I'd point out that just because blue-collar folks may not mean to deceive others and may engage in "plain" speech, doesn't mean they're not massively self-deceived. For example, many pretend they're not sexist or racist.
I believe Maryland as a whole is Democratic, but the rural parts of that state, as in most states, vote Republican. It's the big cities and urban areas versus the rural parts.
I'm aware you like to bring all of these subjects back to your theory of underlying duality. But sometimes this might across as evasive, no? I suppose you don't believe politics emerges from certain natural dynamics, so that politics takes on a life of its own and needs to be understood in terms of a higher-level vocabulary.
Your account seems pretty reductive, which would be fine as long as you could show in detail how the higher-level dualities (such as liberal vs conservative) reduce to the lower ones. I mean, I too have a reductive account of politics (links below), but I reduce the political largely to the biological and the sociological, not straight to metaphysical categories such as the absolute, transcendence, and the infinite. It’s quite a leap you frequently want to make.
