The following is simply raw speculation on my part.  I’ll be interested in your comments.

There are musical styles that align themselves with left- and right-wing politics, though none of these, with the possible exception of one, has 100% of its audience–more on this below.

Here are a few musical genre, where they seem to be pro- or anti-Trump. and why:

Classical.  Largely but not exclusively anti-Trump.  Classical appeals to the mind and the emotions that surround the perception of beauty.  There are exceptions, in that there are plenty of billionaires and weirdo intellectuals, e.g., the “objectivists” of Ayn Rand fame many of whom adore classical music.

Country.  Pro-Trump.  Most of it appeals to people whose most nuanced thinking is getting drunk and laid.  Preferably at the same time.

HipHop: Pro-Trump.  The opposite of classical, this is music that appeals to the genitalia as opposed to the mind.

Rock.  Mixed bag.  Heavy metal probably favors Trump; prog-rock fans of bands like Yes and Pink Floyd have too much going on in their minds and hearts to be Trump supporters.

Folk: Mostly anti-Trump.  Pete Seeger and Bob Dylan fans aren’t big fans of stupidity and fascism.  I’m sure there are exceptions.

Reggae: Distinctly anti-Trump.  Black folks’ songs of love, peace, weed, and escape from enslavement aren’t going to resonate with the hate of the White supremacists.

The Grateful Dead.  I’ll leave you with this.  If you can find me a single Dead Head Trumper, I’ll be astounded.  Now, I know that essentially no one sits on the fence about the Dead, but there is essentially zero intersection of Dead Heads and those who favor war, corruption, hate, greed, and ignorance.

Religious statements fly in the teeth of science, but even the most ardent believers in God are going to have trouble with the meme here.

The reason men have nipples is that their gender isn’t assigned until about six weeks after conception, when chromosomes trigger hormonal changes that differentiate male and female anatomy.

Did God Assign Your Gender?

It’s possible that Americans are so angry that the Trump administration has ruined their country and its democracy that paid advertising for Republican candidates is having no effect on them.

We can only hope.

Are Americans Fed Up with Trumpism?
