Democrats seize both chambers of Congress in midterm rebuke of Trump

Democrats took control of both the House of Representatives and the Senate in the 2026 midterm elections, ending Republican majorities and marking a clear rejection of President Donald Trump's second-term agenda.

The results, finalized on 5 November 2026, give Democrats the ability to set the legislative calendar and conduct oversight for the remaining two years of Trump's term. Key races in states long considered Republican strongholds flipped, including a Senate seat in Texas.

President Trump acknowledged that the ongoing war with Iran played a role in the outcome. In remarks to reporters, he described the war's effect as “largely true” while defending the decision to launch it and stating he would “do it again.”

Vice President JD Vance went further in a post on X. He wrote that “the reason we lost is the war” and noted that Trump himself had said so the previous night. Vance listed ending the war, focusing on the cost of living, prioritizing America, and changing the relationship with Israel as steps needed to win back voters who supported Trump in 2024 but switched this cycle.

Exit polls and reporting linked the losses to voter frustration over the Iran conflict and the accompanying rise in gasoline prices. Democrats campaigned on ending the war and addressing household costs. The party now holds majorities in both chambers for the first time in years.

Markets reacted immediately. Oil prices fell sharply as investors priced in the possibility of reduced military pressure and progress toward talks on both the Iran and Ukraine conflicts. The Dow Jones Industrial Average rose, while semiconductor shares faced pressure over potential regulatory shifts.

Democratic leaders stated they would use the new majorities to rein in executive actions, including tariffs and military commitments. Republican figures, including some who had supported the Iran operation, faced questions about accountability. Defense Secretary Pete Hegseth drew particular criticism, with at least one Republican filing articles of impeachment.

The shift reorders Washington's balance of power. With Democrats controlling Congress, legislation on foreign policy, energy, and oversight of the Iran war will move under different leadership. Trump has signaled he intends to continue existing policies without major revision.

Voters in multiple states also elected new governors and state officials, including Deb Haaland as the first Native American woman to win a governorship. The full composition of the new Congress will shape the final two years of the administration and the early positioning for 2028.

The election outcome centers on concrete voter priorities around the war and its domestic economic effects. How the two parties respond to those priorities will determine the next phase of policy on Iran, energy prices, and congressional oversight.
