Already Republicans are planning the same for Mrs Clinton, with talk of congressional investigations and even impeachment. This is obviously presumptuous: if nothing else, the emails may turn out to be entirely benign. Mrs Clinton has confidently asked for the FBI to release everything it has on her. But if Republicans do control the House, maybe even the Senate, then she is going to have a very rough time. One does not have to be a supporter to see tragedy in this. Washington is deadlocked as it is. Growth in the US economy is slow. The Middle East is in turmoil and Russia is accused of starting another Cold War. The world needs strength and leadership in the White House.
