I share your concerns about Trump, and have been writing for more than a year about the menace he poses. Historians typically judge leaders not on potential, but on actual accomplishments (or the lack thereof). Before he is done, Trump will almost certainly rank among our worst presidents. But if he earns the title of worst president ever, then our resistance has failed. Our goal, after all, is to shorten his term and minimize the damage he inflicts upon our country and world.
