President Donald Trump's approval rating is once again sliding following a mid-April bump, according to the latest Quinnipiac University poll released on Wednesday (10 May). The poll, conducted 4-9 May, puts the president's approval rating at 36%.

The latest poll revealed Trump's disapproval rating was recorded at 58%. According to CNN, the interviews were conducted ahead of the news that the president had fired FBI Director James Comey on Tuesday (9 May).

Trump's approval rating had reached 40% in a mid-April poll that was conducted after he authorised a missile attack on a Syrian air base.

However, the latest survey showed Trump's approval rating reverting to its previous position from a poll released on 4 April, when he was recorded at 35%.

The Quinnipiac University poll showed Trump losing significant support among a key supporter demographic: white respondents without college degrees. CNN noted that the demographic has consistently supported Trump and is a rough representation of the white working class.

Trump is also losing support among independent voters, the poll found. His approval rating among independent voters declined from a negative 38-56% on 19 April to a negative 29-63% in the latest poll.

A larger majority of voters also hold more negative opinions about Trump's personal qualities, according to Quinnipiac. The poll found that 61% believe he is not honest, 56% believe he does not have good leadership skills and 59% believe he does not care about average Americans. More than two-thirds do not view Trump as being level headed or a strong person.

A small majority do believe Trump is intelligent, 56% to 41%.

"There is no way to spin or sugarcoat these sagging numbers," Tim Malloy, assistant director of the Quinnipiac University Poll. "The erosion of white men, white voters without college degrees and independent voters, the declaration by voters that President Donald Trump's first 100 days were mainly a failure and deepening concerns about Trump's honesty, intelligence and level headedness are red flags that the administration simply can't brush away."

Gallup's daily approval rating poll, meanwhile, shows Trump at just 38%.
