Approaching the first anniversary of his victory over Hillary Clinton in the 2016 election, Trump has an approval rating demonstrably lower than any previous chief executive at this point in his presidency over seven decades of polling. Fewer than 4 in 10 Americans — 37 percent — say they approve of the way he is handling his job.

Trump’s approval rating has changed little over the past four months, which have included tumultuous events, from hurricanes to legislative setbacks to indictments in special counsel Robert S. Mueller III’s investigation into the role Russia played in the 2016 campaign.

The president’s disapproval rating has reached 59 percent, with 50 percent saying they strongly disapprove of the job he is doing. While little changed since the summer, both represent the worst marks of his presidency.
