Summary
Trump’s approval rating has turned negative for the first time in his second term, with FiveThirtyEight showing 47.6% approval and 47.9% disapproval (-0.3% net).
This shift happened faster than in his first term. The drop coincides with new tariffs on Mexico, Canada, and China, fueling economic concerns.
Despite a well-received congressional address (69% CNN approval, 76% CBS/YouGov), his ratings continue to decline.
The short answer is basically Trump supporters are overrepresented in the watchers. Biden also got numbers in the high 60s.
