In the state of Arizona, Trump trailed the former vice president by six percentage points. The Democrat was seven points ahead in Florida and six points ahead in Michigan and Wisconsin.
In Pennsylvania, Biden polled at 50 percent and Trump at 42 percent. In North Carolina, 47 percent of respondents expressed support for Biden and 46 percent for Trump.
Across the six states, Biden led Trump by six percentage points. Nationwide, the former vice president polled at 51 percent, putting him 10 points ahead of Trump's 41 percent.
In general, voters in the six swing states do not seem to approve of Trump's performance in the White House.
Forty-three percent of those polled said that they approve of the way the president has handled the coronavirus pandemic, while 57 percent disagreed.
On the issue of economy, 48 percent approved of Trump's performance in office and 52 percent disapproved.
Forty-five percent of respondents said that they approve of the job the president has done on immigration, while 55 percent disagreed.
"The negative views on Trump's job performance come as he has played down the roiling health and economic crises caused by spikes in coronavirus case across the South and West. The U.S. seven-day average of new infections topped 60,000 for the first time on Monday," CNBC noted.
"The poll underscores dissatisfaction with how Trump is managing his presidency -- even in six states that he won in 2016. The battlegrounds, which include coronavirus hot spots Arizona and Florida, will likely once again determine who wins the White House this year."
Fifty-four percent of respondents said that Biden would handle the COVID-19 pandemic better than Trump. Fifty-five percent said Biden and his fellow Democrats would do a better job of "making health care more affordable," while 53 percent said that the former vice president and his allies would put the middle class first.
Recent polling suggests that Biden has expanded his nationwide lead. The latest Quinnipiac University survey put Trump 15 percentage points behind the Democrat, establishing that the president has lost ground among Republicans and independents.
The poll also showed that Trump's approval rating has dropped six percentage points since June, with 60 percent of respondents saying that they disapprove of his performance in the White House.
As The Inquisitr reported, the latest Rasmussen Reports survey was the most favorable recent poll for the commander-in-chief, showing Biden with a three-point nationwide advantage.
