FOX poll finds Trump approval hits new low as Iran war weighs on voters

President Donald Trump’s job approval has fallen to a new low, with several key demographics pulling back their previous support, according to a new FOX News poll released March 25.

The survey, conducted March 20-23 among 1,001 registered voters, found that 41% approve of Trump’s job performance, while 59% disapprove – the highest disapproval rating of either of his two terms. Nearly half of voters, 47%, said they strongly disapprove.

The findings mark a sharp decline from a year earlier. In March 2025, Trump held a 49% approval rating and 51% disapproval rating. The split represents an eight-point drop in approval over the past year.

Support has softened even within Trump’s Republican base. Eighty-four percent of Republicans expressed approval in the latest poll — down from 92% a year ago. The decline appears concentrated among Republicans who did not identify as “MAGA” in the latest poll. Their approval dropped 11 points over the past year, from 70% to 59%. By contrast, support among self-identified “MAGA” Republicans remains nearly unchanged — moving just 1 point, from 98% to 97%. 

Opposition remains overwhelming among Democrats, with 95% disapproving, while independents show broad dissatisfaction as well, with just 1 in 4 approving.

According to FOX’s crosstabs, net approval stands at -14 among men, -22 among women, -54 among black voters, and -44 among Hispanic voters. Independents register at a net approval of -50, while urban voters are at -32 and suburban voters at -20. Rural voters break even. 

Some of the steepest shifts have come in voting groups that Trump made massive gains with in the 2024 election. Hispanic voters, for example, have swung from a -4 net approval in December 2025 to -44 in the latest survey. White non-college men, once a strong base of support at +17 in March 2025, now register at -4. 

Iran war emerges as major drag on approval

The poll suggests the Iran war is weighing on Trump’s standing with voters. A majority of respondents, 58%, oppose the current U.S. military action, including 4 in 10 who are strongly opposed, while 42% support it. Republican voters back the action 77% to 23%, but support drops sharply among independents at 28% and Democrats at just 12%. Women oppose the war at higher rates than men, 62% vs. 55%. 

Voters also expressed deep skepticism about the war’s trajectory. Fifty-two percent said the military action is not going well, and roughly 7 in 10 expect the conflict to last months or longer. At the same time, 59% believe the White House is focused on issues beyond core U.S. national security interests. While 58% of voters rated the U.S. military’s performance as excellent or good, 44% believe the operation has made the U.S. less safe.

Disapproval of Trump’s handling of Iran stands at 64%, up from 57% in January, and just 36% now approve. On foreign policy overall, 62% disapprove and 38% approve.

Other polls show similar trends

The latest FOX findings align with other recent national surveys showing Trump’s approval at or near the lowest levels of his second term, as Zeale News previously reported. A Reuters/Ipsos poll completed March 24 found Trump's overall approval at 36%, and a Quinnipiac University poll conducted March 19-23 found Trump at 38% approval overall and 56% disapproval. 

Recent polling has also shown significant erosion in support among men, particularly young voters, Zeale News previously reported. Trump won men’s support by 13 points over former Vice President Kamala Harris in the 2024 election. He is now 7 points underwater among male voters, marking a 20-point swing.
