Presumptive US Republican presidential nominee Donald Trump is “unfavored” by the majority of American voters, a new poll has found.

The ABC News/Washington Post survey, released Wednesday, showed that Trump is facing a growing popularity issue as 7 in 10 Americans have unfavorable views of him, a 10-point rise since last month.

The new figure falls only one point shorter than Trump’s record unfavorability in the poll, which was recorded in May of last year.

Since then his unpopularity ratings hovered around 60 percent and started to decrease towards the end of the primary race.

Only 29 percent of the participants said they approved of Trump, reversing a boost he received after securing the nomination last month. Back then he had a 37-60 percent favorable-unfavorable rating.

On the Democratic side, presumptive nominee Hillary Clinton suffered the same problem more or less.

She was viewed unfavorably by 55 percent of Americans, her worst score so far. However, she had a stronger favorability rating than the New York businessman, trumping the billionaire with nearly 43 percent support.

Trump’s high unfavorability rating is attributed to his comments regarding the deadly mass shooting in Orlando, Florida that killed nearly 50 people on Sunday.

Having made a reputation for his Islamophobic remarks, Trump took the opportunity to spew more explosive and forceful political rhetoric against Muslims.

"The current politically correct response cripples our ability to talk and to think and act clearly," he told his supporters at Saint Anselm College in New Hampshire. “If we don't get tough, and if we don't get smart, and fast, we're not going to have our country anymore. There will be nothing, absolutely nothing, left.”

Clinton, on contrast, called for unity and outreach to Muslims in the wake of the attacks while urging stricter gun-control measures.

According to an NBC News/SurveyMonkey released Tuesday, Clinton’s lead over Trump has broadened to 7 points nationally - 49 to 42 percent - among registered voters.
