The Democrats on Capitol Hill had three objectives in their dramatic, at times chilling, prosecution of Donald Trump in his impeachment trial before the U.S. Senate last week.
Two of the three objectives were obvious. First, alert the American people to the fragility of their democracy and warn them that another rogue president might well bring their system of government crashing down. Second, disqualify Trump from ever again seeking high office. Historians will judge whether first objective was achieved; the second was not.
