President Donald Trump’s approval rating has sunk to its lowest point since he took office, with only 35 percent of Americans saying they viewed the job he’s done favorably, according to a poll released Wednesday.

The new Marist poll found that 55 percent disapprove of Trump after seven months on the job.

Trump saw a sizable dip in his polling numbers among “strong Republicans,” from 91 percent in June to 79 percent, which analysts said shows a crack in the base on which the president leans heavily.

“While Republicans are still largely in Trump’s corner, the cautionary tale for the president lies in the softening of support at his base,” said Dr. Lee M. Miringoff, director of the Marist College Institute for Public Opinion. “Since his numbers among Democrats and independents are weak, a crack among his most ardent supporters is something Trump can ill afford.”

Pollsters conducted the survey between Aug. 8 and Aug. 12, the day violence broke out before a white nationalist rally in Charlottesville, Virginia. Three people were killed and scores went home — or to the hospital — battered, bruised, and cut.
