A survey released last week finds a dip in support for President Trump in one of his key bases. It's the latest in a string of low approval numbers.

In the survey conducted in early May, 22 percent of Black voters said they approved of the job Trump was doing, while 69 percent disapproved, giving him a net approval rating of -47. Trump's net approval ratings among Black voters in polls conducted in June and July were -54 and -64 respectively.

According to polling by Civiqs, which has compiled survey responses in all U.S. states throughout the president's term, Trump's approval rating is declining among those who did not vote for him in the last election, suggesting he is not winning over previous dissenters.

President Donald Trump's approval rating by some measures hit lows at the end of July. The administration has been hit by the Epstein issue for weeks.

Trump’s average approval rating for the second quarter of his second term, April 20-July 19, is 40% in Gallup polling, compared to a 39% average in the second quarter of his first term but below second-term averages for every post-World War II president.
