President Donald Trump is losing his job approval ratings in three crucial US states that put him at helm in the White House in the wake of a terrorist attack during a demo against white supremacy in Charlottesville, Virginia, a new poll shows.

According to the NBC News/Marist polls released Sunday, the president was becoming less popular in the key states of Michigan, Pennsylvania and Wisconsin.

In the 2016 presidential election, the three states gave the Republican nominee his margin of victory by providing him with 46 electoral votes to become the president despite losing the popular vote to Democratic nominee Hillary Clinton by 2.9 million votes.

The president’s approval is currently below 40 percent in all the three states: 36 percent in Michigan, 35 percent in Pennsylvania and 34 percent in Wisconsin, according to the poll.

The New York billionaire’s disapproval ratings also exceed 50 percent.

Trump’s performance as president has been embarrassing to nearly two-thirds of those polled in each state.

The president has been under fire due to his failure to immediately condemn the recent tragedy in Charlotesville, in which a driver plowed into demonstrators protesting against white supremacists and killed a young woman and injuring nearly 20 others.

Instead, he has blamed both sides for the clashes that took place on August 13.

Heather Heyer, 32, was killed and some 20 others were injured.

A 20-year-old Nazi sympathizer, identified as James Alex Fields Jr, was said to have been behind the wheel.

According to GOP strategist Ana Navarro, the president has failed grab the opportunity to unite the already divided nation in the wake of the horrendous attack.
