Trump voters turn on Iran as devastating poll reveals 1 in 4 now think striking Tehran was a catastrophic mistake | 21 May 2026 | 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.
