Yeah, except not. This is a blinkered, false narrative not supported factually.
Fact: the more affluent across income brackets vote Republican, and even in ‘blue’ domains. That the majority in a metro area or state vote Democrat does not make those voters more affluent by association. The more affluent even in those areas are more likely to vote Repub in higher percentages.
Hillary won the “poor” individual vote, while Trump still won less affluent *regions* and the affluent vote. This is hardly a secret phenomena and reflect longstanding voting patterns.
But even income brackets are false indicators. A family making $50k in AL is, in practicality, more affluent than one pulling $50k in CA...which is, incidentally, why CA has the highest poverty rate in the US, in practical application (Supplemental Poverty Measure).
Having fewer voters with degrees does not mean they are “uneducated” and working low wage, low skill jobs. Like slinging PBRs for a living, for example. In fact, that across the spectrum R voters have higher incomes in both practical and absolute terms and are less likely to be unemployed and underemployed and consume less subsidy, these voters are exactly the kind of Americans who keep this economy moving, whether degreed or not. They are certainly not, as you imply, unintelligent. They are disproportionately *not* poor.
Lastly, red states absolutely dominate the rankings of most fiscally sound states while blue ones command the least solvent rankings.
Now fetch me another beer, you educated barmaid.
