Conservative minorities don't shift to the right, they're far right and temporarily move left whenever the Republicans get a little too on-the-nose. A Democrat in office means they won't be exposed to that rhetoric for a few years so the "bloc" will swing back to their baseline for a cycle or two. I'm trying to think of a visual analogy that isn't a double pendulum.

I feel like the "voting against their best interests" trope exists because people don't realize that conservative minorities vote as far right as the GOP will let them. Because they're conservative.
