballot protocols for 2027 elections

Mexican authorities and the National Electoral Institute (INE) are implementing new measures ahead of the 2027 midterm elections to protect electoral integrity and combat organized crime infiltration.

The government is designing a unique methodology to evaluate political aspirants for “reasonable risks” of links to criminal groups. This process, coordinated with the INE, will allow political parties to voluntarily submit precandidate lists for review by security and intelligence agencies, including the FGR and the Financial Intelligence Unit (UIF). President Claudia Sheinbaum emphasized that these reviews will rely solely on official Mexican institutional data.

Simultaneously, the INE has approved new guidelines regarding the handling of ballots that show no visible signs of folding. To address concerns about potential fraud or improper ballot insertion, the INE established a procedure where such ballots are not automatically validated or discarded. Instead, they are reserved for determination by the District Council, with all incidents documented in official records to ensure transparency and allow for legal challenges.

These actions follow a violent 2024 electoral cycle that saw dozens of politicians killed or kidnapped, prompting calls for stronger safeguards against criminal influence in the upcoming renewal of governorships and municipal presidencies.
