President Donald Trump’s job approval has declined steadily through the first half of 2026, reaching recent polling averages between 34% and 40% amid widespread public opposition to the U.S. military operation against Iran and rising costs for gasoline and consumer goods. Recent surveys show majorities across party lines viewing the conflict as a mistake, with gas prices up sharply since the campaign began and only limited Republican support for the administration’s economic management. These pressures have coincided with the approach of the November 2026 midterm elections, when control of Congress will hinge on voter turnout and economic sentiment. Historical patterns indicate that sustained net-negative ratings near or below −20 can intensify legislative gridlock and shape the policy agenda for the remainder of the term.
