A new NBC News poll finds 55% of voters believe President Donald Trump's policies have worsened economic conditions, compared with 26% who say they have improved them and 18% who see little effect. A Decision Desk HQ polling average put Trump's approval rating at 39.7% and disapproval at 58.9% on Sunday evening, revising the previously reported NBC figure of 41% approval. Inflation and the cost of living ranked as the most important issue for 28% of respondents, followed by government corruption at 18%, threats to democracy at 16% and jobs and the economy at 9%. Sixty-two percent said the Iran war was not worth it, while 33% disagreed. The findings represent a warning for Trump and Republicans ahead of the midterms, as the party debates how to address high prices and weak economic ratings. The poll surveyed 1,000 registered voters from Sept. 11-15 and has a margin of error of plus or minus 3.1 percentage points.
