WASHINGTON POST - Feb 14 - Politics or good sex question is one of over 5,000 that OkCupid poses to members to help narrow down their search for a partner. Over 4.5M people have opted to answer it since it was added about a year ago, and the way they respond has a lot to do with their generation. 17% of Baby Boomers (born before 1965) and 15% of Gen X-ers (born between 1965 and 1980) choosing politics over sex. But among Millennials, which the company defines as born between 1981 and 1997, 38% choose politics over sex, and for Generation Z, born in 1998 or later, it's nearly half and half, with 48% preferring political rather than sexual compatibility. The generational differences are not surprising to Paul Taylor, author of "The Next America: Boomers, Millennials, and the Looming Generational Showdown," who noted that politics have become much more personal and polarizing in recent decades. In 1960,~5% of Americans expressed a negative reaction to the idea of their child marrying someone outside their political party, he noted, whereas in 2010, ~40% did.
