There is a very good reason why Trump did not go to Minnesota and Michigan. They are still blue states, which means that a visit by Trump would likely bring out otherwise unmotivated Democrats to the polls. You don’t see Hillary campaign in Florida “s panhandle? Why? Because you don’t want a higher turnout in an area that will vote 2:1 against you. We want higher turnout in AZ , Tennessee, Missouri, etc, but lower turnout in Michigan and Minnesota.
OP Here,
Thanks for all the replies. I also just found out Michigan isn’t an early voting state.
