Mexico's Sheinbaum proposes constitutional ban on dual nationals for top offices

Left-wing President Claudia Sheinbaum told reporters that a Mexican president should have exclusive loyalty to Mexico, unveiling a constitutional amendment to forbid dual citizens from holding the presidency or any state governorship. The proposal builds on recent changes that let the National Electoral Institute cancel elections deemed influenced by foreign forces. Sheinbaum pointed to the election of U.S. citizens as heads of state in Colombia and Ecuador as a warning of expanding far-right, U.S.-linked influence in Latin America.

While Morena senators describe the measure as essential to prevent leaders from "selling out" Mexico, opposition figures and conservative PAN members warn it may be used to entrench Morena's dominance and restrict the rights of Mexican migrants abroad. The debate reflects broader concerns about foreign interference and the balance between national security and democratic openness.
