Trump's Iran War Leaves Voters Paying at the Pump

Noor Dubow, a Columbus trucking dispatcher who regularly voted Republican, says Donald Trump's decision to go to war with Iran has pushed him toward Democrats. “Where are the Republicans in Congress?” he asked. “Why aren't the Republicans holding Trump accountable?” That question now hangs over a conflict that has driven up fuel costs and become a liability for Republicans trying to retain control of Congress.

Who Pays for the War

Higher gasoline and diesel prices have raised costs across the economy, Republican strategists privately acknowledged. Diesel prices stayed near record highs, complicating races in Iowa, Kansas, Ohio and Texas. The national average gasoline price remained above $4 per gallon. Voters increasingly linked the war to higher grocery prices and travel costs, according to internal campaign polling described by the strategists.

Trump has brushed aside those costs as he campaigns to preserve Republican control of both chambers. He called the war a “little detour,” said it was nearing an end, and threatened more intensive bombing after the election. He has called higher gas prices a temporary cost worth paying to disarm Iran.

At a weekend rally in Michigan, Trump said he had no regrets about starting the war. “Somebody said, 'If you had it to do again...' I said, 'Are you kidding? I thought gas would be double or triple. And it's a small price to pay for taking a nuclear weapon away from maniacs.'” People far from the decision-making table pay the price at the pump.

The Political Machinery

The AP-NORC poll published the previous week found voters from both major parties wanted the next Congress to focus on affordability and end the war. The conflict, described as nearly eight months old, has affected the global economy. It has also spread: Iran-backed Houthi rebels attacked Saudi Arabia's oil infrastructure and airports, then a Saudi-led coalition carried out deadly attacks on Houthi-held territory in Yemen.

Over the weekend, the State Department said it would reduce staffing at four U.S. embassies in the Middle East after receiving intelligence that Iran had increased efforts to target U.S. personnel in the region and elsewhere. The war's costs have also become a campaign problem for the party that controls the executive branch and wants to keep its power in Congress.

Early in the summer, five Republican strategists involved in key races or advising campaign leadership told the Associated Press they saw warning signs that the war could hurt candidates if it didn't end soon. Trump and White House officials appeared more confident in June after an interim ceasefire agreement with Tehran, but the agreement unraveled. Later, campaign officials in some battleground races said internal discussions showed House districts Trump had won easily in 2024 becoming competitive. The strategists spoke anonymously because they weren't authorized to discuss internal party data.

A Ballot Box Under Pressure

Oil prices peaked in May, fell in June and rose again in September, when Trump threatened escalation, then backed off and suggested an agreement might be close. After Labor Day, strategists said internal polls showed voters increasingly tying the war to household costs. Trump called claims that the war was driving an affordability crisis a Democratic “hoax” or “scam.” The strategists said internal campaign polling showed voters hadn't bought that argument.

Some Republican voters still support the war, though fuel costs test their patience. Clay Coey, 59, an auctioneer from DeWitt, Michigan, said he cringed while filling his 2010 Chrysler Sebring. Still, he was willing to pay temporarily to address what he considered a major security threat. “Do I like it? No, I drive this old beast,” he said. “However, there does come a point in time where you have to sit here and say, what is worth the cost?”

Elizabeth Marlett, 61, of Moville, Iowa, said she wished Trump hadn't set a timeline and wanted the U.S. military to act more forcefully to make Tehran capitulate. She continued to support him. “We need to support our commander in chief, even if things take longer than expected,” said Marlett, a small-herd beef rancher in northwest Iowa. “That's life, and we can't run from something we've started.”

Sean O'Brien, 21, a student at Auburn University in Alabama, said Trump's decision left him “very disillusioned.” After attending the Conservative Political Action Conference earlier in 2026, he said he was reconsidering his political allegiance. “At the moment, I expect to vote Democratic,” he said. O'Brien described himself as an independent. The midterms are Nov. 3. But the choices on the ballot don't change who made the decision to start the war—or who faces its costs.
