Ezra Klein: “Impeachment acts as a form of public disgrace. To be one of only four impeached presidents in American history, even if you are not convicted by the Senate, is to know an asterisk will be forever attached to your presidency, your offenses prominently recorded. It’s a humiliation for you and a warning to your successors.”
“That’s one way in which impeachment acts as a deterrent. It’s a statement that a particular action falls outside the boundaries of normal American politics, that the behavior violated the public trust in a historic fashion.”
“This is not as strong a punishment as removal from office, of course. But it’s a stronger punishment than some Democrats issuing critical press releases before moving onto other issues. And it may yet lead to removal from office.”
