President Trump’s approval has declined in October and November, after holding pretty steady July-Sept. There was steady decline Jan-Mar, then a sharper fall after announcing tariffs in April. Approval rose in May after backing off on tariffs. Then a small decline in June. Current decline is across most pollsters.

Gallup November Trump approval: 36% approve, 60% disapprove, a 5 point drop in approval and 6 point increase in disapproval since Oct. Several points below my approval trend across all polls which puts approval at 40.5%, disapproval at 56.1%
