I suspect that the more that Trump’s opponents, or the media, attack Trump on this front — for having bad taste, for being boorish, for his lack of intelligence and refinement — the more these voters are, or shall I say were, inclined to embrace him.
You might think people who are drawn to gold-plated seat belts would be attracted by the glitter and splendor of a concert hall or opera house. After all, the “elitist” accoutrements of much high culture have a glitzy razzle-dazzle (ballet costumes! red velvet seats! traditional opera sets!) in common with the Trumpian aesthetic.
