Iowa is an anomoly. Yes on the presidential is quite blue, voting twice for the Marxist and usually in the Democrat column for president.
But statewide, it does have A GOP governor and state legislature. The people there may be dovish on foreign policy, but they are also frugal on spending. I would have to imagine Iowa is a basically well managed state that keeps it spending in line and manages its finances responsibily.
Free Money NOT to grow crops has its benefits. Iowa has been in the cookie jar for many years.
