Nearly 60 million Mexicans on Sunday voted to elect their next president for a nonrenewable, six-year term. Former Mexico City head of government Claudia Sheinbaum won in a landslide, giving the ruling Morena party a continued hold on executive power.

But missing from the U.S. headlines is that Morena and its coalition partners could receive a qualified majority in both chambers of Mexico’s Congress once all the votes are counted. If this majority imposes unilateral changes to Mexico’s Constitution that undermine the country’s democratic institutions, the growing economic, political, and security crisis between the United States and Mexico would only deepen.
