Exactly the same for relatives in MN! Very conservative except for how they vote.
I live in MN so I know you are right. They actually remind me of union construction workers I met over a 40 year period.
You could talk to them all day about hunting, fishing, beer,
general guy stuff etc. But if you mention politics they get the glassy eye look and the demons take over. I never talk politics with union people or farmers unless I want to get them really mad at me when I tell them the truth. To them, the truth hurts.
