“Better for the country” doesn’t have to be “nuanced.” “The best thing for America is god, guns, and capitalism” is not nuanced. It is, ultimately, an expression of values based on a belief about what will enhance national prosperity.
(I could recount “real discussions” with folks in northern Virginia growing up, where they express sneering contempt for the folks in the “rest of Virginia.” I don’t think that’s relevant. Obviously race and class play a role in political disputes in the US. That doesn’t excuse making assumptions about why entire groups of people vote the way they do.)
