… Why might Trump’s narrow popular-vote loss in 2016 become a more dramatic rejection of the incumbent president?
Detailed new polling from Pew Research Center shows how the electorate has shifted away from Trump over the past four years.

Comparing the demographic data from that analysis to the results of a new national poll — in which Trump trails by 10 points — allows us to see both current support and how that support has changed.
