1. Trump’s net approval has declined in all 50 states since he took office
This isn’t totally surprising, as Trump’s net approval rating — the percentage of people who approve of the president minus the percentage who disapprove — has declined nationally since January 2017. But it’s still noteworthy. It often seems as if American politics is split between two immutable camps: Trump loyalists and Trump haters, and neither group ever changes its mind about anything. But the data here suggests more fluidity — and in Trump’s case, the movement is against him. Trump does have near-ironclad support (close to 90 percent approval, according to Gallup) among self-described Republicans nationally. But a Gallup poll conducted last year found that only about 40 percent of U.S. adults identify themselves as either Republicans or leaning toward the GOP. So that remaining 60 percent of the U.S. that identifies as Democrats and independents is likely where Trump has grown more unpopular.
