Why so few women in infidelity club?

(Politico) - When South Carolina Gov. Mark Sanford admitted to an extramarital affair on Wednesday, he presented an all-too-familiar tableau: the pained expressions, contrite words and teary gaze of a male politician confessing sexual indiscretion. Coming close on the heels of a similar admission from Sen. John Ensign (R-Nev.), it is clear that sex scandals will always be with us.

But after two of the same dramas within two weeks, it’s fair to ask: Does the casting ever change? Are female politicians really that much more faithful — or are they just not getting caught?

“We don’t have any data that women are more honest and pure when it comes to this sort of stuff,” said Debbie Walsh, director of the Center for American Women and Politics at Rutgers University. “But we certainly have evidence that we just don’t see women falling prey to [public disclosure of affairs] in the same way that men have been.”
