On March 11, 2026, the PVEM's caucus joined the PT in defeating one of President Claudia Sheinbaum's reforms: 49 of its deputies voted no and 12 voted yes. It was the electoral reform, which would have handed the proportional-representation seats to the candidates with the most votes instead of drawing them from party lists, and the Greens had asked for that system to be left alone. By our count of this legislature's votes, it is the only time a majority of the caucus split from Morena. That episode produces its loneliest answer: no other party rejects so firmly the idea of filling those seats at the ballot box, and Morena sits at the opposite end.
Otherwise, the Greens keep step with their partners. On 27 statements both the PVEM and Morena have a documented stance, and on only two do they land on opposite sides: those seats and nepotism. With the PT, across the same number, there is a single clash. That is why its most distinctive theme, "Justice and the judiciary," at 2.62 points, matches its two allies' exactly: all three voted together for electing judges at the polls in 2024, for the 2025 changes to the Amparo Law and for shielding constitutional amendments from the Court. On a five-step scale, its answer thus sits, on average, more than two and a half steps from the rest.
"Institutions and corruption" (2.1 points) shows the subtlest difference. When the Constitution was amended so that no one can inherit an office from a relative, the PVEM asked for the rule to wait until 2030 and did not join the internal ban Morena imposed on itself for 2027; in the quiz it is the only party at the far end of opposing an earlier start, with the PT one step closer to the center. It also rules out reviving INAI, Cofece and the other autonomous bodies it voted to abolish. On immunity it stays in the middle: in 2025 a Green senator filed an "Out with immunity" bill while its deputies backed a committee report that spared a deputy from losing his.
Technology is its trademark on "Security and armed forces" (1.96 points). Its 2024 platform calls for drones, facial recognition and artificial intelligence against crime, and it is the only party backing this at full strength; Morena and the PT sit one notch lower. It goes further than Morena on drugs: its platform speaks of legalizing and regulating the market, Morena's only of opening a debate. The green label shows, with caveats: it wants polluters to pay in proportion to the harm, prefers renewables and voted to ban GM maize, but also to make Pemex and the CFE state-owned public companies.
Its 45 answers split into exact thirds, 15 in agreement, 15 at the midpoint and 15 in disagreement, and 17 fall at one end of the scale. It differs least from the rest on "Work and pensions" (0.29 points). Two in five answers, 18 in all, are estimated, mostly in two themes: all three on education and four of the six on rights, including abortion, euthanasia and adoption by same-sex couples, which its documents do not address. Question by question, it is closest to Morena (86%) and the PT (84%), and furthest from the PAN (49%).
