The greatest damage done during Trump’s first year concerns neither domestic nor foreign policy, but something far deeper: it is the harm he has caused to America’s political system and to the democratic norms that underlie it. No evaluation of the impact Trump has had as president could be complete without addressing his attacks upon the rule of law, upon notions of political and racial tolerance, upon national unity, upon the freedom of the press, upon civil discourse, upon truth itself. The result has been to fray the bonds that hold American society together.
