They're counting on the cold to keep the idiots away. Or so thought Wally Kowalski. . .
I would think those who live out in rural areas of those states would be decently well prepared. Assuming they are used to the weather and plan accordingly. That and the winter weather serves as a sort of protection for many months out of the year. Those from warmer climates would suffer in the cold. Much like the Starks of Winterfell and dealing with the southern armies.
Planning is the key to surviving Winter. Find some large game just prior to the onset, put up some fresh veggies in jars, maybe leave your canned goods for then, and amass a large supply of firewood that's protected from the elements (tarps, plastic sheeting, wood sheds).
One of the hardest tasks in Winter is keeping yourself and your clothing clean. Dirty clothing is not only unsanitary, but the filth causes the material to wear out quicker. Clothes need to remain as clean and in good repair as possible to last. Of course, good hygiene prevents illness. You'll need to plan on having hot water for those things and a large tub to bathe and do laundry in. I've taken a shower once in the mountains of W. Virginia in Winter when the electricity went out the night before. OMFG! That was the fasted shower of my life!
