“The standard Sanford has set for other politicians over the years has been fairly high. A member of the House of Representatives during the heyday of the Clinton-Lewinsky affair, he was often a harsh critic of the president for his marital misconduct.
“This is ‘very damaging stuff,’ Sanford declared at one point, when details of Clinton’s conduct became known. ‘I think it would be much better for the country and for him personally (to resign)… I come from the business side,’ he said. ‘If you had a chairman or president in the business world facing these allegations, he’d be gone.’ ” 
” ‘The issue of lying is probably the biggest harm, if you will, to the system of Democratic government, representatives government, because it undermines trust,’ [Sanford] told CNN. ‘And if you undermine trust in our system, you undermine everything.’ ”
