Hope I got that right guys ~ my only connections to Iowa are in the SE where you'all think they speak with a Souvrn' accent.
Look at the county map. Eastern Iowa voted DEM. The rest was Republican. 62 Republican counties and 36 Dem counties. Farmers are notorious for voting AGAINST their own self interest. At least, that has been the case in my lifetime.
Iowa is no longer anything like the Iowa it was (and that outsiders think it still is). The "family farm" is now an agribusiness that is heavily subsidized by FedGov-- families may own them, but aside from a few remaining small farms (often dairy operations in the more rolling areas near waterways), they are fewer, larger and are definitely big business. The small towns that depended on having a lot of relatively close small family farms (each with many more children/hands in the old days) continue to die and become either bedroom communities, a collection of meth lab/Section 8 housed going to seed or semi-ghost towns with maybe an agriculture-related business or two, but that is about all... and those related businesses naturally depend on the farmers, so they are indirectly dependent on the government.
Except for the ag-related industries (the various Deere works and their vendors, etc), there isn't much left here for big employers other than insurance outfits in Des Moines and the local/county/state/federal government. Nowadays, many smaller communities offer only public sector jobs, jobs working for contractors who build/maintain government infrastructure (roads, schools, buildings, etc) or at the branch of a local bank. IOW, most jobs here actually revolve in some way around the government teat, and that makes it like a perpetual motion machine, in that it really doesn't - more factually, CAN'T - actually work without power from the outside.
I'm a lifelong, fourth-generation Iowan, and the Iowa I grew up in has been dead for around 30-odd years, but it took me a while to see that it was gone. Western Iowa sucks less than Eastern Iowa as a general thing, if only because Western Iowans are less likely to aspire towards being Chicago or Madison.
