Trump Would Jail Clinton? There's a Name for That

Donald Trump’s threat in Sunday night’s presidential debate to appoint a special prosecutor to go after Hillary Clinton’s use of a private e-mail server is legally empty -- but it’s genuinely dangerous nevertheless. Federal regulations give the appointment power to the attorney general, not the president, precisely to protect us against a president who uses the special prosecutor as a political tool.

What separates functioning democracies from weak or failed ones is that political parties alternate in power without jailing the opponents they beat in elections. That sometimes means giving a pass to potentially criminal conduct, but that’s a worthwhile sacrifice for making republican government work.
