The economy is still messed up, Biden will win it
The economy is messed up in Michigan because Whitmer closed the state. South Dakota is doing fine. It really comes down to who voters blame. In my experience (PA has similar harsh shutdown rules), old people tend to blame Trump more, which is perhaps understandable as they are the most at risk and favor lockdowns more. Younger and middle aged people are angry at Wolf for crippling the economy and their social lives.
Kirsti Noem is a sociopathic hag who refused unemployment benefits for her home state.
I suspect Macomb will go for Biden narrowly. In general, I expect the suburban WWC Obama/Trump areas (Macomb or Staten Island) to swing toward the Dems more than the truly rural or small city WWC Obama/Trump areas.
I don't like that you are calling Kristi Noem a "sociopathic hag". I think you can do much better than that.
