I've always joked that Nebraska is full of tax and spend Republicans. Basically people vote R because that's what their parents did, and that's what they think they should do, and of course the dems are evil socialists... but policy-wise, the state seems much more left-leaning than the other states around it in my experience. Well-funded schools, tons of public work projects going on, registering a car costs roughly a billion dollars, etc...
All that said, I'm sure plenty there will hate him for this, for the exact reasons he mentioned.
