Trump's approval rating has hovered in the mid-30s percent range through mid-August 2026, with recent individual polls recording lows of 33 percent amid consistent double-digit net negatives. The dominant driver remains the U.S. military involvement in Iran that began in early 2026, which has disrupted global oil flows through the Strait of Hormuz, elevated gasoline prices, and sustained public concern that the conflict will extend indefinitely. Polling shows broad majorities across parties viewing the war as costly and lacking clear endpoints, while economic sentiment on inflation and cost-of-living metrics has deteriorated further. Approaching November 2026 midterms add pressure, as voters evaluate Republican congressional performance alongside the president's standing. Any near-term resolution of hostilities, fresh economic data releases, or shifts in partisan support could alter the trajectory before year-end.
