I can see Maine trending back that way.
Michigan was a fluke though
Possibly, but the margin for error is slipping because Detroit is shrinking. So Detroit declining might just mean in a future cycle a Democratic candidate gets the same level of support in raw numbers of Detroit, despite superior turnout by percentage and thus loses because there are simply fewer voters voting in the city. On the other hand they might be in Atlanta voting.
Alternatively, I wouldn’t be particularly surprised with a major resurgence of Detroit pushing Michigan back left. We might see a bump back to a lean dem state in 2020, with a short-medium term trend making it an R leaning swing state, and longer term it being D again.
