Midterm Upset Puts War Powers on the Congressional Clock

The November 3 midterms handed Democrats control of both chambers of Congress, but President Donald Trump retains the power to order military action against Iran. Two Senate races, in Mississippi and Alaska, remained too close to call on Wednesday, November 4. The election shifted control of the legislature; it did not end the war or transfer command of the military.

The vote, and the machinery behind it

Voters punished Republicans amid concerns about living costs, the Iran war and government corruption, according to Associated Press polling cited by Iran International. Other reporting cited tariffs and Trump's focus on White House renovations. Charles Hall, executive director of the North Carolina Soybean Producers Association, said steep energy costs for farmers were “really just leading to despair.” Hall said voters were “voting against something,” adding that farmers were “probably voting against high diesel prices.”

Sina Toossi, senior non-resident fellow at the Center for International Policy, described the demand as “relief from the war's economic costs, not more war.” Council on Foreign Relations senior fellow James Lindsay said the Republican losses went “well beyond Iran,” and linked them to voters' sense that life had become less affordable and to higher gas and diesel prices tied to the war.

Vice President JD Vance put the political cost plainly: “The reason we lost is the war. The president himself said so last night.” He cited the war, the economy and a desire to “change our relationship to Israel” as factors in voters switching sides. Vance urged Republicans to ask whether losing Senate control “for the next 6 years” had been worth it.

Trump called Vance's assessment “largely true because it drove the gasoline up a little bit short term,” then defended the decision to attack. “Because long term, it's the only answer. You can't let Iran have a nuclear weapon,” he said. Asked when the war would end, Trump replied: “Whenever I wanted to. But it's got to be done right, because they can't have a nuclear weapon.” He said he would launch the war again and that he would have “done nothing different.”

A purse, not a stop button

The incoming Congress takes office on January 3, 2027. Democrats will hold oversight and spending powers, but Trump retains the presidency and veto power; overriding a veto requires a two-thirds majority in both chambers. The Senate is projected at 56 seats for Democrats, including two independent allies, and 44 for Republicans. Sixty votes are needed to pass legislation.

Chuck Schumer, the Senate Democratic leader, said, “This war must end. It must end,” and pointed to Congress's “power of the purse.” Hakeem Jeffries, the House Democratic leader, called the conflict a “reckless and costly war of choice in Iran,” saying it raised fuel and fertilizer costs and contributed to higher prices for groceries and other goods. Democrats have discussed a measure intended to make Trump end the war or obtain congressional authorization. Their planned first 100 hours also include bills intended to reverse Trump policies.

That is a legislative lever, not an immediate halt to military command. Brian Katulis, a senior fellow at the Middle East Institute, said “it will be business as usual” before January, noting executive power over national security and war-making had grown across successive administrations. Mohamed Chebaro said the new congressional balance would not impede Trump in the near term and warned that a president without a compliant Congress “could be even more dangerous.”

Rival governments, civilian costs

U.S. and Iranian negotiators have held indirect talks, primarily mediated by Qatar and Pakistan. Trump has not ruled out renewed strikes, and RFE/RL reported that he said the United States still had to “take care of” one or two more targets, including a suspected nuclear site. Iran International reported that U.S. officials said the military was preparing for a possible resumption of major combat operations, including deploying additional assets to the region.

Iranian officials, meanwhile, cast the Democratic victory as a defeat for Trump while warning that a change in Congress might not alter U.S. policy. Supreme Leader Mojtaba Khamenei said anyone expecting a fundamental change because one party replaced another was “gravely mistaken.” Mohsen Rezaei, secretary of Iran's Supreme National Security Council, wrote that Iran had handed Trump a “POLITICAL DEFEAT in Washington,” and warned that anyone who took on Iran would pay a price “from the battlefield to their own doorstep.”

Iran International reported that commentators on Iranian state television and state-aligned media discussed possible retaliation against military and energy infrastructure. Tehran Municipality-affiliated Hamshahri newspaper published a map of Europe and said Iran's armed forces were updating potential targets “without geographical limitations.” These threats sit alongside the U.S. administration's stated readiness to resume combat: rival authorities speak in the language of deterrence while ordinary people face the consequences of decisions made above them.

Democratic control may constrain funding from January, Trita Parsi of the Quincy Institute for Responsible Statecraft said, but the election doesn't itself end the conflict. Sina Toossi said escalation offered no clear path to victory and risked further damaging Trump's presidency, while diplomacy offered a possible way out. The immediate question is whether lawmakers use their spending powers before another strike—or let the machinery keep running.
