Héctor Serrano Cortés of the Green Party proposed using polygraph tests for public office aspirants in San Luis Potosí [1].

The proposal seeks to address the influence of organized crime in the electoral process. By implementing these tests, officials aim to identify and exclude "narcocandidatos"—individuals with ties to drug trafficking organizations—before they can secure positions of power.

Serrano Cortés said the measure is intended to shield the elections and protect the integrity of the democratic process [1]. The initiative targets candidates across various levels of government in the state of San Luis Potosí, where the presence of criminal elements in politics has become a critical concern.

The use of polygraphs as a vetting tool is a drastic step toward ensuring that those elected to office are not operating under the influence or direction of cartels. This approach focuses on the preventative stage of the election, attempting to filter out compromised individuals before they are officially registered as candidates [1].

While the proposal aims to increase transparency, it introduces a new layer of scrutiny for those entering public service. The Green Party representative said the goal is to ensure that the leadership of San Luis Potosí remains independent of criminal interests [1].

The proposal seeks to address the influence of organized crime in the electoral process.

This proposal reflects the growing desperation of Mexican regional governments to decouple state administration from organized crime. While polygraph tests are often criticized for their reliability in legal settings, their proposal here serves as a political signal that the state is attempting to establish a 'hard line' against the infiltration of cartels into the legislative and executive branches.
