The claim states that polling numbers have been trending downward for the *past year*. The provided web search results indicate that while the approval rating declined after the Iran War began, the evidence also notes that the rating has been 'holding relatively steady over the past week' and discusses ongoing dissatisfaction with cost of living, but it does not provide a comprehensive, consistent trend analysis covering the entire 'past year' to confirm a sustained downward trend. The evidence suggests fluctuation and recent stability, making the blanket statement of a year-long downward trend misleading.
