The rich actually tend to be way more consistently conservative on social issues, at least IIRC. Poorer people tend to be less politically engaged and so have some heterodox collections of opinions - e.g., being harshly anti-immigrant while supporting legal abortion.

I think this partly explains why GOP party elites (e.g. SCOTUS) thought that outlawing abortion wouldn’t generate much backlash, when in reality few people are 100% right (or left) on any given issue.
