The survey results showed a marked difference in the general opinion of the three states since the November election, when Trump became the first GOP candidate to take the three states since the 1980s.
Trump registered just 35 percent support in the poll taken August 8, and released on the same day Heather Heyer was mowed down in Charlottesville, Va. during an "alt-rally" that the president has been widely criticized as being too tepid in his condemnation of.
Wisconsin: 56 percent disapprove, including 42 percent strongly, compared to 34 percent approval (17 percent strongly).
Asked if Trump's conduct since taking office made them proud or embarrassed, 64 percent of voters in MI and Wisconsin and 63 percent in Pennsylvania say they have been embarrassed, according to NBC News/Marist polls. In all three states more than 60 percent of voters said Trump's conduct as president embarrassed them, compared to 25 percent who say it has made them proud.
One of the few bright spots in the poll for Trump lies in his handling of the economy, where 44 percent of Americans believe the economy has strengthened based on his decisions, compared to 46 percent who feel that it has weakened under his guardianship.
Trump's performance as president has been embarrassing to almost two-thirds of those polled in each state. Sixty-three percent in Pennsylvania said the same thing.

On Tuesday, Tim Anderson hit Alex Wood's first pitch for a home run. "I don't want to be the bad pitcher". Two of the home runs were leadoff shots. "It's a credit to the guys in the clubhouse", Dave Roberts said.
This latest poll contrasts slightly with a national poll conducted by Quinnipiac University that showed an uptick in Trump's approval rating.
NBC surveyed 795 voters in MI, 773 in Pennsylvania, and 801 voters in Wisconsin from August 13 through August 17. Some 60% of voters in all three states said they believe the US' role on the worldwide stage has been weakened by Trump. The margin is 45-to-38 percent in Pennsylvania and 41-to-41% in Wisconsin.
In Pennsylvania, Democrats hold a 10-point advantage on congressional preference, 47 percent to 37 percent.
Some polling analysts cautioned that since the poll was conducted directly in the aftermath of Trump's initial failure to condemn a violent white supremacist gathering in Charlottesville, Virginia on August 12, it could have exacerbated his unpopularity.
Trump on Saturday initially said "many sides" were to blame for the violence.
