When Newt Gingrich cheated on his wife, that was apparently perfectly acceptable to his peers.
When Bill Clinton cheated on his wife, he was nearly hounded out of office by Republicans led by Gingrich, who orated passionately about the moral rectitude apporpriate to elected office, at the same time he was having an affair. Not only is this the basest form of hypocrisy, but intellectually dishonest because the issue of Clinton's infidelity was presented to the American public in a way that suggested Clinton should be held to a different, higher standard than Gingrich and other adulterers in elected office.
