Midterm Rebuke Can't Stop Trump's Iran War Powers

The Democrats’ victory in the November 3, 2026, US midterm elections won them control of both chambers of Congress, but it didn’t give them an automatic veto over President Donald Trump’s military decisions. The new Congress convenes on January 3, 2027. Until then, and beyond it, Trump retains the presidency, veto power and substantial executive and military authority.

That gap between voters’ verdict and the machinery of war is the story. About six in 10 voters said the United States made the “wrong decision” by taking military action against Iran, according to the Associated Press Voter Poll of more than 100,000 people. Yet lawmakers can’t simply end the campaign by winning seats. Congress can investigate and influence military funding; overriding a presidential veto requires two-thirds majorities in both chambers.

The ballot and the battlefield

Voters also weighed the cost of the war at the pump and the grocery counter. About six in 10 were “very concerned” about gasoline and diesel prices, and roughly two-thirds of that group voted Democratic. About one-third said the war was “crucial” to their congressional vote, while roughly half cited cost of living or government corruption.

Iowa Sen.-elect Josh Turek described what voters told him: “Wherever I went, I heard the same thing. They would say, Josh, I'm struggling just to keep food on the table, keep a roof above my head, pay my electric bill. And with this war in Iran, I'm struggling just to keep gas in my tank.”

Trump acknowledged the war contributed to Republican losses, but defended the decision to attack Iran. “We had no choice. You can't let Iran have a nuclear weapon,” he told reporters. Asked when he would end the war, he replied: “Whenever I wanted to. But it's got to be done right, because they can't have a nuclear weapon.”

Vice President JD Vance wrote on X: “The reason we lost is the war.” House Democratic leader Hakeem Jeffries called it Trump’s “reckless and costly war of choice in Iran” and said it raised fuel and fertiliser costs. Senate Democratic leader Chuck Schumer said, “This war must end. It must end.” Their promised leverage, however, runs through Congress’s “power of the purse,” not an immediate switch that ends military action.

Hormuz: pressure from both capitals

Iranian officials framed the election as a rejection of Trump’s war. Parliament Speaker Mohammad Bagher Ghalibaf wrote on X: “Conscience or the cost of living, Americans said no to war, and we endorse this message.” He also warned that if Washington ignored public opposition, “it will learn our 'no' comes with a nightmare.”

Iran’s Supreme National Security Council chief Mohsen Rezaei called the result “a strategic defeat on the battlefield and in the Hormuz – and a political defeat in Washington.” At the same time, Iran’s IRGC said two oil tankers and a tugboat caught fire in separate incidents in the Strait of Hormuz and claimed it had seized two US Lucas-type drones. Those claims weren’t independently verified in the reports.

The United States imposed a blockade on Iranian ports and helped tankers cross the strait. US Central Command said it had helped Gulf countries export 1.5 billion barrels of oil through Hormuz since the summer. Iran had severely restricted traffic through the waterway, which normally carries about one-fifth of global oil consumption. Each side’s moves land on civilians and economies far beyond the rooms where officials make them.

No electoral shortcut out

The Associated Press poll found that nearly all voters who backed Democratic House candidates considered going to war the “wrong decision”; roughly eight in 10 Republican House voters called it the “right decision.” The election changed control of Congress, not the president’s authority to order military action.

US officials were weighing renewed strikes, continued sanctions and negotiations. The US military was preparing for a possible resumption of major combat operations, while Qatar sought backing for a draft agreement to prevent escalation and potentially restart direct negotiations. No breakthrough had emerged; the sides remained divided over Iran’s nuclear programme, sanctions and arrangements involving Hormuz.

Iran’s supreme leader, Mojtaba Khamenei, dismissed the idea that a change in party control would change US policy: “Those who still harbour even the slightest hope that the behaviour of the hegemonic system might change through partisan or factional shifts ... are seriously mistaken.” In Washington, the vote gave Democrats more oversight and legislative influence. It didn’t dissolve the apparatus making war, or guarantee that those who voted against it could stop it.
