Where Mexico's parties agree and where they clash

For each party and each statement, the test stores a position on a scale of one to five. With 45 statements in the main test and eight parties, that makes 360 positions. Read statement by statement rather than party by party, they draw a different map: where the parties share common ground and where they do not.

The measure is simple. For each statement we take the highest and the lowest position among the eight parties and calculate the gap between the two (our calculation). A gap of zero would mean that all of them think exactly the same. A gap of four means that one party "strongly agrees" and another "strongly disagrees".

How the gaps are distributed

On 14 of the 45 statements there is at least one party at each end of the scale: almost one in three. On none do all eight think exactly the same, but on five the gap is a single point. Counting only sourced positions, the 14 with the maximum gap remain 14.

Not all positions are equally solid: 93 of the 360 are not based on a specific document and are marked as estimated. Partido PAZ has 33 and SOMOS 11, because they were registered in 2026 and do not yet have an election platform or deputies; their positions are provisional until they file their platforms, in the first half of January 2027. They are followed by the PVEM (18), Morena (9), the PT and the PRI (7), the PAN (5) and Movimiento Ciudadano (3). When a majority depends on estimated positions, we say so.

Where there is broad agreement

Eight statements have six or more parties on the same side. On five of them, almost every position has a source (at most one is missing):

• "Polluters should pay environmental taxes according to the damage they cause." All eight agree; the PVEM and PAZ strongly. It is the only statement on which all eight are on the same side with every position documented. The PVEM has proposed since its 2024 platform that "the polluter pays", and SOMOS and Movimiento Ciudadano propose "green taxes".
• "The minimum wage should keep rising above inflation every year." All eight agree; the PT and the PRI strongly. In September 2024, the Chamber passed an amendment to Article 123 of the Constitution that bars setting the minimum wage below inflation. PAZ's position is estimated.
• "Prices for staple grains should be set by the market, without government guaranteed prices." Seven parties disagree (SOMOS strongly) and none agrees; the PAN's neutral position is estimated.
• "Mexico should prioritize renewable energy over oil and gas, even if it costs more at first." Six agree; Morena and the PT are neutral, because their platforms call both for the energy transition and, in Morena's case, for consolidating Pemex and the CFE; in the PT's, for much more natural gas production.
• "Social programs should be aimed mainly at those who have least, rather than being for everyone." Six disagree, in favor of programs for everyone; only SOMOS agrees, and the PAN is neutral.

On the other three, estimated positions weigh more: removing the immunity of deputies and senators (six in favor, two of them estimated; the PRI against), adoption by same-sex couples and trans people changing their name and sex through an administrative procedure (six in favor on both; PAZ and the PAN against, with estimated positions). On adoption, only four parties have a sourced position, and all four are in favor.

And there are statements on which nobody is on the opposite side, even if several parties are neutral. No party opposes the government using facial recognition cameras and artificial intelligence to prevent crime (five in favor, three neutral, all sourced), and none supports Mexico stopping undocumented migrants from crossing the country on their way to the United States (four against and four neutral; three of the eight positions are estimated).

Where the parties split into two blocs

The line that recurs most often separates the governing parties from the opposition. On nine statements, Morena, the PT and the PVEM are on one side and Movimiento Ciudadano, SOMOS, the PRI and the PAN on the other; on six of them, all seven are at the end of the scale, and all are sourced except PAZ's. They are almost always reforms that the governing bloc voted through in the Chamber since 2024:

• "The National Guard should return to civilian command, outside the Ministry of Defense."
• "The election of judges, magistrates and Supreme Court justices by popular vote should be reversed."
• "The suspensions that judges grant in amparo proceedings against laws and government acts should be limited."
• "Constitutional amendments should not be open to challenge before the Supreme Court."
• "Autonomous bodies, independent from the government, should be restored for transparency and economic competition."
• "Only people who hold Mexican nationality alone should be able to govern a state or the country."

The other three are automatic pretrial detention depending on the offence (Morena, the PT and the PVEM strongly disagree that a judge should always decide it; the rest agree, all sourced), the armed forces no longer running airports, trains and customs, and no party holding a larger share of seats than of votes; on these last two, several of the governing parties' positions are estimated. PAZ sits in or near the middle on all nine, and its position is estimated on seven.

