By comparison, last month's national NBC/WSJ poll had Trump's overall approval rating at 40 percent.
Six months after serving as the president, Obama had 59 percent approval rating and Clinton had 45 percent approval rating, the poll said. But among Republicans, one-third think Russian Federation tried to influence the election outcome, and fewer than one in ten think Trump's associates sought to help them.
"It's surprising it's not more. The poll also raises concerns about Trump's inability to get much done".
Trump, of course, calls the poll "inaccurate" while also claiming that "almost 40 percent is not bad at this time".
Overall, 48 percent of those polled said they "disapprove strongly" of the current United States president's performance in office.
Some 48 percent now feel the country's leadership is weaker than it was when Trump took office and only 27 percent feel it is stronger.
Among Republicans, 38 percent of those polled said Trump's conduct has been unpresidential, a view shared by 48 percent of white evangelical protestants reached by the poll and 55 percent of white men without a college degree who responded to it.
Would you say that the more you hear about Trump, the more you like him?
The WSJ/NBC survey comes amid other poor polling for the President.
Not only is Trump stunningly unpopular, but his support has already been reduced to base levels, and the bad news for this White House is that there is plenty of room for him to drop. Twice as many of those surveyed preferred the Obamacare health program as favoured Republican plans to replace it. About a quarter volunteer either "neither", say they want something else or offer no opinion. The number of Americans who prefer Obamacare is more than twice those who prefer the GOP changes.
Even among Republicans, just 41 per cent say his tweets are 'refreshing'. Republicans there can lose no more than two votes from their 52-member majority.
Whatever Trump's struggles, the poll shows clear risks of Democrats' opposition to Trump.
Trump's behavior comes in for some criticism even in his own camp.
The current poll, which surveyed 1,001 USA adults, was conducted July 8-12.
In the "surge" counties, Trump beat Hillary Clinton by a combined 65 percent-to-29 percent margin, and in the "flip" counties Trump's margin was 58 percent to 39 percent.
