A Reuters/Ipsos poll released Monday showed public support in the United States for the military campaign in Iran has fallen to its lowest level since the early days of the conflict, with President Donald Trump's approval rating stuck at a record low.
According to the survey, only 31% of Americans said they support U.S. military action against Iran, down from 37% in March and 34% earlier this month. Notably, support among Republican voters also slipped to 69%, compared with 77% in March.
The ongoing war continues to weigh on Trump's standing. For the second consecutive poll, just 33% of respondents said they approve of Trump's performance as president—the lowest figure in the survey's tracking across his two terms.
Trump has defended the military campaign as necessary to prevent Iran from developing nuclear weapons. The conflict began on February 28 with U.S. and Israeli strikes on Iran.
However, the economic toll of the war remains a major concern for Americans. Iran has maintained a de facto blockade on oil exports from the region, helping push U.S. gasoline prices near record highs.
The Trump administration has also announced new commitments to increase economic pressure on Tehran. Treasury Secretary Scott Bessent said Monday that the United States will target all of Iran's revenue sources, including oil, to deter other countries and companies from doing business with Tehran—a campaign dubbed "Operation Economic Outcast."
The poll also showed a growing number of Americans expect the war to drag on. As many as 83% of respondents believe the conflict will persist for a long time, up from 80% earlier this month.
The prospect of a prolonged war poses a major challenge for Trump, who ran in 2024 on a promise to curb inflation and pursue an "America First" strategy avoiding overseas military entanglements.
Entering the sixth month of the conflict, gasoline prices are now over $1 per gallon higher than before the war, adding economic pressure ahead of the November midterm elections. Rising fuel costs could also complicate Republican efforts to protect their narrow majorities in Congress.
The poll showed independent voters leaning toward Democrats when asked which party they would back in the congressional elections taking place today. Among this group, 33% said they would choose a Democratic candidate, versus 19% who picked a Republican.
The Reuters/Ipsos survey was conducted over four days with 1,215 adults nationwide, carrying a margin of error of 3 percentage points.
