Today's Useful Data: Rustbelt Voters Bail Out on Trump

As Trump's approval ratings continue to fall everywhere, his tenuous hold on the key Rustbelt states that handed him the Presidency is slipping away. Here's the key paragraph from a new Morning Consult analysis of data from 472,000 (!) interviews conducted since Trump's inauguration:

A majority of voters in 25 states and the District of Columbia said they disapproved of the president’s job performance in September, including those residing in Upper Midwest states with large Electoral College hauls that were critical to Trump’s victory over 2016 Democratic presidential nominee Hillary Clinton — and some of which are home to some of the most vulnerable Senate Democrats of the 2018 election cycle. Fifty-five percent of respondents in Michigan said they disapproved of Trump, as did 53 percent in Wisconsin and Iowa and 51 percent in Pennsylvania.
