That's the advice Yglesias has for politicians embroiled in scandal:
When a reasonably popular public official is hit with a scandal of a personal nature, the natural immediate first reaction of his same-party colleagues is to want to get rid of him. After all, no reason this guy should be a millstone around all of our necks. That leads to an initial torrent of criticism from friendly-ish sources and a wave of pressure to resign. But if you resist that first wave, apologizing for your conduct but refusing to apologize for your years of public service and highlighting the pernicious special interests who’d love to see you brought low, you basically flip the dynamic. Now you’re definitely going to be a millstone around everyone’s necks so the question becomes how heavy a stone?
Suddenly all your same-party colleagues have an incentive to defend you and to attack your enemies.
He uses Bill Clinton as an example of someone who refused to resign and Elliot Spitzer as someone who folded under pressure.
