President Donald Trump is facing a brewing mutiny from American voters over his aggressive stance on Iran, an exclusive Daily Mail/JL Partners poll can reveal.In a devastating blow to the White House, more than one in four voters, 26 percent, who backed Trump in 2024 have now turned on the administration's military campaign, declaring that the launch of military action against the Islamic Republic was the wrong move.The findings come at a perilous moment, as a clear nationwide majority of 52 percent of all registered voters now condemn the military intervention as a mistake. Only 33 percent of Americans still view the strikes as the right choice. And fewer than half of the country backs the decision to go to war with Iran in general. Just 36 percent of US voters say they actually support the American decision to pursue military action in Iran when looking back, compared to nearly half, 49 percent, who are actively opposed.The public's appetite for further conflict has completely evaporated, with voters signaling deep resistance to any escalation and expressing serious dissatisfaction with diplomatic efforts.The poll shows that the US has received a net negative (-14) effectiveness rating from the public for its performance in the Iran ceasefire negotiations. Only 32 percent of Americans rate the administration's performance as effective, compared to 46 percent who brand it ineffective.
