President Donald Trump's approval ratings have plunged to second-term lows in the low 30s per recent CNN, Economist, and RealClearPolitics averages, reflecting trader concerns over the past week's escalation in the Iran war, which has spiked gas prices above $4 per gallon and correlated historically with presidential popularity declines. A partial government shutdown has compounded economic unease, with inflation and foreign policy approvals also hitting new lows, even among Republicans and younger voters. Key upcoming catalysts include potential war de-escalation, shutdown resolution via continuing resolution, midterm election dynamics, and economic indicators like jobs reports, all of which could drive a rebound or further erosion through year-end.
