Trump's approval rate at new low; slip in support among base: Poll

President Trump's approval rate has hit a new low.

Thirty-three percent of registered voters in the U.S. approve of the job Trump is doing as president, according to the poll conducted by Quinnipiac University, which reports a margin of error or 3.4 percentage points.

The poll’s findings also mark a new high for the president’s disapproval rating, which now stands at 61 percent.

Trump’s approval rating has decreased seven percentage points since Quinnipiac’s previous poll published on June 29. Trumps’s disapproval rating has increased 17 points since January with a similarly sized decrease in undecideds since then.

It may come as no surprise that Democrats are less likely to approve of Trump’s performance in office. Only 2 percent of Democrats say they approve of how Trump is handling his job.

But support among his base has also dipped.

Fifty percent of white voters without a college degree, a group that was instrumental in Trump's victory in 2016, now disapprove of the president's job performance. About one in four registered voters in his own party don’t support Trump: His approval among Republicans is down to 76 percent, the poll found.

Fifty-four percent of registered voters say that they are embarrassed to have Trump in office, while 57 percent believe he is abusing his presidential powers. Voters also responded negatively to questions about the president’s personal demeanor, with 71 percent saying he is not level-headed.
