How do people with different music preferences vote?

[Alben Barkley]

You’re probably broadly right, although “pop” is so broad and, uh, popular I’d imagine its fans have pretty diverse views too. Rock would have at one time had a solidly Democratic/left-leaning fanbase, but sadly it’s largely now seen as “safe” and “boomer” music, no longer as transgressive or cutting edge as it once was. Following the same trajectory as jazz pretty much. It’s currently in the stage of “music your parents listened to,” which is where jazz was when rock was hip, and after jazz itself was transgressive and cutting edge. Perhaps when the boomers die off rock will, like jazz now, have a niche but hip and left-leaning base of NPR listeners.
