A fresh Politico poll reveals a significant erosion of support for the Iran war among President Trump's core MAGA base, as economic pressures mount and the conflict enters its fifth month. The survey, conducted July 13–15 among 2,061 respondents, shows that just 37% of voters who strongly back Trump now favor continuing the war despite potential rising costs at home—a steep drop from 50% in May.
Another 37% of these voters said they would support the war only if it does not increase consumer prices, up sharply from 19% two months ago. Meanwhile, 19% of MAGA voters now say the U.S. should end the war regardless of domestic costs, compared to 12% in the previous poll. The share of undecided respondents fell to 7% from 10%.
The poll's margin of error is plus or minus 2.16 percentage points. The findings underscore how the prolonged conflict in Iran is straining the patience of even Trump's most loyal supporters, many of whom were drawn to his 2016 promise to avoid foreign entanglements.
The Iran war has weighed heavily on the U.S. economy. According to AAA, the average price of a gallon of gas nationwide stood at about $4.06 on Wednesday evening, up from roughly $3.15 a year ago. That surge has become a central political vulnerability for the White House, as voters across the spectrum feel the pinch.
The erosion of support within Trump's base comes as prominent former allies voice criticism. Former Rep. Marjorie Taylor Greene (R-Ga.), once a staunch Trump supporter, blasted the president on Tuesday for a social media post in which he highlighted the death toll from the Iran conflict. “Trump is bragging about killing 18 US soldiers. That’s how I read this stupid post. The ‘peace president’ went to war and is killing and wounding our troops,” Greene wrote, ending her post with a vulgar acronym.
Trump's handling of the war has also contributed to a broader drop in his overall approval rating. A separate recent poll pegged his approval at just 36%, with a majority of Americans disapproving of his performance. The Iran conflict, combined with rising inflation and energy costs, is fueling discontent even among voters who previously gave him the benefit of the doubt.
The poll's timing—just days after Trump visited Dover Air Force Base for the return of four fallen troops—highlights the human and economic toll of a war that was never authorized by Congress. As the conflict drags on, the political calculus for the White House grows more precarious, especially with midterm elections looming.
The data suggests that the MAGA base, while still broadly supportive of Trump, is increasingly conditional in its backing of his foreign policy. The shift could force the administration to recalibrate its messaging or face a further erosion of support among the voters who matter most to the president's political survival.
