In the lead-up to the submission of Claudia Sheinbaum's electoral reform to the Congress of the Union, the Green Party announced its approval of nearly all aspects of the initiative. Manuel Velasco, the coordinator of the Green Party in the Senate, stated that their agreement spans between 90 to 95 percent of the proposal. This marks a significant moment as the party shows willingness to support key measures of the reform, suggesting a unified approach towards the upcoming electoral changes in Mexico.

Specifically, Velasco indicated that the Green Party would back Sheinbaum's proposal to eliminate plurinominal legislators in the Senate, opting instead for a system where representatives are elected through popular vote in the Chamber of Deputies. This approach, as explained by Velasco, aims to ensure that candidates who perform best during elections, including the most competent second-place candidates, gain access to legislative positions. The party's strategy indicates a readiness to engage with the proposal's finer points and suggests a collaborative effort to refine the electoral landscape in Mexico.

However, Velasco acknowledged that there remain contentious elements in the reform, particularly around how representatives will be elected and the criteria for success. The mention of a "debate" over the election of candidates by circumscriptions indicates that while there is substantial agreement, there are still discussions to be had regarding the specifics of the electoral process, reflecting the complexities involved in achieving a consensus on this critical reform.
