I think there is likely a stronger correlation to wealth rather than politics. When people have it really good, they get sort of mentally spoiled by getting everything their way. So, when they encounter something that is not to their liking, the reaction is stronger because they've been able to successfully avoid it for longer. The disgusting thing threatens their on-a-higher-level equilibria and therefore is a stronger threat to them than it would be to a lower class person who has to encounter it more often. Less well-off people who have to get their hands dirty more often build up mental callouses to the grosser aspects of life, like handling compost, cleaning wounds, etc.
