First, it will take something more serious than alleged campaign-finance violations to overturn an election through impeachment. The two-thirds majority vote required for conviction in the Senate was designed to be a stumbling block to factions and passions, and it saved Clinton during the Lewinsky scandal.

It’s also worth remembering that Clinton’s misconduct occurred in the White House, while the Trump allegations involve events before he became president.

Second, Trump can cure the injustice stemming from the one-sided probe by declassifying documents the Justice Department is hiding from Congress and the public. Everything he wants Sessions to release could become public with the president’s signature.

I have called this power Trump’s ace in the hole because revealing the dirty details of how insiders tried to steal the election could bolster his support. His refusal to play that card is bewildering.
