A new AP-NORC poll finds that President Donald Trump’s approval rating on the economy has slumped over the past month as the Iran war drives prices higher.

Donald Trump’s approval rating on the economy has slumped over the past month as the Iran war drives prices higher, according to a new AP-NORC poll, with even Republicans showing less faith in his leadership.

The findings from The Associated Press-NORC Center for Public Affairs Research show a president who is struggling with unfulfilled promises to tame inflation and testing Americans’ patience with a conflict in the Middle East that has dragged on longer than expected.

Trump’s approval rating on the economy dropped to 30% in April from 38% in a March AP-NORC poll. A similarly low share of U.S. adults, 32%, approve of the president’s leadership on Iran, which is unchanged since last month.
