Trump’s approval number reached a high point of 52 percent in early March amid positive economic indicators and congressional Republicans’ initial rollout of their plan to overhaul parts of the Affordable Care Act. As that process floundered and markets reflected new pessimism over the unified GOP government’s ability to deliver on promised tax cuts, support for the president has dropped among voters of all partisan leanings.

During the March 9-13 survey, 88 percent of Republicans supported of Trump’s job performance. In the new survey, 81 percent of GOP voters are still backing Trump’s work at the White House. There’s a similar drop in approval among Americans who said they voted for Trump in November, from 92 percent to 84 percent.

Support from independents has also dropped, from 43 percent in early March to 39 percent in the new survey. More than half of independents (53 percent) now disapprove of Trump’s handling of the job.
