U.S. support for military action against Iran fell to 31% in a Reuters/Ipsos poll, down from 37% in March and 34% earlier this month. Support among Republican respondents dropped to 69% from 77% in March. President Donald Trump's approval rating held at 33% for a second consecutive survey, matching the lowest level recorded across his first and second terms. The conflict, which began on February 28 with US and Israeli attacks on Iran, has also raised economic concerns. Iran has maintained a de facto blockade of oil exports from the region, pushing US petrol prices near record highs and to more than $1 per gallon above prewar levels six months into the conflict. Secretary of the Treasury Scott Bessent said the US would target all of Iran's revenue sources, including oil, under a campaign called "Operation Economic Outcast." Eighty-three percent of respondents expected the war to last for an extended period, up from 80% earlier this month. Among independent voters, 33% said they would support a Democrat in a congressional election held today, compared with 19% for a Republican, creating added pressure for Republicans ahead of November's midterm elections. The poll surveyed 1,215 US adults over four days and had a margin of error of 3 percentage points in either direction.
