What divides the parties on this issue

This is where the governing coalition comes apart. On March 11, 2026, the president's electoral reform reached the floor and fell short of the two-thirds a constitutional change requires: Morena backed it with almost no defections, but most PT and PVEM deputies voted no. Two of its pieces are in the test, and on both Morena ends up at an extreme without its allies.

The first is how to fill the 200 proportional representation seats: with the best-performing district candidates instead of lists drawn up by each party leadership. Morena strongly agrees. The PVEM, which had made leaving the list system alone a condition, strongly disagrees, and the PT disagrees because its floor leader saw the change as a handicap for states with fewer voters. The PRI, Movimiento Ciudadano and SOMOS defend the mixed system as it stands. The crossover comes from the PAN: its leadership said in January 2026 that it could accept those deputies coming straight from the ballot, hence its agreement, even though in March it voted down the full package. The second piece, spending less public money on parties, leaves Morena as the only one in favor; the PT and the PVEM sit in the middle, open to a cut of up to half if shared out evenly, and the only ones opposed are the PAN, which first wants tighter oversight of how the money is spent, and SOMOS, which wants public funding to remain the main source.

On the other two questions the usual blocs return. The September 2026 amendment barring anyone who holds another nationality besides Mexican from governing the country or a state pits the coalition, in strong agreement, against the PAN, the PRI, Movimiento Ciudadano and SOMOS, in strong disagreement. On overrepresentation, the opposition and SOMOS want seat shares tied closely to votes; Morena, the PT and the PVEM have no document on it, so their disagreement is an estimate.

Seven positions in this theme are estimated: those three and all four of PAZ, registered in 2026 and still without a platform, whose documents call for reforming the party system and for transparency in how money is used, but do not address any of these four decisions.

1. Proportional-representation deputies should be chosen by direct vote, not from lists drawn up by the parties.

Of the 500 deputies, 300 are elected in districts and 200 by proportional representation, from closed party lists in five regional constituencies. The electoral reform rejected in March 2026 proposed changing that system.

Of the 8 parties with a position on this question: 2 in favor, 1 in between and 5 against.

2. Public funding for political parties should be cut.

Registered parties receive public money every year for their ordinary and campaign expenses, calculated by the INE as set out in law. The electoral reform rejected by the Chamber in March 2026 proposed cutting it.

Of the 8 parties with a position on this question: 1 in favor, 5 in between and 2 against.

3. No party should hold a larger share of seats in the Chamber than its share of the vote.

Today no party may hold more than 300 seats, or a share of seats more than 8 points above its share of the vote (article 54 of the Constitution).

Of the 8 parties with a position on this question: 5 in favor, 0 in between and 3 against.

4. Only people who hold Mexican nationality alone should be able to govern a state or the country.

To hold the presidency or a governorship, a person must be Mexican by birth. On September 22, 2026 the Chamber approved amending articles 82, 116 and 122 of the Constitution to also require holding no other nationality.

Of the 8 parties with a position on this question: 3 in favor, 1 in between and 4 against.
