2026 U.S. midterm elections and Mexico, Digi Mart USA News: Voters in the United States go to the polls on November 3 in midterm elections that will determine the balance of power in Washington and mark the second half of Donald Trump’s second term. Although the president is not on the ballot, the result will determine how much room he has to advance his agenda over the next two years.
For Mexico, the election carries particular weight because of its potential impact on migration, tariffs, the USMCA (T-MEC), security and border cooperation. This Tuesday, all 435 seats in the House of Representatives, 35 Senate seats and 36 governorships are being renewed, along with thousands of state and local offices.
Republicans hold majorities in both chambers, but Democrats are seeking to regain control. If they succeed, Trump would face greater obstacles in advancing some of his policies.
A Republican majority, by contrast, would give him a more favorable legislative setting during the final two years of his term.
The difference will be especially important on issues that directly affect Mexico, such as immigration policy, tariffs and border security measures.
California, Arizona, New Mexico and Texas, the four U.S. states that share a border with Mexico, are also holding gubernatorial elections.
These governments have influence over matters related to security, infrastructure, transportation and border operations. Texas draws particular attention with the contest between Republican Greg Abbott, who is seeking a fourth term, and Democrat Gina Hinojosa.
In Arizona, Democrat Katie Hobbs is seeking reelection. The outcome in these states could reshape the political landscape of a region where millions of people cross daily for work, commerce, family and tourism.
Trump’s immigration policy is one of the main points of tension between the two countries. His administration has pursued a harsher policy toward undocumented migrants, with detention and deportation operations.
More than 11 million people born in Mexico live in the United States, while the population of Mexican origin exceeds 38 million when descendants are included. Therefore, any change in U.S.
immigration policy could have direct consequences for millions of families on both sides of the border.
The economic relationship will also be under scrutiny. Mexico and the United States maintain one of the most important trade relationships in the world, with production chains deeply integrated in sectors such as automotive, electronics, industrial goods and agri-food.
Trump has used tariffs as a tool of trade pressure, and the bilateral relationship is also tied to the review of the USMCA. The new political balance in Washington could influence the White House’s negotiating room with Mexico and Canada.
The fight against drug trafficking is another central theme of the bilateral relationship. The Trump administration has hardened its rhetoric against Mexican organized crime groups and has placed drug trafficking and border security among its main priorities.
For Mexico, the electoral result will matter because it can shift the internal U.S. political debate on security and, with it, the conditions of negotiation between the two governments.
The midterm elections will not decide who occupies the White House: Donald Trump will remain president. What can change is the political power surrounding him.
A Democratic Congress could become a counterweight to his agenda; a Republican majority would give him greater room to advance his main policies. For Mexico, that difference could translate into different scenarios regarding deportations, tariffs, the USMCA, border security and bilateral cooperation.
Therefore, although the votes are counted in the United States, the result will have repercussions far beyond its borders.
Washington votes on November 3, and Mexico is watching closely who will hold the keys to power over the next two years.
