Can't say I cared much either, but Spencer's text was such a blatant piece of propaganda that I felt the appropriate response was ridicule. He doesn't really "describe" an "electorate bifurcated along class lines, etc." but rather supposes it--allegedly on the basis of Piketty's authoritative masterpiece of a report--and, of course, that supposition happily affirms his pre-existing commitment to what can adequately be summarized as Trotskyism. It's a joke.
On the other hand, one can't help but wonder if this isn't an early outrider in the genre of crafting a narrative to be deployed in the event the Democrats lose the 2020 election. In this instance, the author would be proposing that said narrative take the form that the explanation for the loss ought to be that the Democratic nominee was insufficiently Trotskyist. Again, 'tis silly stuff.
"The Republican Party has earned a reputation as the anti-science, anti-fact party"
One third of the way in to Mr. Spencer's first sentence--and we know immediately we're reading a piece of the utmost sobriety...
Spencer's piece is essentially an argument from authority--in this case, the authority of "data", indeed "hard data", and even (breathtakingly) "mounds of data"; helpfully compiled for us by that superstar of contemporary data-driven social "science", Thomas Piketty. Though it's wisely, if not perhaps widely, understood that contemporary data-driven social "science" is an enterprise of unimpressive stature, Spencer's affection for it is--shall we say--affecting.
So, Spencer’s point--on the authority of Piketty’s "mounds of data"--is that, if the Democrats will only nominate a candidate of Trotskyite persuasion, then he/she/zhe will obtain a sweeping victory. Speaking as one whose socialism tends to the "false consciousness" Straßerite variety, I hope they’ll do so. Let’s conduct the experiment and see if Piketty’s right...
I shan't belabor further my annoyance with Spencer's drivel, except to address en passant the only curiosity that emerged as I read it--namely, the strange phenomenon of apparently bona fide and old-time socialism in the state of Oklahoma. Well, what can one say--except that the denizens of Oklahoma haven't exactly earned a reputation for wisdom of a political or any other kind, now have they?
