President Trump swept to the presidency by scoring upset victories in Michigan, Pennsylvania and Wisconsin. Now, his approval ratings in all three states sit at around 35% according to a new NBC/Marist survey. The polls were conducted after the events in Charlottesville.

In each of the three states, voters were twice as likely to say Trump has embarrassed them rather than made them proud since taking office.

Just last month, CNN found approval ratings of 43 (WI) / 43 (PA) / 42 (MI) in the three states.

In November's election, Trump scored 48 (WI) / 49 (PA) / 48 (MI)

Why it matters: Trump's economic message helped him outperform traditional Republican candidates in these states, and without them he wouldn't be president.