Lines that do not always follow the same blocs

On the other seven statements with the maximum gap, the blocs change:

• "Proportional-representation deputies should be chosen by direct vote, not from lists drawn up by the parties." Morena strongly agrees and the PAN agrees; the PVEM strongly disagrees, and the PT, Movimiento Ciudadano, SOMOS and the PRI disagree. In March 2026, most PT and PVEM deputies voted against the President's electoral reform that proposed it.
• "The ban on relatives succeeding an officeholder should already apply in the 2027 elections, not from 2030." Movimiento Ciudadano strongly agrees; Morena, the PRI and the PAN agree; the PT disagrees and the PVEM strongly disagrees.
• "Planting genetically modified maize should remain banned in Mexico." Morena, the PT, the PVEM and the PRI strongly agree, Movimiento Ciudadano agrees; the PAN strongly disagrees.
• "Private companies should be able to compete with Pemex and the CFE (the state oil and electricity companies) on equal terms." The PAN strongly agrees and the PRI agrees; Morena, the PT and the PVEM strongly disagree; Movimiento Ciudadano and SOMOS are neutral.
• "An annual tax on large fortunes should be created." The PT and Movimiento Ciudadano strongly agree, SOMOS agrees; the PAN strongly disagrees; Morena is neutral. The positions of the PVEM, the PRI and PAZ are estimated.
• "Mexico should keep high tariffs on products from China and other countries that have no trade agreement with it." Morena and the PVEM strongly agree; the PT disagrees and Movimiento Ciudadano strongly disagrees; the PRI and the PAN, which abstained in the December 2025 vote, are neutral.
• "Abortion should be legal nationwide during the first 12 weeks of pregnancy." Movimiento Ciudadano and SOMOS strongly agree; Morena, the PT and the PRI agree; PAZ disagrees and the PAN strongly disagrees.

So Morena, the PT and the PVEM, which will run together in 2027, are on the same side (all three in favor, against or neutral) on 23 of the 45 statements; the PAN and the PRI, allies in 2024, on 28; and Movimiento Ciudadano and SOMOS on 36.

By topic

The parties clash most on justice, with the maximum gap on all three statements, and on security, elections and institutions, which hold all nine statements of the line between government and opposition. Broad agreement is found mainly on energy and the environment, wages and farming. Education has neither maximum gaps nor large majorities, and it is also the topic with the most estimated positions: 13 of 24, because several parties have not taken a stance on teacher evaluation, full-day schools or minors on social media.

Which parties are most alike

The same data show which parties are closest to each other. The table gives the seven closest and the three most distant of the 28 possible pairs, by average gap across the 45 statements:

The closest are Movimiento Ciudadano and SOMOS, which are never three points or more apart (11 of SOMOS's positions are estimated; counting only the 32 statements where both have a source, the average gap is even smaller, 0.38). Morena matches the PVEM and the PT exactly on 28 statements. The PRI, which ran in coalition with the PAN in 2024, is closer to SOMOS and Movimiento Ciudadano than to the PAN, from which it is separated above all by GM maize, abortion and parliamentary immunity. The most distant are the PAN and the three governing parties: only four identical positions, and at least three points apart on 15 or 16 statements.

What this means for the test

A statement on which all parties agree does not help tell them apart: answering it gives almost the same score with all of them. What separates the parties are the statements with large gaps. That is why it is worth answering them even when it is hard to decide.

It also explains a common impression at the end of the test: if your result gives several parties similar percentages, you may agree with them on what they share and sit in the middle on what divides them. With parties as alike as Movimiento Ciudadano and SOMOS, or Morena, the PT and the PVEM, a tie is likely. When the second or third party is 3 points or less behind the first, the test offers you up to eight tiebreak questions, chosen from the 15 in the tiebreak bank (not counted in this analysis) because they best separate those parties.

All the parties' positions side by side are in the party comparison table, and you can compare two of them, for example Movimiento Ciudadano and SOMOS, Morena and the PT or the PAN and the PRI. Where each party falls on the compass is explained in "Who is on the left and who is on the right of the compass". And to see which one your ideas match most closely, take the test.
