Mapping Trump's Drop in Approval Rating by State

From January to September, Trump's approval ratings have dropped nationally. But more, they have dropped in every single state. Using data from this week's Morning Consult, which interviewed almost half a million registered voters, the state-level drop for Trump ranges from 11% (Louisiana) to 31% (Illinois). The map below was generated from first taking his approval ratings minus his disapproval ratings for January and September, then subtracting the January rating from September. This is shown in the first map.

In contrast, the second map shows that there are many states where Trump's approval is still above water. This ranges from Hawaii at a low (-33%) to Wyoming (-26%). Twenty-seven states have Trump underwater, and 23 above. Both of these maps were created using Quantum GIS.
