A study suggests there may be a tie here. A gene that links certain behaviors and that includeds being a liberal?!?!? Interesting and not surprising if true. http://www.tgdaily.com/general-sciences-features/52838-researchers-identify-wild-orgy-gene MÃ©nage Ã trois? Wild orgies? One night stands? Who says science can't be sexy? Certainly not Binghamton University researchers, who are hard at work uncovering the sultry secrets behind human sexual behavior. The team - led by Dr. Justin Garcia - recently identified a dopamine receptor gene known as DRD4 that is purportedly linked to chronic infidelity and "uncommitted" one-night stands And wouldn't you know it? The very same gene has already been linked to alcoholism, gambling addiction and a predilection for really bad horror movies. Oddly enough, another study claimed the mysterious gene was responsible for political liberalism, along with "openness" to new social situations. "What we found was that individuals with a certain variant of the DRD4 gene were more likely to have a history of uncommitted sex, including one-night stands and acts of infidelity," Garcia confirmed.
