In the early stages of the Monica Lewinsky scandal, there was a period when one of the questions raised by the whole affair had to do with monogamy. Around that time, Roy Romer, the Governor of Colorado and Chair of the Democratic Party, admitted that for 16 years he'd had a relationship with an aide that his wife and family knew about. We hear tape from Romer's remarkable press conference in which he urged people to talk more realistically about how they really live in their marriages, instead of pretending they are monogamous.

It's a social revolt, she says, like wildcat strikes. (8 minutes)
