Support for President Trump among white college graduates is generally trending down across the industrial Midwest states formerly known as the "blue wall." According to the NBC News Exit Poll of early and Election Day voters, Trump is winning the support of 43 percent of college-educated white voters in Michigan, which is down from 51 percent in 2016. The pattern is similar in Pennsylvania, though far less pronounced in Wisconsin.    

The exit poll indicates that support for Trump has also dropped in this region among white voters who did not graduate college, with the notable exception of Pennsylvania. In the Keystone State, Trump is maintaining his strong support among working-class white voters, carrying nearly two-thirds of their vote this year. In Michigan and Wisconsin, however, Trump’s vote share among white voters who did not graduate college is down by about 5 to 8 percentage points.
