NBC News' Decision Desk Poll measured Trump's approval at 37% — a second-term low — with 63% disapproving overall, including majorities unhappy with his handling of inflation and the Iran war. The survey of 32,433 adults (March 30–April 13) also found Republican enthusiasm slipping: GOP approval fell 4 points since early 2026, while strong disapproval of his Iran war handling hit 26% even among Republicans. The core findings are well-sourced and have been corroborated by multiple news outlets including USA Today and Washington Examiner, though the post omits that energy prices tied to the Iran conflict and broader economic sentiment may be driving these numbers more than Trump's policies alone.
