President Donald Trump's approval rating has declined to second-term lows around 37-40% in recent national polls from CNN, Nate Silver's average, and others as of early April 2026, driven primarily by surging gas prices above $4 per gallon amid the ongoing Iran conflict and persistent high inflation. Polling averages show net disapproval nearing -20 points, with independents at -38 net in Quinnipiac surveys, reflecting voter frustration over economic handling (31% approval in CNN) and foreign policy (36% on Iran per Fox). No major rebounds have occurred in the past 30 days despite a recent national address on the war; historical precedents link presidential ratings closely to fuel costs and midterm pressures, with 2026 primaries starting in spring potentially amplifying scrutiny on legislative achievements like border security and spending bills.
