It makes no sense at all.
MN/IA/WI aren't states with industrial bases in secular decline like OH/MI/PA.
They have a much bigger agricultural presence.
Their residents tend to be better-educated and have lower rates of poverty.
They are much more racially homogeneous than OH/MI/PA with a disproportionate number of white people of German/Norwegian/Dutch ancestry.
Basically, they're some of the least hospitable states to Donald Trump.
Basically.
The GOP "establishment" in Wisconsin (Iowa to some degree) was basically the only organization in the country to derail the Trump train. The "establishment" will back him eventually (somewhat grudgingly) and he has a lot of appeal with 'Reagan' democrats.
Can he win? yes, but it's different than the eastern rust belt.
