You come at the Trump, you best not miss
The third presidential impeachment in US history has now reached the Senate. Like the first two, this one is almost certainly going to lead to presidential acquittal. An old saying given definitive expression by Ralph Waldo Emerson (and recently adapted by The Wire) warns that you should 'never strike a king unless you are sure that you shall kill him'. Congress may not be risking royal reprisal here, but it is teaching all Americans — including all future presidents — a fateful lesson in institutional impotence. After this, who is ever again going to take the threat of impeachment seriously? Congress has called its own bluff.
