I did not mean to capitalize "political". So, I was reading about the connection between sensitivity to disgust and which political side a person supports. People who display stronger brain activity when shown a gross picture are more likely to be conservative, even when controlling for other personality traits. I was reading on what other influences and connections disgust has with a person's health status and personality. I saw this in an NY Times article: "Daniel Fessler, an anthropologist at the Center for Behavior, Evolution and Culture at the University of California, Los Angeles, investigated with his colleagues why pregnant women were more sensitive to disgust. What they found was that as progesterone levels went up, so did sensitivity to disgust." "In very recent work, Dr. Fessler said, the researchers found that even in women who weren’t pregnant and were not suffering nausea, disgust increased with the levels of progesterone." Here's the original study. The article is from 2012; here is the "very recent work" he references.
