Food preservation lines up very well with conservative and libertarian plans. I even know if your number of Democrats that enjoy preserving food. Dehydrating, canning, pickling or all cheap and easy. The more extremes in conservative and libertarian also seemed to like freeze drying. I have to admit I kind of like freeze drying myself but the machine is so freaking expensive and then it consumes so much power, you can literally buy commercially freeze dried food cheaper than you can make it yourself and that does not get better at any reasonable home scale.
