Senate Republicans are completing one of the most flagrant cover-ups in American political history, but House Democrats gave them plenty of excuses for their dereliction of duty.

For years, the Democrats cried wolf by threatening impeachment against President Trump when no impeachable offenses were evident. Then, when finally handed a set of circumstances that manifestly made impeachment a reasonable discussion, the Democrats repeatedly made it look as if they were attempting to railroad the president. They always offered abstruse, technical explanations, but nonetheless created an overwhelming perception of unfairness.
