How much does sex have to do with politics? A lot, apparently. According to a longitudinal study of men begun with a group of 268 Harvard undergrads in 1938, the aging liberal male has a great deal more sex than the aging conservative male.

"With regards to income, there was no noticeable difference in maximum income earned by men with IQs in the 110-115 range vs. men with IQs above 150.  With regards to sex lives, one of the most fascinating discoveries is that aging liberals have way more sex.  Political ideology had no bearing on overall life satisfaction, but the most conservative men on average shut down their sex lives around age 68, while the most liberal men had healthy sex lives well into their 80s.  Vaillant writes, 'I have consulted urologists about this, they have no idea why it might be so.'"
