I don't think you can ignore the "self-flagellation" component of Puritanism ie "if I vote for what I Really Want... I might experience pleasure..
Sample re (IIRC) a Sinclair Lewis novel, in which is decribed an autocrat with his family at dinner. The kid doesn't want to eat _x_ and the father wants him to. Finally wife says, "oh let him eat what he wants..!" Father explodes, "IN MY ENTIRE LIFE I'VE NEVER DONE A SINGLE THING I WANTED TO DO.."
Yes exaggerated, yet - have heard such a rationale (once stripped of self-serving euphemism) in those 'explaining'.. how it was that, serially they chose:
abusive spouses. As below so above (to paraphrase).
Funny species.
