Trump's overall approval rating was nearly the same among Arizona's likely and registered voters. Out of the registered voters who responded to the poll, 42 percent approved of Trump's presidential performance while 43 percent of those who indicated they were likely to vote approved of the job Trump is doing.

Half of Wisconsin's likely voters would vote for Biden if the election were held today. In the poll, the Biden-Harris ticket received 50 percent while the Trump-Pence ticket received 42 percent, a difference of 8 percentage points.

Biden's lead among registered voters in Wisconsin remained the same with 49 percent giving the nod to Biden and Harris. Trump and Pence garnered 41 points among the same demographic, giving the Democrats another 8 point lead.

Wednesday's data indicated a tighter race in North Carolina with only 4 percentage points separating the Republican and Democratic tickets.

Biden and Harris held the support of 50 percent of North Carolina's likely voters with Trump and Pence receiving 46 percent. Registered voters gave the Democrats 49 percent of their support while handing Trump and Pence 45 percent of their support. Although the numbers between registered and likely voters shifted slightly according to party, the span between the two remained at 4 points.

Only 1 percentage point separates those who participated in the poll on their opinion concerning Trump's performance as president. Both registered and likely voters approved of Trump's performance by 49 percent while 50 percent disapproved.

Newsweek reached out to both the Trump and Biden campaigns for comment.

Polls in all three states carried a margin of error of plus or minus 3.5 percentage points.

Both campaigns have placed a focus on Wisconsin, particularly the city of Kenosha where protests erupted after the police shooting of Jacob Blake. Biden is expected to visit Kenosha on Thursday.

Trump visited Kenosha on Tuesday to survey the damage left after civil unrest. Some lawmakers had encouraged Trump to delay his visit.

"Some people thought it would be a good thing for me to come, a bad thing," Trump said during his visit. "I just wanted to come. I really came today to thank law enforcement."
