Democrats, who generally have a more liberal take on sexual matters, were least likely to use an adultery dating service, while members of the conservative Libertarian party had the greatest tendency to do so. This is according to an analysis of leaked user data from Ashley Madison, a website that connects married people who want to cheat on their partner. Greens and voters not registered to any party used the site more than Democrats, whereas Republicans used it more still, but less than Libertarians. The findings by Kodi Arfer of the University of California Los Angeles and Jason Jones of Stony Brook University, both in the US, are presented in Springer’s journal Archives of Sexual Behavior.
