I have been following that one. The blue laws were really strict when I was a kid... in the nearest "big" town to me, a town of 8000 at the time, there was virtually nothing open on sunday, except for one little store in a house where one could get aspirin or soda pop and such if one was willing to pay 3 times the normal price for the convenience.
Alcohol sales were majorly verboten. Gasoline was not even available. The sunday paper was available from a guy with MS in the shelter of an entry way to a closed downtown store.
There is a movement to go back to that, which as the article stated, nearly passed, it was close. It has more to do with religion than nostalgia, as there are a lot of self-righteous pious norwegians and germans there. They have rallied in their hatred of the Sioux pipeline protest, ball caps clearly proclaim which team they are on. Being redneck enough to glow in the dark is an aspiration for them; the pipeline has galvanized them into lockstep against the tribal interests.
Heidi Heitkamp, the democratic senator from there, has probably reached the biological limits of what can be called a democrat. She is an NRA darling and almost got a cabinet post. If she had, a republican would have been appointed to fill her seat, which became unnecessary since the republicans eked out their slim majority without the need to eliminate her. I think her strategy on this issue is to not be in North Dakota on sunday, or most any other day.
